[0034] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0035] The content display method provided by the embodiment of the present disclosure can be executed by a vehicle-mounted device, which can be understood as any device with processing and computing capabilities. The device is set in the vehicle cabin and can control the vehicle to perform related operations.

[0036] In order to better understand the inventive concept of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure are described below in conjunction with exemplary embodiments.

[0037] Figure 1 is a flow chart of a content display method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the content display method provided in this embodiment includes the following steps:

[0038] Step 110 : In response to receiving a voice control display instruction from the current user, identifying whether the voice control display instruction contains a content object requested for display and a first title relational word related to the current user to which the content object belongs.

[0039] In an embodiment of the present disclosure, a vehicle-mounted device is installed in the vehicle cabin. The current user can send a voice control display instruction to the vehicle-mounted device. The vehicle-mounted device can receive the voice control display instruction of the current user. In response to receiving the voice control display instruction of the current user, the vehicle-mounted device performs voice recognition on the voice control display instruction to identify whether there is a content object requested for display and a first title relationship word related to the current user to which the content object belongs in the voice control display instruction.

[0040] Specifically, to perform voice recognition on the voice control display instruction, the voice control display instruction can first be subjected to voice activation detection (VAD) to distinguish the human voice signal in the voice control display instruction from various background noise signals, and then the human voice signal can be subjected to automatic speech recognition (ASR) to convert the sentence content in the human voice signal into a natural language signal readable by the vehicle-mounted device, and then the natural language signal can be subjected to natural language understanding (NLU) to identify whether the voice control display instruction contains the content object requested for display and the first title relationship word related to the current user to which the content object belongs.

[0041] Content objects can be understood as statements that represent data content, such as music, video, etc.

[0042] Title-related words can be understood as words with title relationships. For example, title-related words can be family title-related words, and family title-related words can be words such as father, mother, elder brother, younger brother, elder sister, and younger sister.

[0043] For example, when the voice control display instruction is "Play songs my sister has listened to", the current user is "me", the content object is "songs listened to", and the first title relationship word to which the content object "songs listened to" belongs and is related to the current user "me" is "sister".

[0044] Step 120: If the voice control display instruction contains the content object and the first title related word, perform voiceprint recognition on the voice control display instruction to obtain the current voiceprint information of the current user.

[0045] In an embodiment of the present disclosure, when there are content objects and first title-related words in the voice control display instruction, the vehicle-mounted device can perform voiceprint recognition on the voice control display instruction in response to the presence of the content objects and first title-related words in the voice control display instruction to obtain the current voiceprint information of the current user.

[0046] Voiceprint recognition, also known as speaker identification, is a type of biometric technology. It includes both speaker identification and speaker confirmation. Voiceprint recognition converts a speaker's acoustic signals into electrical signals, which are then identified by a computer. Every person has a unique voiceprint, which can be used to determine the speaker's identity.

[0047] Step 130: Search the preset voiceprint map for the current user identifier corresponding to the current voiceprint information, and determine the first user identifier corresponding to the first title relation word of the current user identifier.

[0048] In the disclosed embodiment, a voiceprint map is pre-stored in the vehicle-mounted device. The voiceprint map can include the voiceprint information and user IDs of multiple users, the user ID corresponding to each voiceprint, and the term relationship between any two user IDs. Voiceprint information corresponds one-to-one with user IDs. A user ID can be understood as identification information that uniquely identifies a user.

[0049] For example, user A is a child, user B is user A's father, user A's address to user B is "dad" or "father", and user B's address to user A is "child".

[0050] In an embodiment of the present disclosure, after obtaining the first title relationship word related to the current user and the current voiceprint information of the current user, the vehicle-mounted device can search for the current user identifier corresponding to the current voiceprint information from a preset voiceprint map, and determine the first user identifier corresponding to the first title relationship word of the current user identifier.

