[0037] According to an embodiment of the present invention, a method for adjusting the sound effects of a vehicle is provided, wherein a touch screen is provided by a terminal device, and the terminal device can be used to run a foreground process to execute the method for adjusting the sound effects of a vehicle according to the embodiment of the present invention.

[0038] As an optional implementation, the above-described vehicle sound effect adjustment method can be applied, but is not limited to, the application scenario shown in Figure 1(a). Figure 1(a) is a schematic diagram of an application scenario of a vehicle sound effect adjustment method according to an embodiment of the present invention. As shown in Figure 1(a), in the application scenario, the terminal device 10 can communicate with the server 13 via the network 11, but is not limited to. The server 13 can perform operations on the database, such as writing or reading data. The terminal device 10 can include, but is not limited to, a touch screen, a processor, and a memory.

It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than that shown here.

[0039] For example, the vehicle sound effect adjustment method in this application can be used to provide sound effect adjustment functions for preset application scenarios. These preset application scenarios can include the following scenarios in the vehicle field: autonomous driving commuting scenarios, artificial intelligence (AI) assisted driving scenarios for family cars, automatic parking assistance (APA) scenarios (such as memory parking for self-owned parking spaces in garages, intelligent parking for designated parking spaces in parking lots, etc.), and intelligent navigation guidance (NGP) scenarios in urban or highway areas. Furthermore, the aforementioned preset application scenarios may also include, but are not limited to: intelligent transportation scenarios for intelligent driving trucks or unmanned trucks in the logistics and transportation field, and intelligent farming scenarios for autonomous agricultural vehicles in the agricultural machinery field.

[0040] When the aforementioned preset application scenario is a scenario in a field other than the vehicle field, those skilled in the art should understand that the vehicle in the above-mentioned exhaust gas recirculation system flow detection method can be replaced with other objects (e.g., agricultural machinery, drones, and robots), and correspondingly, the various devices and systems included in the vehicle can be replaced with devices and systems related to other objects. Based on this, this application embodiment takes the vehicle field as an example to illustrate the specific implementation of the above-mentioned vehicle sound effect adjustment method.

[0041] Figure 1(b) is a flowchart of a vehicle sound effect adjustment method according to an embodiment of the present invention. The vehicle may be equipped with a vehicle-mounted infotainment system and a media playback device. The vehicle-mounted infotainment system can be used to control the media playback device to perform playback operations. As shown in Figure 1(b), the method may include the following steps:

[0042] Step S112: Obtain voice information from an object in the vehicle, and identify the voiceprint information of the object from the voice information.

[0043] In the technical solution provided by step S112 of the present invention, the above-mentioned voice information may include media data to be played by the media playback device.

[0044] In this embodiment, the media data to be played may include: audio data to be played and video data to be played. The format of the audio data to be played may be at least one of the following formats: digital audio format (MPEG-1 Audio Layer 3, abbreviated as MP3) and waveform audio file format (WAV, abbreviated as WAV), etc. The format of the video data to be played may be at least one of the following formats: moving picture expert group-4 format (MP4, abbreviated as MP4), audio video interleave format (AVI, abbreviated as AVI), Matroska video format (MKV, abbreviated as MKV), QuickTime Movie format (MOV, abbreviated as MOV), and codec video format (Windows Media Video, abbreviated as WMV), etc. This is only an example and is not specifically limited.

[0045] In this embodiment, the media playback device may include the following devices: a media playback device built into the vehicle and an external media playback device connected to the vehicle's infotainment system. The media playback device built into the vehicle may include at least one of the following devices: speakers and audio equipment, etc., and the external media playback device may include at least one of the following devices: smartphones, smart speakers, and tablet computers, etc.

[0046] In this embodiment, the aforementioned voice information may further include a voice command issued by the object, which can be used to wake up the media playback device so that the media playback device enters the ready state from the cut-out state.

