[0041] FIG1(b) is a flow chart of a method for adjusting the sound effect of a vehicle according to an embodiment of the present invention. The vehicle may be equipped with a vehicle computer and a media player. The vehicle computer may be used to control the media player to perform a playback operation. As shown in FIG1(b), the method may include the following steps:

[0042] Step S112, acquiring voice information from an object in the vehicle, and identifying the voiceprint information of the object from the voice information.

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

[0044] In this embodiment, the above-mentioned 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 format (Waveform Audio File Format, abbreviated as WAV), etc. The format of the video data to be played may be at least one of the following formats: moving picture experts group-4 (MP4), audio video interleave format (AVI), Matroska video format (MKV), quick time movie format (MOV) and codec video format (WMV), etc., which are only given as examples here and are not specifically limited.

[0045] In this embodiment, the above-mentioned media playback device may include the following devices: a built-in media playback device in the vehicle and an external media playback device connected to the vehicle computer, etc. The built-in media playback device in the vehicle may include at least one of the following devices: a speaker and a stereo, etc., and the external media playback device may include at least one of the following devices: a smart phone, a smart stereo and a tablet computer, etc.

[0046] In this embodiment, the voice information may also include a voice instruction issued by the object, and the voice instruction may be used to wake up the media playback device so as to enable the media playback device to enter a ready state from a switched-out state.

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

[0048] In this embodiment, voice information from an object in the vehicle is obtained, and the voiceprint information of the object 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 voice information of the object. Voiceprint recognition is performed on the obtained voice information to obtain the voiceprint information of the object, for example, the voiceprint spectrum or voiceprint feature vector of the object can be obtained, which is only used as an example and is not specifically limited.

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

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

[0051] In this embodiment, the above-mentioned media type can be a music tag, and the music tag can include at least one of the following types: pop type, rock type, rap type, jazz type, electronic music type, Chinese style type and classical type, etc., which are only given as examples here and are not specifically limited.

[0052] In this embodiment, after acquiring voice information from an object in the vehicle and identifying the voiceprint information of the object 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 can be acquired, as well as the initial sound effect information corresponding to the media type. For example, the initial sound effect parameters in the initial sound effect information can be acquired, 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), which is only used as an example and is not specifically limited.

[0053] Optionally, based on the comparison result, the media type to which the media data to be played belongs can be obtained, and the initial sound effect information corresponding to the media type can be obtained. In other words, based on the comparison result, the media data to be played is classified, and the media type to which the media data to be played belongs can be obtained, and the initial sound effect information corresponding to the media type can be obtained.

[0054] It should be noted that the above method of obtaining the initial sound effect information corresponding to the media type to which the media data to be played belongs in response to the voiceprint information being the target voiceprint information is only an example and is not specifically limited here. Any process and method that can obtain the initial sound effect information corresponding to the media type to which the media data to be played belongs 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 one by one here.

[0055] Step S116, comparing 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, determining a target sound effect mode for playing the media data to be played in the sound field area of ​​the vehicle.

[0056] In the technical solution provided in the above step S116 of the present invention, the above target sound effect information can be set by a stored object for a media type. For example, if the media type to which the to-be-played media data belongs is a popular type, the above target sound effect information can be set by a stored object for a popular type; if the media type to which the to-be-played media data belongs is a traditional Chinese type, the above target sound effect information can be set by a stored object for a traditional Chinese type. This is only an example and is not specifically limited.

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

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

[0059] Optionally, by analyzing the content represented by the above-mentioned first comparison result, 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 above method 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 is only an example and is not specifically limited here. As long as the process and method can determine the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle on the basis of obtaining the relationship between the above initial sound effect information and the above target sound effect information, they are all within the protection scope of the embodiments of the present invention and will not be described one by one here.

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

[0062] In the technical solution provided in the above 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 in the target sound effect mode. Optionally, based on the determination of the target sound effect mode, in the above target sound effect mode, the embodiment can control the media playback device to enter the playback state from the preparation state, and when the media playback device enters the playback state, the media playback device that has entered the playback state is controlled to play the media data to be played in the sound field area.