[0051] For example, when the voice control display instruction is "Play songs my sister has listened to", where the current user is "me", the content object is "songs listened to", and the first title relationship word to which the content object "songs listened to" belongs and which is related to the current user "me" is "sister", then the vehicle-mounted device can search the preset voiceprint map for the current user ID corresponding to the current voiceprint information of "me", and the first user ID corresponding to the first title relationship word "sister" of the current user ID is the user ID of "my sister".

[0052] Step 140: Extract target data content corresponding to the content object from the data content of the first target user corresponding to the first user identifier.

[0053] In the disclosed embodiment, voiceprint information corresponds one-to-one with user identification, and user identification corresponds one-to-one with users. The vehicle-mounted device stores data content for users corresponding to multiple user identifications. This data content may include data displayed by the user-controlled vehicle-mounted device, such as music and videos played by the user-controlled vehicle-mounted device.

[0054] In the embodiment of the present disclosure, after obtaining the first user identifier, the vehicle device may extract target data content corresponding to the content object from the data content of the first target user corresponding to the first user identifier.

[0055] For example, when the voice control display instruction is "Play songs my sister has listened to", where the current user is "me", the content object is "songs listened to", the first user identifier is the user identifier of "my sister", and the first target user corresponding to the first user identifier is "my sister", the vehicle-mounted device can extract the target data content corresponding to the songs listened to by "my sister" from the data content of "my sister", and the target data content can be the audio data of the songs listened to by "my sister".

[0056] Step 150: Execute a display action of the voice-controlled display instruction on the target data content.

[0057] In the embodiment of the present disclosure, the vehicle-mounted device can execute a display action of a voice-controlled display instruction on the target data content. For example, the display action may include playing, displaying, etc.

[0058] For example, when the voice control display instruction is "Play songs my sister has listened to", after obtaining the target data content corresponding to "Songs my sister has listened to", the vehicle equipment can execute the display action "Play" of the voice control display instruction on the target data content, that is, play songs my sister has listened to.

[0059] In an embodiment of the present disclosure, in response to receiving a voice control display instruction from the current user, the present disclosure identifies whether there is a content object requested for display and a first title relationship word related to the current user to which the content object belongs in the voice control display instruction; if the content object and the first title relationship word exist in the voice control display instruction, the voice control display instruction is subjected to voiceprint recognition to obtain the current voiceprint information of the current user; the current user identifier corresponding to the current voiceprint information is searched from a preset voiceprint map, and the first user identifier corresponding to the first title relationship word of the current user identifier is determined; the target data corresponding to the content object is extracted from the data content of the first target user corresponding to the first user identifier content; the display action of executing voice control display instructions on the target data content can determine the target user based on the current user's voiceprint information and the title relationship word, and then obtain the target data content corresponding to the target user, and then execute the display action of voice control display instructions on the target data content to display the target data content. The user's voiceprint and title relationship can be combined to control the vehicle-mounted device to display or share the data content of other users related to the current user, enriching the control method of the content display of the vehicle-mounted device. The user can interact with the vehicle-mounted device like family or friends, enriching the interaction method between the user and the vehicle-mounted device, improving the convenience of controlling the vehicle-mounted device to display or share content, and improving the user experience.

[0060] In some embodiments of the present disclosure, if the current voiceprint information of the current user does not exist in the preset voiceprint map, the vehicle device may issue a first prompt message, and the first prompt message may include prompting the current user to register the voiceprint.

[0061] And / or, in other embodiments, if the first user identifier does not exist in the preset voiceprint map, the vehicle device may issue a second prompt message, and the second prompt message may include prompting the first target user to register a voiceprint or a user identifier.

[0062] Figure 2 is a flow chart of a content display method provided by an embodiment of the present disclosure, such as Figure 2 As shown, the content display method provided in this embodiment includes the following steps:

[0063] Step 210: In response to receiving the voice control display instruction of the current user, identify whether the voice control display instruction contains a content object requested for display and a first title relation word related to the current user to which the content object belongs.

[0064] Step 220: If the content object and the first title-related word exist in the voice control display instruction, perform voiceprint recognition on the voice control display instruction to obtain the current voiceprint information of the current user.