[0047] In this embodiment, the aforementioned voiceprint information can be used to represent the voice of an object, which can be a driver and / or passenger in a vehicle. The voiceprint information can be displayed using a voiceprint spectrum or a voiceprint feature vector. The voiceprint spectrum can be used to display features such as the frequency and amplitude of the object's voice, and is typically presented as a waveform or spectrum. Similarly, the voiceprint feature vector can also be used to display features such as the frequency and amplitude of the object's voice, and is typically presented as a sound matrix of different dimensions.

[0048] In this embodiment, voice information from an object in the vehicle is acquired, and the object's voiceprint information is identified from the voice information. Optionally, this embodiment performs voice detection on the information output by the object in the vehicle to obtain the object's voice information. Voiceprint recognition is then performed on the obtained voice information to obtain the object's voiceprint information, such as a voiceprint spectrum or voiceprint feature vector. This is merely an example and not a specific limitation.

[0049] Step S114: In response to the voiceprint information being the target voiceprint information, obtain the initial sound effect information corresponding to the media type to which the media data to be played belongs.

[0050] In the technical solution provided by step S114 of the present invention, the target voiceprint information can be used to identify the voice of a stored object.

[0051] In this embodiment, the aforementioned media type can be a music tag, which may include at least one of the following types: pop, rock, rap, jazz, electronic music, traditional Chinese music, and classical music, etc. This is only an example and is not a specific limitation.

[0052] In this embodiment, after acquiring voice information from an object in the vehicle and identifying the object's voiceprint information from the voice information, in response to the voiceprint information being the target voiceprint information, initial sound effect information corresponding to the media type to which the media data to be played belongs is acquired. Optionally, based on the identified voiceprint information of the object, this embodiment compares the identified voiceprint information with the target voiceprint information to obtain a comparison result, wherein the comparison result can be used to represent the relationship between the identified voiceprint information and the target voiceprint information. Based on the obtained comparison result, the media type to which the media data to be played belongs, and the initial sound effect information corresponding to that media type, can be obtained. For example, the initial sound effect parameters in the initial sound effect information can be obtained, wherein the initial sound effect parameters can be used to represent the initial value of the media type to which the media data to be played belongs in the equalizer (EQ). This is only an example and is not specifically limited.

[0053] Optionally, based on the comparison results, the media type of the media data to be played and the initial sound effect information corresponding to that media type can be obtained. In other words, by classifying the media data to be played based on the comparison results, the media type of the media data to be played and the initial sound effect information corresponding to that media type can be obtained.

[0054] It should be noted that the above method for obtaining the initial sound effect information corresponding to the media type of the media data to be played in response to the voiceprint information being the target voiceprint information is merely an illustrative example and is not specifically limited here. Any process and method that can obtain the initial sound effect information corresponding to the media type of the media data to be played when the voiceprint information of the object is the target voiceprint information is within the protection scope of the embodiments of the present invention, and will not be described in detail here.

[0055] Step S116: Compare the initial sound effect information with the target sound effect information corresponding to the target voiceprint information to obtain a first comparison result, and based on the first comparison result, determine the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle.

[0056] In the technical solution provided by step S116 of the present invention, the target sound effect information can be set by a stored object for a specific media type. For example, if the media type to be played is pop, the target sound effect information can be set by a stored object for pop; if the media type to be played is traditional Chinese style, the target sound effect information can be set by a stored object for traditional Chinese style. This is only an example and is not a specific limitation.

[0057] In this embodiment, the aforementioned target sound effect mode can be used to represent the playback style set for the media data to be played in the sound field area. For example, the playback style set for the media data to be played may include the following styles: cartoon style, dynamic style, original sound style, lyrical style, and cinema style, etc., which are only examples and are not specifically limited here.

[0058] In this embodiment, after obtaining the initial sound effect information corresponding to the media type of the media data to be played in response to the voiceprint information being the target voiceprint information, the initial sound effect information is compared with the target sound effect information corresponding to the target voiceprint information to obtain a first comparison result. Based on the first comparison result, the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle is determined. Optionally, based on the initial sound effect information, this embodiment can determine the target sound effect information set by the stored object for the media type of the media data to be played from the stored sound effect information set by the object for different media types. By comparing the determined initial sound effect information and the target sound effect information, a first comparison result can be obtained, wherein the first comparison result can be used to indicate whether the initial sound effect information and the target sound effect information are the same. According to the obtained first comparison result, the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle can be determined.

