Description

Technical Field

[0001] The present application relates to multimedia technology, specifically to audio processing technology, and in particular to a method, device, system, equipment and medium for playing audio data. Background Art

[0002] At present, map applications APP play a key role in car driving. They can assist drivers in driving through voice prompts, such as where to turn, where to get on and off the highway, which lane to enter, etc.; in addition, voice prompts can also provide real-time reports on road conditions, surrounding attractions, landmarks, etc.

[0003] However, the sound of these announcements is only fixed audio and not accurate enough, which will affect the driver's judgment. Moreover, if the driver still spends energy to check the electronic map while driving, it will be detrimental to safe driving. In addition, some voice announcements with obvious directional information, such as "the destination is on your left", "800m ahead, on the right side of the road...", etc., are often disturbed by the conversations of people in the car, or ignored because the driver is focused on the road conditions. At this time, the so-called directional prompts are useless.

[0004] Long-term driving without prompts can easily lead to driver fatigue and a sharp increase in driving risks. However, current map application apps are unable to solve the above problems and are unable to accurately and effectively determine and play in-vehicle audio data based on accurate vehicle driving information.

DETAILED DESCRIPTION

[0058] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0059] First, the terms involved in this application are explained:

[0060] WANOS refers to the world's highest audio technology standard at this stage, and is widely used in panoramic sound movies, ultra-high-definition television, Internet broadband audio and video services, digital audio and video broadcasting, wireless broadband multimedia communications, virtual reality and augmented reality, and video surveillance.

[0061] Example 1

[0062] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0063] The audio data playback method provided by the present application is intended to solve the above technical problems of the prior art. The audio data playback method can be applied to Figure 1 A schematic diagram of the architecture of an audio data playback system is shown in FIG. Figure 1 As shown, the audio data playback system includes:

[0064] The vehicle terminal 100 is used to send an audio data acquisition request through a locally running audio playback application, and to play the vehicle audio data according to the real-time position information of the vehicle;

[0065] The server 200 communicates with the vehicle-mounted terminal 100 and is used to determine the audio data application scenario of the vehicle-mounted terminal in response to the audio data acquisition request; and acquire corresponding vehicle-mounted audio data according to the audio data application scenario.

[0066] In an optional implementation manner, the above-mentioned audio data acquisition request is generated based on a user instruction, or is automatically generated based on the real-time location information of the user in the above-mentioned audio data application scenario after the user starts the application.

[0067] Optionally, the above-mentioned audio data application scenarios may include but are not limited to: city self-driving tours, sightseeing tours of historical sites, natural scenery exploration and other application scenarios. The vehicle-mounted terminal can communicate with the cloud server during the vehicle's driving process to obtain the vehicle-mounted audio data according to the audio data application scenario, and play the vehicle-mounted audio data based on the real-time location information of the vehicle.

[0068] In the embodiment of the present application, by responding to the audio data acquisition request, the audio data application scenario of the vehicle terminal is determined, thereby realizing the intelligent acquisition of audio data, and by playing the vehicle audio data according to the real-time position information of the vehicle, thereby realizing the intelligent playback of audio data. By playing the audio data, the user is prevented from performing manual operations during driving, thereby reducing driving safety risks and interference.

[0069] For example, when a user drives a vehicle across a historic bridge, the vehicle terminal sends an audio data acquisition request through a locally running audio playback application (e.g., an application such as a sound map). In response to the request, the server parses the geographic location information and application information of the vehicle terminal carried in the request, and determines that the audio data application scenario of the vehicle terminal is to introduce the "history and culture of the XX ancient bridge", etc. The server obtains the corresponding vehicle audio data according to the scenario, such as an introduction to the history, culture, and stories of the bridge.

[0070] Furthermore, the vehicle terminal plays the vehicle audio data according to the real-time location information of the vehicle. For example, when it is detected that the vehicle has reached the bridge head, the vehicle terminal is controlled to play some history, stories, anecdotes, etc. about the bridge head, and according to the change of the vehicle's driving position, the vehicle terminal is controlled in real time to transition to the explanation and introduction related to the corresponding position. In addition, when the user drives the vehicle away from the bridge, the vehicle terminal updates or stops playing the vehicle audio data according to the real-time location information of the vehicle to enhance the temporal and spatial correlation and adaptability of the audio data.