[0065] Step 230: Search the preset voiceprint map for the current user identifier corresponding to the current voiceprint information, and determine the first user identifier corresponding to the first title relation word of the current user identifier.

[0066] Step 240: Extract target data content corresponding to the content object from the data content of the first target user corresponding to the first user identifier.

[0067] Step 250: Identify whether there is a second title-related word related to the current user before the display action word in the voice control display instruction.

[0068] In the embodiment of the present disclosure, the vehicle-mounted device can identify whether a second title-related word related to the current user exists before the display action word in the voice control display instruction.

[0069] For example, when the voice control display instruction is "Play the songs my sister has listened to to my mother", where the display action word is "play", and the current user is "me", there is a second title relationship word "mom" related to the current user "me" before the display action word "play".

[0070] Step 260: If a second title-related word related to the current user exists before the display action word in the voice control display instruction, search the preset voiceprint map for the second user identifier corresponding to the second title-related word of the current user identifier.

[0071] In an embodiment of the present disclosure, if a second title-related word related to the current user exists before the display action word in the voice control display instruction, the vehicle-mounted device can search for the second user identifier corresponding to the second title-related word of the current user identifier from the preset voiceprint map.

[0072] For example, when the voice control display instruction is "Play the songs my sister has listened to to my mother", and the display action word "play" is preceded by the second title relationship word "mom" related to the current user "me", the vehicle equipment can search for the user identification of "my mother" as the second user identification from the preset voiceprint map.

[0073] Step 270: Identify the target cabin area where the second target user corresponding to the second user identifier is located.

[0074] In the embodiment of the present disclosure, the vehicle-mounted device may identify the target cockpit area where the second target user corresponding to the second user identifier is located.

[0075] In some embodiments, the vehicle-mounted device may obtain audio information sent by the second target user; perform sound source localization on the audio information sent by the second target user to obtain the sound source location of the audio information; and determine the cabin area where the sound source location of the audio information is located as the target cabin area where the second target user is located;

[0076] For example, when the cockpit area where the sound source position of the audio information emitted by the second target user is located is the co-pilot area, it can be determined that the target cockpit area where the second target user corresponding to the second user identifier is located is the co-pilot area.

[0077] In other embodiments, the voiceprint map may also include facial images of the users corresponding to each user ID. The vehicle-mounted device may search the preset voiceprint map for a target facial image corresponding to the second user ID. The vehicle-mounted device may then capture facial images of each user within the cabin area using an image acquisition device within the cabin, identify the similarity between the facial images of each user within the cabin area and the target facial image corresponding to the second user ID, and determine the cabin area containing the users whose facial images have a similarity greater than a preset threshold as the target cabin area for the second target user. The preset threshold can be set as needed and is not limited here.

[0078] Step 280: Execute a display action of the voice-controlled display instruction on the target data content in the target cockpit area.

[0079] In the disclosed embodiment, the vehicle-mounted device may execute a display action of a voice-controlled display instruction on the target data content in the target cockpit area where the second target user is located.

[0080] For example, when the voice control display instruction is "Play songs that my sister has listened to to my mother", the display action word "play" is preceded by the second title relationship word "mom" related to the current user "me", the second user identifier is the user identifier of "my mother", the second target user corresponding to the second user identifier is "my mother", and the target data content is "songs that my sister has listened to". If the target cabin area where "my mother" is located is the co-pilot area, the vehicle equipment can play "songs that my sister has listened to" in the co-pilot area.

[0081] Therefore, the user's voiceprint and title relationship can be combined to control the vehicle equipment to display or share data content of other users related to the current user, enriching the control method of content display of the vehicle equipment. The user can interact with the vehicle equipment like family or friends, enriching the interaction method between the user and the vehicle, improving the convenience of controlling the vehicle equipment to display or share content, and improving the user experience.

[0082] Figure 3 is a flow chart of a content display method provided by an embodiment of the present disclosure, such as Figure 3 As shown, the content display method provided in this embodiment includes the following steps:

[0083] Step 310: In response to receiving a voice control display instruction from the current user, identify whether the voice control display instruction contains a content object requested for display and a first title relational word related to the current user to which the content object belongs.