[0059] Optionally, by analyzing the content represented by the first comparison result above, it can be determined whether the target sound effect mode is a sound effect mode that matches the initial sound effect information or a sound effect mode that matches the target sound effect information.

[0060] It should be noted that the method described above for determining the target sound effect mode of the media data to be played in the vehicle's sound field area based on the first comparison result is merely an illustrative example and is not specifically limited here. Any process and method that can determine the target sound effect mode of the media data to be played in the vehicle's sound field area based on the relationship between the initial sound effect information and the target sound effect information described above is within the protection scope of this invention, and will not be described in detail here.

[0061] Step S118: In the target sound effect mode, control the media playback device to play the media data to be played in the sound field area.

[0062] In the technical solution provided by step S118 of the present invention, after determining the target sound effect mode for playing the media data to be played in the sound field area of ​​the vehicle based on the first comparison result, the media playback device is controlled to play the media data to be played in the sound field area under the target sound effect mode. Optionally, based on the determination of the target sound effect mode, this embodiment can control the media playback device to enter the playback state from the preparation state under the target sound effect mode. When the media playback device enters the playback state, the media playback device in the playback state is controlled to play the media data to be played in the sound field area.

[0063] As an optional example, in steps S112 to S118 of the present invention, when driving on the same route as the previous driving, the AI ​​driving assistant can be activated to enter commuting mode (in the AI ​​driving assistant of autonomous vehicles, commuting mode usually refers to a driving mode designed specifically for commuting to and from get off work or daily commuting). The AI ​​driving assistant acquires voice information from objects in the vehicle and identifies the voiceprint information of the objects from the voice information. Then, in response to the voiceprint information being the target voiceprint information, the AI ​​driving assistant determines the initial sound effect information corresponding to the media type of the media data to be played, and matches the initial sound effect information with the target sound effect information corresponding to the target voiceprint information to obtain a first matching result. Finally, based on the first matching result, the AI ​​driving assistant controls the media playback device to play the media data to be played.

[0064] It should be noted that the vehicle control method of the present invention can also be applied to at least the following scenarios: assisted driving scenarios and passive driving scenarios (which can be simply referred to as human-driven scenarios). The assisted driving scenario can be used to describe a scenario where the vehicle's control system provides assistance during driving, but the driver still needs to maintain control and supervision of the driving. The passive driving scenario can be used to describe a scenario where the driver controls the vehicle to complete driving operations.

[0065] In steps S112 to S118 of the present invention, when adjusting the vehicle's sound effects, voice information from objects in the vehicle can be acquired, and voiceprint information of the objects can be identified from the acquired voice information. In response to the identified voiceprint information being target voiceprint information, initial sound effect information corresponding to the media type of the media data to be played can be determined, and a first comparison result can be obtained by comparing the initial sound effect information with the target sound effect information corresponding to the target voiceprint information. Based on the obtained first comparison result, a target sound effect mode for playing the aforementioned media data to be played in the vehicle's sound field area can be determined, and under the determined target sound effect mode, the media playback device can be controlled to play the media data to be played in the sound field area. Since the embodiments of the present invention can identify the voiceprint information of the object from the voice information obtained from the object in the vehicle, and when the identified voiceprint information is the target voiceprint information, the initial sound effect information corresponding to the media type to which the media data to be played belongs is compared with the target sound effect information, and under the target sound effect mode determined according to the first comparison result, the media playback device can be controlled to play the media data to be played in the sound field area, thereby achieving the purpose of adjusting the playback sound effect of the media data, thus solving the technical problem of poor playback experience of media data in the vehicle, and thus achieving the technical effect of improving the playback experience of media data in the vehicle.

[0066] The method described in this embodiment will be further described below.

[0067] As an optional embodiment, step S114, in response to the voiceprint information being the target voiceprint information, obtains the initial sound effect information corresponding to the media type to which the media data to be played belongs, including: in response to the voiceprint information being the target voiceprint information, classifying the media data to be played to obtain multiple classification results; and obtaining the initial sound effect information based on the multiple classification results.