[0071] For another example, in response to detecting that the vehicle is within 200m of the historical monument "XX Pavilion", the audio data of a solitary wild goose flying can be played. The prompting effect of the intuitive and vivid audio is far stronger than the stereotyped and slowly output established voice. In this way, the audio data played in the vehicle can be combined with the real-time location information of the vehicle, and the vehicle terminal can be controlled to play the vehicle audio data at an appropriate location inside the vehicle to improve the driver's concentration and excitement, facilitate the driver to make accurate judgments, reduce unnecessary detours or waiting, and improve safety.

[0072] The audio data playback system provided in the embodiment of the present application can be implemented based on panoramic sound technology. Among them, panoramic sound technology is the most representative cinema audio technology that has emerged in recent years. It can perform three-dimensional rendering of sound objects based on movie scenes to achieve dynamic sound effects and create an immersive auditory effect. This is fundamentally different from the so-called "stereo" of ordinary theaters, and can achieve a more realistic panoramic auditory experience.

[0073] Optionally, the audio data based on panoramic sound technology in the embodiment of the present application can be audio data in video works uploaded by the client, downloaded audio works, filmed film and television works, video works, etc., or it can be audio data downloaded from the Internet based on the client's download request. The client can be any device capable of data processing and data transmission.

[0074] In an optional embodiment, the in-vehicle audio data may be played and presented in panoramic sound to provide users with a better sense of immersion and interactivity.

[0075] In the embodiment of the present application, first, according to the audio data acquisition request of the vehicle terminal, the audio data application scenario of the vehicle terminal is determined, so as to obtain the vehicle audio data that matches the environment of the vehicle terminal and the user's needs, and improve the user's auditory experience and satisfaction. Secondly, the vehicle terminal can also play the vehicle audio data according to the real-time location information of the vehicle, so as to realize the dynamic update and adjustment of the audio data, and enhance the temporal and spatial correlation and adaptability of the audio data. Thirdly, the audio data can also be played, so as to avoid the user from performing manual operations during driving, and reduce driving safety risks and interference.

[0076] Example 2

[0077] The present application provides a method for playing audio data. Figure 2 is a flowchart of a method for playing audio data provided by an embodiment of the present application, such as Figure 2 As shown, the method includes:

[0078] S101, in response to an audio data acquisition request, determining an audio data application scenario of a vehicle-mounted terminal;

[0079] S102, acquiring corresponding in-vehicle audio data according to the above audio data application scenario;

[0080] S103, controlling the vehicle-mounted terminal to play the vehicle-mounted audio data accordingly according to the real-time position information of the vehicle.

[0081] In an optional implementation, the audio data acquisition request is generated based on a user instruction, or is automatically generated after an audio playback application is started and a vehicle's driving route is determined.

[0082] Optionally, the above-mentioned audio data application scenarios may include but are not limited to: city self-driving tours, sightseeing tours, natural scenery exploration and other application scenarios. The vehicle-mounted terminal can communicate with the cloud server during the vehicle's driving process to obtain the vehicle-mounted audio data from the cloud server in real time according to the audio data application scenario. In this way, the vehicle-mounted terminal can play the vehicle-mounted audio data according to the real-time location information of the vehicle.

[0083] In the embodiment of the present application, by responding to the audio data acquisition request, the audio data application scenario of the vehicle terminal is determined, thereby realizing the intelligent acquisition of audio data, and by playing the vehicle audio data according to the real-time position information of the vehicle, thereby realizing the intelligent playback of audio data. By playing the audio data, the user is prevented from performing manual operations during driving, thereby reducing driving safety risks and interference.

[0084] For example, when a user drives a vehicle across a historic bridge, the vehicle terminal sends an audio data acquisition request through a locally running audio playback application (e.g., an application such as a sound map). In response to the request, the server parses the geographic location information and application information of the vehicle terminal carried in the request, and determines that the audio data application scenario of the vehicle terminal is to introduce the "history and culture of the XX ancient bridge", etc. Based on the audio data application scenario, the vehicle terminal obtains the corresponding vehicle audio data locally or from the cloud server, such as an introduction to the history, culture, and stories of the bridge.