[0084] Step 320: If the voice control display instruction contains the content object and the first title related word, perform voiceprint recognition on the voice control display instruction to obtain the current voiceprint information of the current user.

[0085] Step 330: Search the preset voiceprint map for the current user identifier corresponding to the current voiceprint information, and determine the first user identifier corresponding to the first title relation word of the current user identifier.

[0086] Step 340: Extract target data content corresponding to the content object from the data content of the first target user corresponding to the first user identifier.

[0087] Step 350: Identify whether each user in the cockpit area has viewing authority for the target data content.

[0088] In the disclosed embodiment, the vehicle device can identify whether each user in the cockpit area has the right to view the target data content. The viewing permission of the data content can be set by the user to whom the data content belongs.

[0089] In some embodiments, identifying whether each user in the cockpit area has viewing permission for the target data content may include steps 3501-3504:

[0090] Step 3501: Obtain user identity information of each user in the cockpit area.

[0091] In the embodiment of the present disclosure, the vehicle-mounted device can obtain the user identity information of each user in the cabin area.

[0092] User identity information can be understood as information that uniquely represents the identity of the user, for example, it can be a term of reference between the user and the current user.

[0093] In some embodiments, obtaining the user identity information of each user in the cockpit area may include S11-S13:

[0094] S11. Acquire the voiceprint information of each user in the cockpit area.

[0095] In some embodiments, the vehicle-mounted device may collect audio information of each user in the cockpit area, and then perform voiceprint recognition on the audio information of each user to obtain the voiceprint information of each user.

[0096] In other embodiments, the vehicle-mounted device may obtain a facial image of each user in the cockpit area; for each user, the voiceprint information corresponding to the user's facial image is searched from a preset voiceprint atlas as the user's voiceprint information.

[0097] S12. Searching for a title relationship word between the user ID corresponding to each user's voiceprint information and the current user ID from a preset voiceprint map.

[0098] S13. Determine the user identity information of each user based on the appellation relationship word between the user's user identifier and the current user identifier.

[0099] Step 3502: Send a permission inquiry instruction to the first target user. The permission inquiry instruction includes user identity information corresponding to each user in the cockpit area to determine whether they have permission to view the target data content.

[0100] In the disclosed embodiment, the permission inquiry instruction may be a voice instruction or a text instruction, which is not limited here.

[0101] In some embodiments, the vehicle-mounted device can identify whether the first target user to whom the target data content belongs is within the cockpit area; when the first target user is within the cockpit area, the vehicle-mounted device can issue a permission inquiry instruction to the first target user; when the first target user is outside the cockpit area, the vehicle-mounted device can establish a communication connection with the first target user's client and then send the permission inquiry instruction to the first target user's client. The client can include a mobile phone, computer, or other device.

[0102] Optionally, to determine whether the first target user to whom the target data content is identified is within the cabin area, the vehicle-machine device may obtain the voiceprint information of each user in the cabin area; if the first voiceprint information of the first target user exists in the voiceprint information of each user, the vehicle-machine device may determine that the first target user is within the cabin area; if the first voiceprint information of the first target user does not exist in the voiceprint information of each user, the vehicle-machine device may determine that the first target user is outside the cabin area.

[0103] Optionally, a target facial image of the first target user is pre-stored in the vehicle-mounted device. To determine whether the first target user, to whom the target data content is identified, is within the cabin area, the vehicle-mounted device may obtain a facial image of each user within the cabin area; if the target facial image of the first target user is present in each user's facial image, the vehicle-mounted device may determine that the first target user is within the cabin area; if the target facial image of the first target user is not present in each user's facial image, the vehicle-mounted device may determine that the first target user is outside the cabin area.

[0104] Step 3503: In response to receiving the permission permission instruction in which the first target user responds to the permission inquiry instruction, determine that each user in the cockpit area has viewing permission for the target data content.