[0063] As an optional example, in the above steps S112 to S118 of the present invention, when the same route as the last time you drove is chosen for this driving, the AI ​​driver can be activated to enter the commuting mode (in the artificial intelligence AI driver of an autonomous driving vehicle, the commuting mode generally refers to a driving mode designed for commuting or daily commuting). The AI ​​driver obtains voice information from an object in the vehicle and identifies the voiceprint information of the object from the voice information. Then, in response to the voiceprint information being the target voiceprint information, the AI ​​driver determines the initial sound effect information corresponding to the media type to which the media data to be played belongs, 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 ​​driver 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 scenario and passive driving scenario (which can be referred to as human driving scenario). Among them, the assisted driving scenario can be used to indicate a scenario in which the vehicle control system provides assistance during the driving process, but the driver still needs to maintain control and supervision of the driving, and the passive driving scenario can be used to indicate a scenario in which the driver controls the vehicle to complete the driving operation.

[0065] In the above steps S112 to S118 of the present invention, when adjusting the sound effects of the vehicle, voice information from an object in the vehicle can be obtained, and the voiceprint information of the object can be identified from the obtained voice information. In response to the identified voiceprint information being the target voiceprint information, the initial sound effect information corresponding to the media type to which the media data to be played belongs can be determined, and the initial sound effect information can be compared with the target sound effect information corresponding to the target voiceprint information to obtain a first comparison result. 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, 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 embodiment 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 determined media data to be played belongs is compared with the target sound effect information, and in the target sound effect mode determined according to the above-mentioned 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, thereby solving the technical problem of poor playback experience of the vehicle's media data, and further achieving the technical effect of improving the playback experience of the vehicle's media data.

[0066] The above method of this embodiment is further introduced below.

[0067] As an optional implementation method, step S114, in response to the voiceprint information being the target voiceprint information, obtaining initial sound effect information corresponding to the media type to which the media data to be played belongs, includes: 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 initial sound effect information based on the multiple classification results.

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

[0069] In this embodiment, after acquiring voice information from an object in a vehicle and identifying the voiceprint information of the object from the voice information, in response to the voiceprint information being the target voiceprint information, the media data to be played is classified to obtain multiple classification results. 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. The obtained comparison result is judged. If it is judged that the obtained comparison result indicates that the voiceprint information is the target voiceprint information, the media data to be played is classified to obtain multiple classification results, that is, the degree of possibility that the media data to be played belongs to different media types can be obtained. Since the degree of possibility that the media data to be played belongs to different media types can be obtained by classifying the media data to be played, the technical effect of improving the accuracy of classifying the media data to be played is achieved.

[0070] In this embodiment, in response to the voiceprint information being the target voiceprint information, the media data to be played is classified, and after a plurality of classification results are obtained, initial sound effect information is obtained based on the plurality of classification results. Optionally, on the basis of obtaining a plurality of classification results, the embodiment sorts the plurality of classification results, and according to the sorted classification results, the media type to which the media data to be played belongs and the initial sound effect information corresponding to the media type can be determined. Since the plurality of classification results are sorted, the initial sound effect information corresponding to the media type to which the media data to be played belongs can be obtained, thereby achieving a technical effect of improving the efficiency of determining the initial sound effect information.

[0073] In this embodiment, the possibility degree corresponding to the first target classification result may be greater than the possibility degree corresponding to the second target classification result. The second target classification result may be a classification result other than the first target classification result among the 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 after obtaining multiple classification results, a first target classification result is determined from the multiple classification results. Optionally, on the basis of obtaining multiple classification results, this embodiment sorts the multiple classification results, and from the sorted classification results, a first target classification result with a higher probability than other probability can be determined.

Optionally, based on the first target classification result obtained, under the media type corresponding to the first target classification result obtained, this embodiment determines the sound effect information corresponding to the media type as the initial sound effect information corresponding to the media type to which the media data to be played belongs. Since the initial sound 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 sound effect information is achieved.

[0080] In this embodiment, after determining the target sound effect information from the sound effect information set for different media types by the stored objects, the initial equalization parameters in the initial sound effect information are compared with the target equalization parameters in the target sound effect information to obtain a first comparison result. Optionally, this embodiment can determine the target sound effect information in the target sound effect information on the basis of determining the target sound effect information, and compare the initial equalization parameters in the obtained initial sound effect information with the target equalization parameters in the obtained target sound effect information to obtain a first comparison result, that is, it can be determined whether the above-mentioned initial sound effect information is the same as the above-mentioned target sound effect information, thereby achieving the purpose of being able to determine the relationship between the above-mentioned initial sound effect information and the above-mentioned target sound effect information, and further achieving the technical effect of being able to improve the accuracy of information matching.