[0085] Furthermore, the vehicle terminal plays the vehicle audio data according to the real-time location information of the vehicle. For example, when it is detected that the vehicle is driving to the bridge head, the vehicle terminal is controlled to play some history, stories, anecdotes, etc. about the bridge head, and according to the change of the driving position of the vehicle, the vehicle terminal is controlled in real time to transition to the explanation and introduction related to the corresponding position. In addition, when the user drives the vehicle away from the bridge, the vehicle terminal can update or stop playing the vehicle audio data according to the real-time location information of the vehicle to enhance the temporal and spatial correlation and adaptability of the audio data.

[0086] For another example, in response to detecting that the vehicle is within 200 meters of the historical monument "XX Pavilion", the audio data of a solitary wild goose flying can be played. The prompting effect of the intuitive and vivid audio is far stronger than the stereotyped and slowly output established voice. In this way, the audio data played in the vehicle can be combined with the real-time location information of the vehicle, and the speaker of the vehicle terminal at an appropriate position inside the vehicle can be controlled to play the vehicle audio data, so as to improve the driver's concentration and excitement, facilitate the driver to make accurate judgments, reduce unnecessary detours or waiting, and improve safety.

[0087] It should be noted that in the embodiment of the present application, not only can the acquisition of vehicle-mounted audio data be completed on the cloud server, but the audio data acquisition request can also be parsed locally by the vehicle-mounted terminal to parse the audio data application scenario adapted to the vehicle-mounted terminal, and the corresponding vehicle-mounted audio data can be obtained locally at the terminal or from the cloud server.

[0088] The method for playing audio data provided in the embodiment of the present application can be implemented based on panoramic sound technology. Among them, panoramic sound technology is the most representative cinema audio technology that has emerged in recent years. It can perform three-dimensional rendering of sound objects based on movie scenes to achieve dynamic sound effects and create an immersive auditory effect. This is fundamentally different from the so-called "stereo" of ordinary theaters, and can achieve a more realistic panoramic auditory experience.

[0089] Optionally, the audio data based on panoramic sound technology in the embodiment of the present application can be audio data in video works uploaded by the client, downloaded audio works, filmed film and television works, video works, etc., or it can be audio data downloaded from the Internet based on the client's download request. The client can be any device capable of data processing and data transmission.

[0090] In an optional embodiment, the in-vehicle audio data may be played and presented in panoramic sound to provide users with a better sense of immersion and interactivity.

[0091] In the embodiment of the present application, first, according to the audio data acquisition request of the vehicle terminal, the audio data application scenario of the vehicle terminal is determined, so as to obtain the vehicle audio data that matches the environment of the vehicle terminal and the user's needs, and improve the user's auditory experience and satisfaction. Secondly, the vehicle audio data can also be played according to the real-time location information of the vehicle, so as to realize the dynamic update and adjustment of the audio data and enhance the spatiotemporal correlation and adaptability of the audio data. Thirdly, the audio data can also be played, so as to avoid the user from performing manual operations during driving and reduce driving safety risks and interference.

[0092] The embodiments of the present application can improve the user's auditory experience and satisfaction, that is, provide the user with audio data that matches their environment and needs, thereby increasing the user's interest and sense of participation; provide the user with dynamically updated and adjusted audio data, thereby increasing the user's surprise and freshness; provide the user with an audio playback style that adapts to their environment, thereby increasing the user's comfort and sense of adaptation.

[0093] By adopting the embodiments of the present application, the matching degree, relevance and adaptability of audio data can be improved, that is, vehicle-mounted audio data matching the vehicle-mounted terminal environment and user needs can be obtained; the audio data can be dynamically updated and adjusted according to the real-time location information of the vehicle; and the audio playback style can be determined according to the environmental characteristics of the vehicle-mounted terminal environment.

[0094] In an optional implementation, Figure 3 is a flowchart of an optional method for playing audio data provided in an embodiment of the present application, such as Figure 3 As shown, in response to the audio data acquisition request, determining the audio data application scenario of the vehicle terminal includes:

[0095] S201, parsing the audio data acquisition request to obtain the geographical location information of the vehicle-mounted terminal carried in the audio data acquisition request;

[0096] S202: Determine an audio data application scenario of the vehicle-mounted terminal according to the geographic location information.