[0105] In the embodiment of the present disclosure, if the first target user is within the cockpit area, when the first target user receives the permission inquiry instruction from the vehicle-mounted device, he can identify whether the user identity information corresponding to each user in the cockpit area has the permission to view the target data content. If the user identity information corresponding to each user in the cockpit area has the permission to view the target data content, the first target user can issue a permission instruction to the vehicle-mounted device. The permission instruction can be a voice instruction or a text instruction, which is not limited here.

[0106] If the first target user is outside the cockpit area, when the client of the first target user receives the permission inquiry instruction from the vehicle-mounted device, the first target user can identify whether the user identity information corresponding to each user in the cockpit area has the permission to view the target data content. If the user identity information corresponding to each user in the cockpit area has the permission to view the target data content, the first target user can control the client to send a permission instruction to the vehicle-mounted device.

[0107] In response to receiving the permission permission instruction in which the first target user responds to the permission inquiry instruction, the vehicle device can determine that each user in the cockpit area has the viewing permission to the target data content.

[0108] Step 3504: In response to receiving the permission prohibition instruction in response to the permission inquiry instruction by the first target user, determine that at least one user in the cockpit area does not have the permission to view the target data content.

[0109] In the embodiment of the present disclosure, if the first target user is within the cockpit area, when the first target user receives the permission inquiry instruction from the vehicle-mounted device, he can identify whether the user identity information corresponding to each user in the cockpit area has the permission to view the target data content. If there is at least one user in the cockpit area who does not have the permission to view the target data content, the first target user can issue a permission prohibition instruction to the vehicle-mounted device. The permission prohibition instruction can be a voice instruction or a text instruction, which is not limited here.

[0110] If the first target user is outside the cockpit area, when the client of the first target user receives the permission inquiry instruction from the vehicle-mounted device, the first target user can identify whether the user identity information corresponding to each user in the cockpit area has the permission to view the target data content. If there is at least one user in the cockpit area who does not have the permission to view the target data content, the first target user can control the client to issue a permission prohibition instruction to the vehicle-mounted device.

[0111] In response to receiving the permission prohibition instruction in which the first target user responds to the permission inquiry instruction, the vehicle device can determine that at least one user in the cockpit area does not have the permission to view the target data content.

[0112] Step 360: When every user in the cockpit area has viewing authority for the target data content, a display action of the voice-controlled display instruction is executed on the target data content.

[0113] Step 370: When at least one user in the cockpit area does not have permission to view the target data content, stop executing the voice control display instruction display action on the target data content and issue a prompt message, which includes the prompt message indicating that the user does not have permission to execute the voice control display instruction display action on the target data content.

[0114] Therefore, the vehicle-mounted device can display the target data content by executing the voice control display instruction only when all users in the cockpit have the viewing authority for the target data content. This can improve the security of content display and protect the user's privacy. The user's voiceprint and title relationship can be combined to control the vehicle-mounted device to display or share the data content of other users related to the current user, enriching the control method of content display of the vehicle-mounted device. The user can interact with the vehicle-mounted device like family or friends, enriching the interaction method between the user and the vehicle-mounted device, improving the convenience of controlling the vehicle-mounted device to display or share content, and improving the user experience.

[0115] In some embodiments of the present disclosure, before searching for the current user identifier corresponding to the current voiceprint information from the preset voiceprint map and determining the first user identifier corresponding to the first appellation relation word of the current user identifier, the vehicle device may construct a voiceprint map, which may be specifically Figure 4 A flowchart of a voiceprint map construction method is provided, such as Figure 4 As shown, the voiceprint map construction method provided in this embodiment includes the following steps:

[0116] Step 410: Acquire the voiceprint information of multiple users and the user identification corresponding to each voiceprint information.

[0117] In the disclosed embodiment, the vehicle-mounted device may obtain the voiceprint information of multiple users and the user identification corresponding to each voiceprint information.

[0118] In some embodiments, obtaining voiceprint information of multiple users may include steps 4101-4102:

[0119] Step 4101: For each of the multiple users, collect the audio sentences uttered by the user.

[0120] In the disclosed embodiment, the vehicle-mounted device may collect audio sentences uttered by each of a plurality of users.