[0068] In this embodiment, the above-mentioned multiple classification results can be used to represent the degree of probability that the media data to be played belongs to different media types.

[0069] In this embodiment, after acquiring voice information from an object in the vehicle and identifying the object's voiceprint information from the voice information, the media data to be played is classified in response to the voiceprint information being the target voiceprint information, resulting in multiple classification results. Optionally, this embodiment compares the identified voiceprint information with the target voiceprint information based on the identified object's voiceprint information to obtain a comparison result. The comparison result is then judged; if it is determined that the obtained comparison result indicates that the voiceprint information is the target voiceprint information, the media data to be played is classified, resulting in multiple classification results. That is, the probability of the media data to be played belonging to different media types can be obtained. Since classifying the media data to be played allows us to determine the probability of the media data to be played belonging to different media types, this achieves the technical effect of improving the accuracy of classifying the media data to be played.

[0070] In this embodiment, in response to the voiceprint information being the target voiceprint information, the media data to be played is classified, and multiple classification results are obtained. Based on these multiple classification results, initial sound effect information is obtained. Optionally, this embodiment sorts the multiple classification results. Based on the sorted classification results, the media type to which the media data to be played belongs, and the initial sound effect information corresponding to that media type, can be determined. Since sorting the multiple classification results allows the acquisition of the initial sound effect information corresponding to the media type to which the media data to be played belongs, this achieves the technical effect of improving the efficiency of determining the initial sound effect information.

[0071] The method for obtaining initial sound effect information based on multiple classification results described in this embodiment will be further explained below.

[0072] As an optional implementation method, initial sound effect information is obtained based on multiple classification results, including: determining a first target classification result from multiple classification results; and determining the sound effect information corresponding to the media type under the media type corresponding to the first target classification result as the initial sound effect information.

[0073] In this embodiment, the probability level corresponding to the first target classification result can be greater than the probability level corresponding to the second target classification result. The second target classification result can be a classification result other than the first target classification result among multiple classification results.

[0074] In this embodiment, in response to the voiceprint information being the target voiceprint information, the media data to be played is classified, and multiple classification results are obtained. Then, a first target classification result is determined from these multiple classification results. Optionally, this embodiment sorts the multiple classification results, and from the sorted results, a first target classification result with a higher probability than the others can be determined. Since the first target classification result can be obtained by sorting the multiple classification results, the technical effect of improving the accuracy of the classification results is achieved.

[0075] In this embodiment, after determining the first target classification result from multiple classification results, the audio effect information corresponding to the media type corresponding to the first target classification result is determined as the initial audio effect information. Optionally, based on the first target classification result, this embodiment determines the audio effect information corresponding to the media type to which the media data to be played belongs as the initial audio effect information under the media type corresponding to the obtained first target classification result. Since the initial audio effect information can be determined according to the media type corresponding to the first target classification result, the technical effect of improving the efficiency of determining the initial audio effect information is achieved.

[0076] The method described below for comparing the initial sound effect information with the target sound effect information corresponding to the target voiceprint information to obtain the first comparison result will be further explained.

[0077] As an optional embodiment, step S116 compares the initial sound effect information with the target sound effect information corresponding to the target voiceprint information to obtain a first comparison result, including: determining the target sound effect information from the sound effect information set by the stored object for different media types; and comparing the initial equalization parameter in the initial sound effect information with the target equalization parameter in the target sound effect information to obtain a first comparison result.

[0078] In this embodiment, the aforementioned initial sound effect parameters can be used to represent the initial value of the media type to which the media data to be played belongs in the EQ. The aforementioned target equalization parameters can be used to represent the parameter values ​​set in the EQ for the media type to which the stored object belongs.