[0097] Optionally, in the above embodiment, the audio data application scenario of the vehicle terminal is determined by parsing the geographic location information of the vehicle terminal carried in the audio data acquisition request, thereby improving the accuracy and precision of determining the audio data application scenario. The method can determine the specific environment and regional characteristics of the vehicle terminal based on the geographic location information of the vehicle terminal, thereby obtaining an audio data application scenario that matches it, improving the relevance and adaptability of the audio data application scenario, and realizing intelligent matching of the audio data application scenario.

[0098] For example, taking the server cloud-assisted processing as an example, when the user drives the vehicle across a historic bridge, the vehicle terminal sends an audio data acquisition request through the locally running audio playback application. The server responds to the request and parses the geographic location information of the vehicle terminal carried in the request, such as longitude and latitude, altitude, direction, etc. Based on the geographic location information, the server determines the specific environment and geographical characteristics of the vehicle terminal, such as cities, streets, buildings, scenery, etc. Based on these environmental and geographical characteristics, the audio data application scenario of the vehicle terminal is determined to be "historical culture". After that, the vehicle terminal obtains the corresponding vehicle audio data according to the scenario and controls the corresponding speakers to play.

[0099] In an embodiment of the present application, by parsing the geographic location information of the vehicle-mounted terminal carried in the audio data acquisition request, the precision and accuracy of determining the application scenario of the audio data are improved; and, the method determines the application scenario of the audio data only based on the geographic location information of the vehicle-mounted terminal without considering the application program information, thereby simplifying the process of determining the application scenario of the audio data.

[0100] In an optional implementation, Figure 4 is a flowchart of an optional method for playing audio data provided in an embodiment of the present application, such as Figure 4 As shown, in response to the audio data acquisition request, determining the audio data application scenario of the vehicle terminal includes:

[0101] S301, parsing the audio data acquisition request to obtain the geographic location information and application information of the vehicle-mounted terminal carried in the audio data acquisition request;

[0102] S302: Determine an application scenario of the audio data according to the application information and the geographic location information.

[0103] In an embodiment of the present application, the audio data application scenario of the vehicle terminal is determined based on the application information and geographic location information of the vehicle terminal, so as to obtain vehicle audio data that matches the environment of the vehicle terminal and user needs, thereby improving the relevance and adaptability of the audio data application scenario.

[0104] For example, the audio data application scenario of the vehicle terminal is determined based on the application information and geographic location information of the vehicle terminal, thereby realizing intelligent matching of the audio data application scenario. For another example, the audio data application scenario adapted to the different applications used by the user is obtained to meet the user's personalized needs.

[0105] In the above embodiment, by parsing the geographic location information and application information of the vehicle-mounted terminal carried in the audio data acquisition request, the precision and accuracy of determining the application scenario of the audio data are improved; compared with the method provided by the above steps S201-202, in addition to determining the application scenario of the audio data based on the geographic location information of the vehicle-mounted terminal, this method embodiment also takes into account the application information, thereby improving the relevance and adaptability of the audio data application scenario.

[0106] For example, in one example, taking the server cloud-assisted processing as an example, when the user drives the vehicle through a historic bridge, the vehicle terminal sends an audio data acquisition request through the locally running navigation application. The server responds to the request and parses the geographic location information and application information of the vehicle terminal carried in the request, such as latitude and longitude, altitude, direction, navigation, etc. Based on the application information and geographic location information, the server determines that the audio data application scenario of the vehicle terminal is "navigation + history and culture". Then, the vehicle terminal obtains the corresponding vehicle audio data according to the scenario and controls the corresponding speakers to play. For example, the vehicle terminal can obtain introductions about the history, culture, stories, etc. of the bridge locally or from a cloud server, and synthesize or play them separately with the navigation instructions.

[0107] In an embodiment of the present application, the audio data application scenario of the vehicle-mounted terminal is determined by parsing the geographic location information and application information of the vehicle-mounted terminal carried in the audio data acquisition request, thereby improving the determination precision and accuracy of the audio data application scenario.

[0108] In an optional implementation, Figure 5 is a flowchart of an optional method for playing audio data provided in an embodiment of the present application, such as Figure 5 As shown, obtaining corresponding in-vehicle audio data according to the above audio data application scenario includes:

[0109] S401, obtaining scene identification information in the audio data application scene, wherein the scene identification information includes at least one of the following: a landscape identification, a geographic coordinate identification, and an environmental feature identification;

[0110] S402: Acquire the in-vehicle audio data corresponding to the scene identification information from an audio resource library.