[0121] In some embodiments, collecting an audio sentence uttered by a user may include S21-S22:

[0122] S21 . In response to receiving a voiceprint registration voice instruction, identifying a target sound zone where the voiceprint registration voice instruction is located.

[0123] In the embodiment of the present disclosure, the vehicle cabin includes multiple sound zones, such as the main driver's sound zone, the co-driver's sound zone, the rear sound zone, etc. The sound zone can be understood as the range in which the microphone receives sound.

[0124] When voiceprint registration is required, the user or other users other than the user can issue a voiceprint registration voice command. The vehicle equipment can respond to receiving the voiceprint registration voice command, identify the target microphone that receives the voiceprint registration voice command, and determine the sound zone corresponding to the target microphone as the target sound zone where the voiceprint registration voice command is located.

[0125] S22. Collecting audio sentences uttered by the user from the target sound zone.

[0126] In the embodiment of the present disclosure, the vehicle-mounted device can collect audio sentences uttered by the user from the target sound zone.

[0127] In some other embodiments, collecting audio sentences uttered by the user includes S31-S33:

[0128] S31. In response to receiving a selection operation for a voiceprint registration zone, taking the zone determined by the selection operation as a target zone for voiceprint registration.

[0129] In an embodiment of the present disclosure, when voiceprint registration is required, the user or another user other than the user can select a voice zone for voiceprint registration in the voiceprint registration interface displayed by the vehicle-mounted device, for example, by clicking on a voice zone selection option. In response to receiving the voiceprint registration voice zone selection operation, the vehicle-mounted device can use the voice zone determined by the selection operation as the target voice zone for voiceprint registration. For example, if the voice zone determined by the selection operation is the passenger seat voice zone, the target voice zone for voiceprint registration is the passenger seat voice zone.

[0130] S32: Collecting audio sentences uttered by the user from the target sound zone.

[0131] This can improve the convenience of voiceprint registration and enhance user experience.

[0132] Step 4102: Perform voiceprint recognition on audio sentences that meet preset requirements to obtain voiceprint information of each user. The preset requirements include at least one of the following: the audio sentence is a preset sentence, the number of audio sentences is greater than a preset number, and the audio quality of the audio sentence is greater than a preset audio quality.

[0133] In the disclosed embodiment, the vehicle-mounted device can detect whether the audio sentences issued by the user meet the preset requirements, perform voiceprint recognition on the audio sentences that meet the preset requirements, and obtain the voiceprint information of each user.

[0134] If the audio sentence does not meet the preset requirements, the vehicle equipment can stop performing voiceprint recognition on the audio sentence and issue a prompt message indicating that the audio sentence cannot be recognized and needs to be re-entered.

[0135] The preset requirements may include at least one of the following: the audio sentence is a preset sentence, the number of audio sentences is greater than a preset number, and the audio quality of the audio sentence is greater than a preset audio quality.

[0136] The preset statement can be set as needed, such as "Hello, car computer classmate", there is no limitation here.

[0137] The preset number can be set as needed, for example, 3, which is not limited here.

[0138] The preset audio quality may include that the amount of noise contained in the audio sentence is less than a preset noise amount, the volume of the audio sentence is greater than a preset volume, etc.

[0139] By setting preset requirements, you can ensure that the acquired audio sentences are clear and improve the accuracy of voiceprint recognition.

[0140] In some embodiments, if the audio sentence does not meet the preset requirements, it is determined that the user's voiceprint registration has failed, and the user is prompted to perform the voiceprint registration operation again;

[0141] When the number of voiceprint registration failures is greater than a preset number, it is determined that the user's voiceprint registration has failed.

[0142] The preset number of times can be set as needed, for example, 3 times, which is not limited here.

[0143] Step 420: Obtain the appellation relation words between the user identifiers corresponding to any two voiceprint information in the voiceprint information of multiple users.

[0144] In the embodiment of the present disclosure, the vehicle-mounted device can obtain the appellation relationship words between the user identifiers corresponding to any two voiceprint information of multiple users.