[0079] In this embodiment, after determining the initial sound effect information corresponding to the media type of the media data to be played in response to the voiceprint information being the target voiceprint information, the target sound effect information is determined from the stored sound effect information set by the object for different media types. Optionally, based on the determined initial sound effect information, this embodiment searches for the media type of the media data to be played from the stored sound effect information set by the object for different media types. If the media type of the media data to be played is found in the sound effect information, the target sound effect information set by the object for the media type of the media data to be played can be determined from the sound effect information. This achieves the purpose of determining the parameter value set by the object in the EQ for the media type of the media data to be played, thereby improving the accuracy of the target sound effect information.

[0080] In this embodiment, after determining the target sound effect information from the stored sound effect information set for different media types, the initial equalization parameter in the initial sound effect information is compared with the target equalization parameter in the target sound effect information to obtain a first comparison result. Optionally, based on determining the target sound effect information, this embodiment can determine the target sound effect information within the target sound effect information, and compare the initial equalization parameter in the obtained initial sound effect information with the target equalization parameter in the obtained target sound effect information to obtain a first comparison result. That is, it can determine whether the initial sound effect information and the target sound effect information are the same, thereby achieving the purpose of determining the relationship between the initial sound effect information and the target sound effect information, and thus achieving the technical effect of improving the accuracy of information matching.

[0081] The method described below for determining the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle based on the first comparison result in this embodiment will be further explained.

[0082] As an optional embodiment, step S118, based on the first comparison result, determines the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle, including: in response to the first comparison result being that the initial sound effect information and the target sound effect information are the same, determining the target sound effect mode as a sound effect mode that matches the initial sound effect information; in response to the first comparison result being that the initial sound effect information and the target sound effect information are different, determining the target sound effect mode as a sound effect mode that matches the target sound effect information.

[0083] In this embodiment, after comparing the initial sound effect information with the target sound effect information corresponding to the target voiceprint information to obtain a first comparison result, in response to the first comparison result indicating that the initial sound effect information and the target sound effect information are the same, the target sound effect mode is determined to be a sound effect mode matching the initial sound effect information. Optionally, based on the first comparison result, this embodiment further judges the obtained first comparison result. If it is judged that the obtained first comparison result indicates that the initial sound effect information and the target sound effect information are the same, then the target sound effect mode can be determined to be a sound effect mode matching the initial sound effect information. This achieves the goal of ensuring playback effect and thus realizes the technical effect of improving the playback experience of media data in the vehicle.

[0084] In this embodiment, after comparing the initial sound effect information with the target sound effect information corresponding to the target voiceprint information to obtain a first comparison result, in response to the first comparison result indicating that the initial sound effect information and the target sound effect information are different, the target sound effect mode is determined to be a sound effect mode matching the target sound effect information. Optionally, based on the first comparison result, this embodiment further judges the obtained first comparison result. If it is judged that the obtained first comparison result indicates that the initial sound effect information and the target sound effect information are different, then the target sound effect mode can be determined to be a sound effect mode matching the target sound effect information. This achieves the goal of ensuring playback effect and thus realizes the technical effect of improving the playback experience of media data in the vehicle.

[0085] The method described below for controlling a media playback device to play media data to be played in a sound field area under the target sound effect mode of this embodiment will be further explained.

[0086] As an optional embodiment, in a target sound effect mode, controlling the media playback device to play media data that satisfies the target sound effect information in the sound field area includes: responding to the target sound effect mode being a sound effect mode that matches the initial sound effect information, controlling the media playback device to play media data that satisfies the initial sound effect information in the sound field area in a sound effect mode that matches the initial sound effect information; and responding to the target sound effect mode being a sound effect mode that matches the target sound effect information, controlling the media playback device to play media data that satisfies the target sound effect information in the sound field area in a sound effect mode that matches the target sound effect information.

Optionally, this embodiment, based on determining the target sound effect mode, judges the target sound effect mode. If it is judged that the target sound effect mode is a sound effect mode matching the initial sound effect information, then the media playback device is controlled to play the media data to be played that satisfies the initial sound effect information in the sound field area under the sound effect mode matching the initial sound effect information. This achieves the purpose of ensuring playback effect and thus realizes the technical effect of improving the playback experience of media data in the vehicle.