[0111] Optionally, the audio resource library is set in the vehicle and / or cloud. The audio data files in the audio resource library can be classified according to types such as scenic spots, geographical coordinates, environmental features, etc., and each audio resource can have one or more types.

[0112] In one example, each audio data file in the audio resource library may have a corresponding location coordinate range suitable for playback, or a driving environment suitable for playback, so that the driver can play it when driving to the geographical location or the environment; therefore, what kind of audio resources are obtained from the audio resource library depends on the current location of the vehicle, or the scenic spots, landmarks, surrounding environment features, etc. near the current location.

[0113] As an optional example, by obtaining corresponding vehicle audio data from an audio resource library through scene identification information including various types of information such as cultural landscape identification, geographic coordinate identification, and environmental feature identification, intelligent acquisition of vehicle audio data can be achieved, and the efficiency and accuracy of acquiring vehicle audio data can be improved, thereby improving the matching degree and adaptability of vehicle audio data.

[0114] For example, taking the local processing of the vehicle terminal as an example, when the user drives the vehicle over a historic bridge, the audio data application scenario of the vehicle terminal is determined to be "historical culture". The vehicle terminal obtains the scene identification information in the scene, such as the name of the bridge, geographical coordinates, architectural style, etc., and then the vehicle terminal obtains the corresponding vehicle audio data from the audio resource library based on these scene identification information, such as the introduction of the history, culture, stories, etc. of the bridge, and finally controls the speaker to play these vehicle audio data accordingly.

[0115] It can be understood that the step of obtaining scene identification information in the audio data application scenario improves the efficiency and accuracy of obtaining in-vehicle audio data; compared with other schemes, this method directly obtains the in-vehicle audio data corresponding to the scene identification information from the audio resource library without the need to generate in-vehicle audio data for the audio data application scenario, thereby simplifying the process of obtaining in-vehicle audio data.

[0116] In the embodiment of the present application, scene identification information including various types of information such as cultural landscape identification, geographic coordinate identification, and environmental feature identification is used to obtain corresponding in-vehicle audio data from an audio resource library, thereby realizing intelligent matching of in-vehicle audio data. In addition, different types of in-vehicle audio data can be obtained according to different types of scene identification information, thereby meeting the diverse needs of users.

[0117] In an optional implementation, obtaining corresponding vehicle audio data according to the above audio data application scenario includes:

[0118] S501, acquiring corresponding initial audio data according to the audio data application scenario, wherein the initial audio data at least includes: audio information and spatiotemporal metadata information;

[0119] S502: Generate in-vehicle audio data for the audio data application scenario according to the audio data application scenario, the audio information and the spatiotemporal metadata information.

[0120] In an optional implementation manner, the spatiotemporal metadata information is used to describe the location information and time information of the audio information; the spatiotemporal metadata information is added manually when a user uses an audio production terminal to produce audio information, or is automatically added based on a positioning service.

[0121] Optionally, in the real-time example of the present application, an audio data file may be marked with one spatiotemporal metadata information, or may be separately marked with multiple spatiotemporal metadata. In addition, adaptive adjustments may be made to determine the user's touring location based on the driving location of the user's vehicle.

[0122] In the embodiment of the present application, by generating vehicle audio data for audio data application scenarios according to audio information and spatiotemporal metadata information, intelligent matching of vehicle audio data is achieved. The method can generate vehicle audio data of different types and styles according to different audio information and spatiotemporal metadata information, thereby meeting the diverse needs of users.

[0123] For example, the audio resource library and the audio material library store a panoramic version of the audio data of "Viewing the XX River Scene", which carries the geographic coordinate information of (118.78, 32.05); if the audio resource is needed during vehicle driving, the audio information and the time-space coordinate information contained in the above audio data can be rendered using the current vehicle position, orientation, and nearby scenic spots / landmarks and other location information to present audio with directional characteristics; in one example, the vehicle drives to the south of the XX River and drives west, that is, drives west from (118.74, 32.10) to (118.74, 32.00), and the data of "Viewing the XX River Scene" can be obtained first; if the audio data carries the above-mentioned time-space coordinate information, when controlling the vehicle terminal to play the audio data, a playback method of gradually transitioning from the right front speaker to the right rear speaker can be adopted.