Optionally, this embodiment judges the target sound effect mode on the basis of determining the target sound effect mode. If it is judged that the target sound effect mode is a sound effect mode that matches the initial sound effect information, then under the above-mentioned sound effect mode that matches the initial sound effect information, the media playback device is controlled to play the media data to be played that meets the initial sound effect information in the sound field area, thereby achieving the purpose of ensuring the playback effect, and further realizing the technical effect of improving the playback experience of the vehicle's media data.

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

[0092] In this embodiment, in response to the target sound effect information being updated, the initial sound effect information is compared with the updated target sound effect information to obtain a second comparison result. Optionally, this embodiment monitors the state of the target sound effect information, and if it is detected that the target sound effect information is updated, the target sound effect information before the update is replaced with the updated target sound effect information, and the initial sound effect information is compared with the updated target sound effect information to obtain a second comparison result, that is, it can be determined whether the initial sound effect information is the same as the updated target sound effect information, thereby achieving the purpose of determining the relationship between the above-mentioned initial sound effect information and the above-mentioned updated target sound effect information, and further achieving the technical effect of improving the accuracy of information matching.

[0093] In this embodiment, in response to the target sound effect information being updated, the initial sound effect information is compared with the updated target sound effect information, and after obtaining 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.

In other words, the second comparison result is judged, and if it is judged that the second comparison result is that the initial sound effect information is the same as the updated target sound effect information, it can be determined that the target sound effect mode of the media data to be played in the sound field area is a sound effect mode that matches the initial sound effect information, thereby achieving the purpose of ensuring the playback effect, and further realizing the technical effect of improving the playback experience of the vehicle's media data.

[0095] Optionally, in response to the second comparison result being that the initial sound effect information is different from the updated target sound effect information, it is determined that the target sound effect mode of the media data to be played in the sound field area is a sound effect mode that matches the target sound effect information.

[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 computer and a media player may be deployed in the vehicle, and the vehicle computer may be used to control the media player to perform a playback operation.

[0097] As an optional implementation, FIG1(c) is a schematic diagram of another method for adjusting the sound effect of a vehicle according to an embodiment of the present invention. As shown in FIG1(c), the method can be applied to the cloud, and the method may include the following steps:

[0098] Step S122, determining the target sound effect information corresponding to the target voiceprint information, wherein the target voiceprint information is used to identify the sound of a stored object, the target sound effect information is set by the stored object according to the media type to which the to-be-played media data included in the voice information belongs, the voice information is from an object in the vehicle, and the voice information includes the voiceprint 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. The cloud can also be referred to as the server, which is only used as an example here and is not specifically limited.

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

[0101] In the technical solution provided in 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 in response to the voiceprint information being the target voiceprint information, and compare the initial sound effect information with the target sound effect information to obtain the first comparison result. In other words, the cloud can obtain whether the initial sound effect information is the same as the target sound effect information.

[0102] In the above steps S122 to S124 of the present invention, when adjusting the sound effects of the vehicle, 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 the first comparison result obtained by comparing the initial sound effect information with the target sound effect information, based on the target sound effect information corresponding to the target voiceprint information. Since the embodiment 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 determined to be compared with the target sound effect information, and according to the first comparison result obtained, 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 effects of the media data, thereby solving the technical problem of poor playback experience of the vehicle's media data, and further achieving the technical effect of improving the playback experience of the vehicle's media data.

[0103] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0104] At present, when playing media data in a vehicle, due to different user requirements for playback, users have different required sound effects for playing media data. However, in the related art, the sound effects of playing media data can only be adjusted manually to meet the user's playback needs. Such manual adjustment method often takes up too much time of the user and also distracts the user's attention, thus leading to the technical problem of poor playback experience of media data in the vehicle.

[0105] However, an embodiment of the present invention proposes a method for adjusting the sound effects of a vehicle, in which the voiceprint information of an object is identified from the voice information of the object, and if 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 determined, and the initial sound effect information is compared with the target sound effect information. Based on the first comparison result obtained, the target sound effect mode for playing the above-mentioned media data to be played in the sound field area of ​​the vehicle 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, thereby achieving the purpose of adjusting the playback sound effect of the media data, thereby solving the technical problem of poor playback experience of the media data of the vehicle, and further achieving the technical effect of improving the playback experience of the media data of the vehicle.