[0088] In this embodiment, after determining the target sound effect mode for the media data to be played in the vehicle's sound field area based on the first comparison result, in response to the target sound effect mode being a sound effect mode matching the target sound effect information, the media playback device is controlled to play the media data to be played that satisfies the target sound effect information in the sound field area under the sound effect mode matching the target sound effect information. Optionally, this embodiment, based on determining the target sound effect mode, judges the target sound effect mode. If it is judged that the target sound effect mode is a sound effect mode matching the target sound effect information, then under the sound effect mode matching the target sound effect information, the media playback device is controlled to play the media data to be played that satisfies the target sound effect information in the sound field area, thereby achieving the purpose of ensuring playback effect and thus realizing the technical effect of improving the playback experience of media data in the vehicle.

[0089] The sound effect adjustment method of the vehicle described above in this embodiment will be further explained below.

[0090] As an optional embodiment, the method further includes: in response to an update of the target sound effect information, comparing the initial sound effect information with the updated target sound effect information to obtain a second comparison result; and based on the second comparison result, determining the target sound effect mode of the media data to be played in the sound field region.

[0091] In this embodiment, the second comparison result can be used to indicate whether the initial sound effect information and the updated target sound effect information are the same.

[0092] In this embodiment, in response to an update of the target sound effect information, the initial sound effect information and the updated target sound effect information are compared to obtain a second comparison result. Optionally, this embodiment monitors the state of the target sound effect information. If an update of the target sound effect information is detected, the updated target sound effect information replaces the previous target sound effect information, and the initial sound effect information and the updated target sound effect information are compared to obtain a second comparison result. That is, it can be determined whether the initial sound effect information and the updated target sound effect information are the same, thereby achieving the purpose of determining the relationship between the initial sound effect information and the updated target sound effect information, and thus achieving the technical effect of improving the accuracy of information matching.

[0093] In this embodiment, after comparing the initial sound effect information with the updated target sound effect information in response to an update of the target sound effect information to obtain a second comparison result, the target sound effect mode of the media data to be played in the sound field area is determined based on the second comparison result. Optionally, in this embodiment, based on the second comparison result, if the second comparison result shows that the initial sound effect information and the updated target sound effect information are the same, the target sound effect mode of the media data to be played in the sound field area is determined to be a sound effect mode matching the initial sound effect information; if the second comparison result shows that the initial sound effect information and the updated target sound effect information are different, the target sound effect mode of the media data to be played in the sound field area is determined to be a sound effect mode matching the target sound effect information.

[0094] Optionally, in response to the second comparison result indicating that the initial sound effect information and the updated target sound effect information are the same, the target sound effect mode for the media data to be played in the sound field area is determined to be the sound effect mode matching the initial sound effect information. In other words, by judging the obtained second comparison result, if it is determined that the initial sound effect information and the updated target sound effect information are the same, the target sound effect mode for the media data to be played in the sound field area can be determined to be the sound effect mode matching the initial sound effect information. This achieves the goal of ensuring playback quality and thus realizes the technical effect of improving the media data playback experience in the vehicle.

[0095] Optionally, in response to the second comparison result indicating that the initial sound effect information differs from the updated target sound effect information, the target sound effect mode for the media data to be played in the sound field area is determined to be a sound effect mode matching the target sound effect information. In other words, by judging the obtained second comparison result, if it is determined that the initial sound effect information differs from the updated target sound effect information, the target sound effect mode for the media data to be played in the sound field area can be determined to be a sound effect mode matching the target sound effect information. This achieves the goal of ensuring playback quality and thus realizes the technical effect of improving the media data playback experience in the vehicle.

[0096] According to an embodiment of the present invention, a method for adjusting the sound effects of a vehicle is also provided, wherein a vehicle-mounted infotainment system and a media playback device may be deployed in the vehicle, and the infotainment system may be used to control the media playback device to perform playback operations.