[0124] For example, the steps of obtaining the corresponding initial audio data according to the audio data application scenario and generating vehicle-mounted audio data for the audio data application scenario according to the audio data application scenario, audio information and spatiotemporal metadata information improve the generation efficiency and accuracy of the vehicle-mounted audio data; in addition, due to the method example, the vehicle-mounted audio data corresponding to the scene identification information is not directly obtained from the audio resource library, but the vehicle-mounted audio data for the audio data application scenario is generated, thereby improving the matching degree and adaptability of the vehicle-mounted audio data.

[0125] For example, taking the local processing of the vehicle terminal as an example, when the user drives the vehicle across a historic bridge, the audio data application scenario of the vehicle terminal is determined to be "historical culture". The vehicle terminal obtains the corresponding initial audio data according to the scenario, such as an introduction to the history, culture, and stories of the bridge. The vehicle terminal can also generate vehicle audio data for the scenario based on the scenario, the audio information in the initial audio data, and the spatiotemporal metadata information. For example, different types and styles of vehicle audio data can be generated based on the audio information such as language, tone, rhythm, etc. in the initial audio data, as well as the spatiotemporal metadata information such as the region, time period, and climate where the bridge is located, and then the corresponding speakers on the vehicle are controlled to play these vehicle audio data.

[0126] Therefore, the embodiment of the present application obtains the corresponding initial audio data according to the audio data application scenario, generates vehicle-mounted audio data for the audio data application scenario according to the audio data application scenario, audio information and spatiotemporal metadata information, and realizes intelligent generation of vehicle-mounted audio data, thereby improving the generation efficiency and accuracy of the vehicle-mounted audio data, as well as improving the matching degree and adaptability of the vehicle-mounted audio data.

[0127] In an optional implementation, in response to the audio data acquisition request, determining the audio data application scenario of the vehicle-mounted terminal includes:

[0128] S601, in response to a determination operation of a vehicle driving route, determining all audio data application scenarios related to the vehicle driving route, acquiring vehicle audio data corresponding to all audio data application scenarios, and generating an audio playlist;

[0129] S602, during the driving process of the vehicle, in response to the audio data acquisition request, determining an application scenario of the audio data.

[0130] In the embodiment of the present application, the method determines all audio data application scenarios related to the vehicle's driving route by responding to the determination operation of the vehicle's driving route, thereby obtaining the vehicle audio data corresponding to all audio data application scenarios in advance, and generating an audio playlist, thereby realizing intelligent prediction of vehicle audio data, pre-determining and obtaining audio data application scenarios; the method can obtain all audio data application scenarios related to the user's driving route according to the user's driving route, thereby meeting the user's full-course needs. It is also possible to determine the audio data application scenario in response to an audio data acquisition request during the vehicle's driving process, thereby realizing dynamic determination and update of the audio data application scenario.

[0131] By responding to the operation of determining the vehicle's driving route, the steps of determining all audio data application scenarios related to the vehicle's driving route are performed, thereby improving the efficiency and predictability of obtaining in-vehicle audio data; for example, unlike the other methods mentioned above, not only is the audio data application scenario determined based on the geographic location information and application information of the in-vehicle terminal, but the user can also obtain all audio resources on the driving route at one time and generate a playlist at the beginning of the vehicle's driving route determination; audio resources can also be obtained in real time during driving, thereby improving the accuracy and adaptability of obtaining in-vehicle audio data.

[0132] For example, still taking the local processing of the vehicle terminal as an example, after the user enters the destination in the navigation application, the user sends a confirmation operation of the vehicle's driving route through the locally running navigation application. In response to this operation, the vehicle terminal determines all audio data application scenarios related to the vehicle's driving route, such as "navigation + history and culture", "navigation + natural scenery", "navigation + entertainment and leisure", etc. The vehicle terminal obtains the corresponding vehicle audio data based on these scenarios and generates an audio playlist. When the user is driving the vehicle, the vehicle terminal dynamically determines the audio data application scenario based on the audio data acquisition request sent by the user, and controls the corresponding speakers on the vehicle to play the vehicle audio data.