[0145] In some embodiments, obtaining the appellation relationship word between user identifiers corresponding to any two voiceprint information of multiple users may include steps 4201-4203:

[0146] Step 4201: Select any user ID from multiple user IDs as a source user ID.

[0147] Step 4202: In response to the operation of determining the title relationship term of each remaining user identifier other than the source user identifier in the multiple user identifiers relative to the source user identifier, obtain the title relationship term of each remaining user identifier relative to the source user identifier.

[0148] In an embodiment of the present disclosure, a user can perform a determination operation on the voiceprint map construction interface of the vehicle-mounted device for the title relationship words of each remaining user identifier other than the source user identifier in multiple user identifiers relative to the source user identifier, for example, an operation such as clicking on the title relationship words of the remaining user identifiers relative to the source user identifier. The vehicle-mounted device can obtain the title relationship words of each remaining user identifier relative to the source user identifier in response to the determination operation on the title relationship words of each remaining user identifier other than the source user identifier in multiple user identifiers relative to the source user identifier.

[0149] For example, user ID A can be selected as the source user ID. Based on the determination operation of the title terms of the remaining user IDs B relative to the source user ID, it can be determined that the title relationship term of the remaining user IDs B relative to user ID A is "father".

[0150] Step 4203: Perform relational reasoning based on the title relation words of each remaining user identifier relative to the source user identifier to obtain the title relation words between any two user identifiers.

[0151] In the embodiment of the present disclosure, the vehicle-mounted device may perform relational reasoning based on the title relational terms of each remaining user identifier relative to the source user identifier to obtain the title relational terms between any two user identifiers.

[0152] For example, user ID A is the source user ID. Based on the determination operation of the appellation relationship words of the remaining user IDs other than the source user ID relative to the source user ID, it can be determined that the remaining user ID B is the father of user ID A, and the remaining user ID C is the child of user ID A. Then the vehicle-mounted device can infer that the remaining user ID B is the grandfather of the remaining user ID C.

[0153] Step 430: Construct a voiceprint graph based on the voiceprint information of multiple users and the target title relationship words between the user identifiers corresponding to any two voiceprint information.

[0154] In the disclosed embodiment, the vehicle-mounted device can construct a voiceprint map based on the voiceprint information of multiple users and the target title relationship words between the user identifiers corresponding to any two voiceprint information, and save the voiceprint map to a local or cloud server.

[0155] In some embodiments, in addition to including the voiceprint information of multiple users and the appellation relationship terms between the user identifiers corresponding to any two voiceprint information, the voiceprint map may also include the facial image of the user corresponding to each user's voiceprint information. The vehicle-mounted device may capture the user's facial image using an image capture device in the cabin.

[0156] Image acquisition devices may include cameras, etc.

[0157] In this way, a voiceprint map can be quickly constructed so that the vehicle equipment can determine the relationship between users and the identity of the users based on the voiceprint map and the users' voiceprints.

[0158] For example, Figure 5 is a schematic diagram of a method for constructing a voiceprint map provided by an embodiment of the present disclosure, such as Figure 5 As shown, in the voiceprint map construction interface 500, the map administrator is the source user, the map administrator's user ID is D, and the current user's user ID is E. The user can determine the appellation relationship between user ID E and the map administrator's user ID D. The user selects "father" as the appellation relationship between user ID E and user ID D, and then clicks the OK option. The vehicle-mounted device responds to the appellation relationship determination operation and determines that the appellation relationship between user ID E and the administrator's user ID D is "father," meaning that the user entering the account is the administrator's father. The vehicle-mounted device then extracts the voiceprint information of the entering user and the map administrator from a preset voiceprint list to construct a voiceprint map 510. The voiceprint map 510 may include the voiceprint information of the entering user and the map administrator, as well as the appellation relationship between user ID E and user ID D. If the voiceprint map is constructed successfully, the user can click the Finish option to end the entry, or click the Continue entry option to proceed to the next user's entry. If the voiceprint map construction fails, the user can click the Re-enter option to re-enter the account.