[0097] As an optional implementation, Figure 1(c) is a schematic diagram of another vehicle sound effect adjustment method according to an embodiment of the present invention. As shown in Figure 1(c), this method can be applied to the cloud and may include the following steps:

[0098] Step S122: Determine the target sound effect information corresponding to the target voiceprint information. The target voiceprint information is used to identify the voice of the stored object. The target sound effect information is set by the stored object for the media type to which the media data to be played belongs, including the voice information of the object.

[0099] In the technical solution provided in step S122 of the present invention, the cloud can determine the target sound effect information corresponding to the target voiceprint information. That is, the cloud can determine the target sound effect information set by the stored object for the media type to which the media data to be played belongs. Here, the cloud can also be referred to as the server, which is only an example and not a specific limitation.

[0100] Step S124: Obtain the first comparison result, wherein the first comparison result is obtained by determining the initial sound effect information corresponding to the media type in response to the voiceprint information being the target voiceprint information, and by comparing the initial sound effect information with the target sound effect information.

[0101] In the technical solution provided by step S124 of the present invention, after determining the target sound effect information corresponding to the target voiceprint information, a first comparison result is obtained. Optionally, in this embodiment, based on determining the target sound effect information corresponding to the target voiceprint information, the cloud can obtain the initial sound effect information corresponding to the media type determined in response to the voiceprint information being the target voiceprint information, and the first comparison result obtained by comparing the initial sound effect information with the target sound effect information. That is, the cloud can determine whether the initial sound effect information and the target sound effect information are the same.

[0102] In steps S122 to S124 of the present invention, when adjusting the vehicle's sound effects, based on the target sound effect information corresponding to the target voiceprint information, the server can obtain the initial sound effect information corresponding to the media type in response to the voiceprint information being the target voiceprint information, and a first comparison result obtained by comparing the initial sound effect information with the target sound effect information. Since the embodiments of the present invention can identify the voiceprint information of an object from the acquired voice information from the object in the vehicle, and when the identified voiceprint information is the target voiceprint information, the initial sound effect information corresponding to the determined media type of the media data to be played is compared with the target sound effect information, and based on the obtained first comparison result, the media playback device can be controlled to play the media data to be played in the sound field area. This achieves the purpose of adjusting the playback sound effect of the media data, thereby solving the technical problem of poor playback experience of media data in vehicles, and ultimately achieving the technical effect of improving the playback experience of media data in vehicles.

[0103] The technical solutions of the embodiments of the present invention will be illustrated below with reference to preferred embodiments.

[0104] Currently, when playing media in vehicles, users have different needs and therefore different requirements for sound effects. However, current technologies often only allow for manual adjustment of the sound effects to meet user preferences. This manual adjustment method tends to consume too much of the user's time and distract their attention, resulting in a poor media playback experience in the vehicle.

[0105] However, this invention proposes a method for adjusting the sound effects of a vehicle. This method identifies the voiceprint information of the target from the acquired voice information. If the identified voiceprint information is the target voiceprint information, it determines the initial sound effect information corresponding to the media type of the media data to be played. The initial sound effect information is compared with the target sound effect information. Based on the first comparison result, a target sound effect mode for playing the media data to be played in the vehicle's sound field area is determined. Under the determined target sound effect mode, the media playback device can be controlled to play the media data to be played. This achieves the purpose of adjusting the playback sound effects of the media data, thereby solving the technical problem of poor playback experience of media data in vehicles and ultimately improving the playback experience of media data in vehicles.

[0106] In this embodiment, the vehicle's audio adjustment method can control the media playback device to play media data to be played. For example, Figure 2(a) is a flowchart of a vehicle audio adjustment method according to an embodiment of the present invention. As shown in Figure 2(a), the vehicle audio adjustment method may include the following steps:

[0107] Step S211: Play the song and obtain the song's music tag.

[0108] In the technical solution provided in step S211 of the present invention, the user's voiceprint has been pre-recorded. By filtering the control commands issued by the user, voice commands with a clear song selection can be obtained. The voiceprint of the user who outputs the voice command is compared with the pre-recorded user voiceprint. If the pre-recorded user voiceprint includes the voiceprint of the user who output the voice command, then the preset tuning parameters saved by the user who output the voice command are read.