[0133] Therefore, in the embodiment of the present application, by responding to the determination operation of the vehicle's driving route, all audio data application scenarios related to the vehicle's driving route are determined, so as to obtain the vehicle audio data corresponding to all audio data application scenarios in advance, and generate an audio playlist, thereby improving the acquisition efficiency and predictability of the vehicle audio data. The audio data application scenario can be determined by responding to the audio data acquisition request during the vehicle's driving process, so as to achieve dynamic determination and update of the audio data application scenario, thereby improving the acquisition accuracy and adaptability of the vehicle audio data.

[0134] In an optional implementation manner, if there are multiple in-vehicle audio data, after obtaining the corresponding in-vehicle audio data according to the audio data application scenario, the method further includes:

[0135] S701, displaying an audio play list on a display screen of the vehicle-mounted terminal, wherein the audio play list lists a plurality of the vehicle-mounted audio data;

[0136] S702 , in response to a user's selection operation or confirmation operation on at least one of the in-vehicle audio data, taking the at least one in-vehicle audio data selected or confirmed by the user as the in-vehicle audio data to be played.

[0137] By displaying the audio playlist on the display screen of the vehicle terminal, the user can intuitively understand the content and order of the vehicle audio data, thereby achieving the user's cognition and satisfaction with the vehicle audio data. This method allows the user to select or confirm the vehicle audio data to be played according to his or her preferences and needs, thereby achieving the personalization and customization of the vehicle audio data.

[0138] Compared with other methods, this method does not control the vehicle terminal to play the vehicle audio data according to the vehicle's real-time location information or the target speaker device, but controls the vehicle terminal to play the vehicle audio data according to the user's selection operation or confirmation operation, thereby improving the user's initiative and autonomy over the vehicle audio data.

[0139] For example, still taking the local processing of the vehicle terminal as an example, when the user drives the vehicle across a historic bridge, the vehicle terminal determines all audio data application scenarios related to it, obtains the corresponding vehicle audio data, and generates an audio playlist. The vehicle terminal sends the audio playlist to the vehicle display screen and displays it on the vehicle display screen. The user can see multiple vehicle audio data listed in the audio playlist on the display screen, such as introductions to the history, culture, stories, etc. of the bridge. The user can select or confirm at least one vehicle audio data to be played through a touch screen or voice command. In response to the user's selection operation or confirmation operation, the vehicle terminal uses at least one vehicle audio data selected or confirmed by the user as the vehicle audio data to be played.

[0140] In the embodiment of the present application, by displaying the audio play list on the display screen of the vehicle terminal, in response to the user's selection operation or confirmation operation of at least one vehicle audio data, at least one vehicle audio data selected or confirmed by the user is used as the vehicle audio data to be played, thereby improving the user's selection and control ability of the vehicle audio data. In this way, the user can intuitively understand the content and sequence of the vehicle audio data, thereby improving the user's cognition and satisfaction with the vehicle audio data.

[0141] In an optional implementation, according to the real-time position information of the vehicle, controlling the vehicle-mounted terminal to play the vehicle-mounted audio data accordingly includes:

[0142] S801, determining the environmental characteristics of the environment in which the vehicle-mounted terminal is located according to the real-time location information of the vehicle;

[0143] S802, determining an audio playback style adapted to the above environmental characteristics;

[0144] S803, based on the audio playing style, controlling the vehicle-mounted terminal to play the vehicle-mounted audio data accordingly.

[0145] The embodiment of the present application can play audio of corresponding style or audio preset by the user during driving according to the current position or surrounding environment of the car, which can relieve driving fatigue and improve driving concentration.

[0146] In the embodiment of the present application, the above example can determine the specific environment and regional characteristics of the vehicle terminal according to the real-time location information of the vehicle, thereby obtaining the vehicle audio data that matches it, thereby realizing dynamic matching of the vehicle audio data. It is also possible to obtain different vehicle audio data and audio playback styles related to different environments and regions driven by the user, which can improve the playback effect and user experience of the vehicle audio data, that is, according to the playback style of the vehicle audio data, adjust the volume, sound quality, sound field and other parameters of the vehicle audio data, thereby realizing the optimization and improvement of the playback effect of the vehicle audio data and meeting the diverse needs of users.