[0106] In this embodiment, the vehicle sound effect adjustment method can be used to control the media playback device to play the media data to be played. For example, FIG2(a) is a flow chart of a vehicle sound effect adjustment method according to an embodiment of the present invention. As shown in FIG2(a), the vehicle sound effect adjustment method may include the following steps:

[0107] Step S211, play the song and obtain the music tag of the song.

[0108] In the technical solution provided in the above step S211 of the present invention, the user voiceprint has been recorded in advance. The control instructions issued by the user are screened to obtain a voice instruction with a clear song request. The voiceprint of the user who outputs the voice instruction is compared with the recorded user voiceprint. If the recorded user voiceprint includes the voiceprint of the user who outputs the voice instruction, the pre-made tuning parameters saved by the user who outputs the voice instruction are read.

[0109] For example, the voice command may be at least one of the following commands: switch to the next song, play xx song, and play songs sung by xx singer, etc. These are merely examples and are not specifically limited.

[0110] After playing the song and obtaining the music tag of the song, enter step S212 to match the music tag with the pre-made tuning parameters in the cloud.

[0111] In the technical solution provided in the above step S212 of the present invention, in the cloud, the music tags belonging to the media data to be played are compared with the music tags saved by the user who outputs the voice command. If it is compared that the music tags saved by the user who outputs the voice command include the music tags belonging to the media data to be played, the pre-made tuning parameters matching the music tags saved by the user who outputs the voice command are downloaded.

[0112] For example, as shown in Table 1 below, the categories in different music applications are first obtained, and then the obtained categories are aligned with the categories in the vehicle computer to obtain music tags. The above music tags may include at least one of the following types: pop type, rock type, rap type, jazz type, electronic music type, Chinese style type and classical type, etc., which are only used as examples and are not specifically limited.

[0113] Table 1 Classification mapping table

[0114]

[0115] After the music tags are matched with the pre-made tuning parameters in the cloud, step S213 is entered to match the initial tuning parameters of the music with the pre-made tuning parameters, and the media playback device is controlled to play the music.

[0116] In the technical solution provided in the above step S213 of the present invention, the prefabricated tuning parameters are sent to the local, and the initial tuning parameters of the music are matched with the prefabricated tuning parameters. If the initial tuning parameters of the music are successfully matched with the prefabricated tuning parameters, the media playback device is controlled to play the music that meets the initial tuning parameters; if the initial tuning parameters of the music are not matched with the prefabricated tuning parameters, the initial tuning parameters are adjusted to the prefabricated 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 the music that meets the prefabricated tuning parameters.

[0117] In this embodiment, the media sound effect parameters of the above-mentioned vehicle may be as shown in FIG2(b). For example, FIG2(b) is a schematic diagram of the media sound effect parameters of a vehicle according to an embodiment of the present invention, and the EQ parameters may include the following parameters: sub-bass parameters, bass parameters, mid-range parameters, treble parameters, and super-treble parameters, which are only used as examples and are not specifically limited. By sliding the tuning buttons corresponding to the above-mentioned 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 the media data to be played by exchanging data between the vehicle and the server. For example, FIG2(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 FIG2(c), if the vehicle 222 uploads the voiceprint information of the 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 as to compare the initial sound effect information with the target sound effect information corresponding to the target voiceprint information in the vehicle 222 to obtain a first comparison result, and 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, 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, for example, the built-in audio of the vehicle is controlled to play music in the sound field area of ​​the whole vehicle. This is only an example and is not specifically limited.

[0119] In this embodiment, when adjusting the sound effect of the vehicle, voice information from an object in the vehicle can be obtained, and the voiceprint information of the object can be identified from the obtained voice information. In response to the identified voiceprint information being the target voiceprint information, the initial sound effect information corresponding to the media type to which the media data to be played belongs can be determined, and the target sound effect information corresponding to the target voiceprint information can be compared with the initial sound effect information to obtain a first comparison result. According to the obtained first matching result, the target sound effect mode of the media data to be played in the sound field area of ​​the vehicle 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, thereby achieving the purpose of adjusting the playback sound effect of the media data, thereby solving the technical problem of poor playback experience of the media data of the vehicle, and further achieving the technical effect of improving the playback experience of the media data of the vehicle.