[0109] For example, the above voice command can be at least one of the following commands: switch to the next song, play song xx, and play a song sung by singer xx, etc. This is only an example and is not specifically limited.

[0110] After playing the song and obtaining its music tag, proceed to step S212, where the music tag is matched with the preset tuning parameters in the cloud.

[0111] In the technical solution provided by step S212 of the present invention, in the cloud, the music tag to which the media data to be played belongs is compared with the music tag saved by the user who output the voice command. If the comparison shows that the music tag saved by the user who output the voice command includes the music tag to which the media data to be played belongs, then the preset tuning parameters that match the music tag saved by the user who output the voice command are downloaded.

[0112] For example, as shown in Table 1 below, first obtain the categories from different music applications, then align the obtained categories with the categories in the car's infotainment system to obtain music tags. The music tags mentioned above can include at least one of the following types: pop, rock, rap, jazz, electronic music, traditional Chinese music, and classical music, etc., which are only examples and are not specifically limited.

[0113] Table 1 Classification Mapping Table

[0114]

[0115] After matching the music tag with the preset tuning parameters in the cloud, step S213 is performed to match the initial tuning parameters of the music with the preset tuning parameters and to control the media playback device to play the music.

[0116] In the technical solution provided by step S213 of the present invention, the preset tuning parameters are sent to the local device, and the initial tuning parameters of the music are matched with the preset tuning parameters. If the initial tuning parameters of the music are successfully matched with the preset tuning parameters, the media playback device is controlled to play music that meets the initial tuning parameters. If the initial tuning parameters of the music are not matched with the preset tuning parameters, the initial tuning parameters are adjusted to the preset tuning parameters, and the media playback device is controlled to enter the playback state from the preparation state. When the media playback device enters the playback state, the media playback device is controlled to play music that meets the preset tuning parameters.

[0117] In this embodiment, the media audio parameters of the vehicle can be as shown in Figure 2(b). For example, Figure 2(b) is a schematic diagram of the media audio parameters of a vehicle according to an embodiment of the present invention. The EQ parameters may include the following parameters: sub-bass parameter, bass parameter, mid-range parameter, treble parameter, and super-treble parameter. These are only illustrative examples and are not specifically limited. By sliding the tuning buttons corresponding to the above parameters, the corresponding parameters can be adjusted, thereby achieving the purpose of adjusting the EQ parameters.

[0118] In this embodiment, the media playback device can be controlled to play media data by exchanging data between the vehicle and the server. For example, Figure 2(c) is a schematic diagram of data interaction between a vehicle and a server according to an embodiment of the present invention. As shown in Figure 2(c), if the vehicle 222 uploads the voiceprint information of an object in the vehicle that is the same as the target voiceprint information to the server 221, the server 221 can send the target sound effect information corresponding to the target voiceprint information to the vehicle 222 so that the initial sound effect information and the target sound effect information corresponding to the target voiceprint information can be compared in the vehicle 222 to obtain a first comparison result. Based on the obtained first comparison result, the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle can be determined. Under the determined target sound effect mode, the media playback device can be controlled to play the media data to be played in the sound field area. For example, the built-in audio system of the vehicle can be controlled to play music in the entire sound field area of ​​the vehicle. This is only an example and is not specifically limited.

[0119] In this embodiment, when adjusting the vehicle's sound effects, voice information from objects within the vehicle can be acquired, and the voiceprint information of the objects can be identified from the acquired voice information. In response to the identified voiceprint information being the target voiceprint information, initial sound effect information corresponding to the media type of the media data to be played can be determined. A first comparison result can be obtained by comparing the initial sound effect information with the target sound effect information corresponding to the target voiceprint information. Based on the obtained first matching result, a target sound effect mode for playing the aforementioned media data in the vehicle's sound field area can be determined. Under the determined target sound effect mode, the media playback device can be controlled to play the media data in the sound field area. This achieves the purpose of adjusting the playback sound effects of the media data, thereby solving the technical problem of poor playback experience of media data in vehicles, and ultimately achieving the technical effect of improving the playback experience of media data in vehicles.