[0147] For example, when a user drives a vehicle across a historic bridge, the vehicle terminal determines all audio data application scenarios related to it, obtains the corresponding vehicle audio data, and generates an audio playlist. According to the real-time location information sent by the vehicle terminal, the corresponding matching target speaker device information is determined. For example, if the location of the scenic spot to be introduced is in front of the vehicle, the front speaker can be used; if the location of the scenic spot to be introduced is behind the vehicle, the rear speaker can be used; if the location of the scenic spot to be introduced is around the vehicle, that is, the vehicle is located in the scenic spot, an omnidirectional speaker can be used, etc., to determine the playback style of the vehicle audio data. For example, if the target speaker device is a front speaker, the playback style is "navigation + history and culture"; if the target speaker device is a rear speaker, the playback style is "entertainment and leisure"; if the target speaker device is an omnidirectional speaker, the playback style is "immersive experience". According to these playback styles, the vehicle terminal controls the corresponding speakers on the vehicle to play the vehicle audio data and adjusts its volume, sound quality, sound field and other parameters.

[0148] By adopting the embodiment of the method, the adaptability of the playback style of the in-vehicle audio data and the user satisfaction can be improved, that is, according to the real-time position information of the vehicle of the in-vehicle terminal, the playback style of the in-vehicle audio data that is suitable for it is obtained, thereby meeting the different needs and preferences of users for in-vehicle audio data in different occasions and environments; according to the playback style of the in-vehicle audio data, the user's auditory perception and emotional resonance of the in-vehicle audio data are enhanced, thereby improving the user's cognition and evaluation of the in-vehicle audio data.

[0149] In an optional implementation, according to the real-time position information of the vehicle, controlling the vehicle-mounted terminal to play the vehicle-mounted audio data accordingly includes:

[0150] S901, updating the vehicle audio data played by the vehicle terminal according to the real-time location information of the vehicle; and / or

[0151] S902, controlling the vehicle-mounted terminal to play one or more audio clips of the vehicle-mounted audio data according to the real-time position information of the vehicle.

[0152] In the embodiment of the present application, the vehicle audio data played by the vehicle terminal can be updated according to the real-time location information of the vehicle, for example, the geographic coordinate location information, so that different audio data can be updated and played in real time according to the change of the geographic location information. In addition, the method can also control the vehicle terminal to play one or more audio clips of the vehicle audio data according to the real-time location information of the vehicle.

[0153] In this way, the playback effect and user experience of the in-vehicle audio data can be improved, and the playback effect of the in-vehicle audio data can be optimized and improved to meet the diverse needs of users.

[0154] In an optional implementation, controlling the vehicle-mounted terminal to play the vehicle-mounted audio data accordingly according to the real-time position information of the vehicle includes:

[0155] S1001, determining a target speaker device in the vehicle terminal for playing the vehicle audio data according to the real-time position information of the vehicle;

[0156] S1002, controlling the vehicle-mounted terminal to use the target speaker device to play the vehicle-mounted audio data accordingly.

[0157] Since intuitive sound has a stronger prompting effect than voice, the driver can be assisted in driving by presenting a sound with a sense of direction in the vehicle. For example, if a certain scenic spot is on the right side of the driving road, the broadcast sound here in the sound map APP, the location information of the scenic spot and the current location information of the car are combined. When playing the sound, only the speaker device on the right side is used as the target speaker device to emit sound, so that the driver can make driving judgments more easily.

[0158] By controlling the vehicle terminal to play the vehicle audio data according to the target speaker device of the vehicle terminal, multi-dimensional playback of the vehicle audio data can be achieved, thereby improving the playback effect and user experience of the vehicle audio data.

[0159] In addition, in one example, an embodiment of the present application can also determine the playback order of the vehicle audio data according to the target speaker device of the vehicle terminal, thereby realizing intelligent determination and adjustment of the playback order of the vehicle audio data, thereby improving the rationality of the playback order of the vehicle audio data and user satisfaction.

[0160] In addition, there is an optional example. The embodiment of the present application can also determine the playback style of the vehicle audio data according to the target speaker device of the vehicle terminal, thereby realizing intelligent determination and matching of the playback style of the vehicle audio data, and improving the adaptability and user satisfaction of the playback style of the vehicle audio data.
