[0018] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description. It should be noted that the embodiments in the present disclosure and the features in the embodiments may be combined with each other without conflict.

[0019] It should be pointed out that in the technical solutions disclosed herein, the collection, acquisition, storage, processing, transmission, provision, disclosure and application of user personal information (such as contact information, etc.) are all carried out with the user's knowledge and explicit authorization, comply with the relevant laws and regulations, and do not violate public order and good morals.

[0020] Figure 1 An exemplary system architecture 100 is shown to which embodiments of the dialing method, dialing device, electronic device, non-transitory computer-readable storage medium, and computer program product of the present disclosure can be applied.

[0021] like Figure 1 As shown, the system architecture 100 may include terminal devices 101, 102, 103, a network 104 and a vehicle 105. The network 104 is used to provide a medium for a communication link between the terminal devices 101, 102, 103 and the vehicle 105. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc. Among them, in some implementations of the embodiments of the present disclosure, the terminal devices 101, 102, 103 may be connected to the vehicle-mounted telematics processor (Telematics BOX, T-BOX) of the vehicle 105 (not shown in the figure) through the network 104, and further, the vehicle-mounted T-BOX may be connected to the vehicle-mounted computer (not shown in the figure) of the vehicle 105 through the communication connection, and the vehicle-mounted T-BOX communicates with the vehicle-mounted computer through the controller area network bus (Controller Area Network BUS, CAN-BUS) to realize the transmission of instructions and information.

[0022] The user can use the terminal devices 101, 102, 103 to interact with the vehicle 105 through the network 104 to receive or send messages, etc. The terminal devices 101, 102, 103 and the vehicle 105 can be installed with various applications for realizing information communication between the two, such as near field communication applications, wireless communication applications, etc.

[0023] The terminal devices 101, 102, 103 may be hardware or software. When the terminal devices 101, 102, 103 are hardware, they may be various electronic devices with display screens, including but not limited to smart phones, tablet computers, laptop computers, and desktop computers, etc.; when the terminal devices 101, 102, 103 are software, they may be installed in the electronic devices listed above, and they may be implemented as multiple software or software modules, or as a single software or software module, which is not specifically limited here.

[0024] The vehicle computer of vehicle 105 can provide various services through various built-in applications. Taking the dialing application as an example, the vehicle computer of vehicle 105 can achieve the following effects when running the dialing application: it can accurately extract voiceprint feature information and semantic information after receiving the voice command, so as to accurately match the target contact information corresponding to the voice command from the contact information that has been pre-synchronized and stored locally in the vehicle based on the voiceprint feature information and semantic information, so that there is no need to access the mobile terminal device held by the first user to lock the target contact information for dialing operation. In other words, the dialing operation can be initiated based on the contact information stored locally in the vehicle, and there is no need to always maintain the communication connection between the mobile terminal device held by the first user and the vehicle. This can improve the efficiency of dialing and enhance the intelligent interaction experience with the vehicle.

[0025] It should be understood that Figure 1 The number of terminal devices, networks and vehicles in the embodiment is only for illustration. Any number of terminal devices, networks and vehicles may be provided as required.

[0026] At present, in some scenarios, each time a vehicle-mounted device (such as a Bluetooth vehicle-mounted device) is used to connect to a mobile terminal device (such as terminal devices 101, 102, 103), the contact information and call records can be synchronized to the phone application on the vehicle through the Phone Book Access Profile (PBAP), wherein PBAP is a standard for accessing phone book information in the Bluetooth protocol, which allows one device (such as a hands-free device or other Bluetooth device set in the vehicle 105) to access the phone book, call records and other information of another device (such as terminal devices 101, 102, 103). When a large amount of contact information (such as multiple phone numbers, email addresses, etc.) contained in the phone book of the mobile terminal device needs to be synchronized to the vehicle, the increase in the amount of transmitted data will require a longer time to display the contact information on the vehicle, thereby affecting the efficiency of the dialing operation based on this, and it is usually necessary to use the Bluetooth phone to initiate a call to the contacts in the address book of the mobile terminal device when the mobile terminal device is in communication with the vehicle. In view of this situation, it is necessary to provide a dialing solution that can improve the efficiency of dialing and enhance the intelligent interaction experience with the vehicle.

[0027] Please refer to the following Figure 2 , Figure 2 A flowchart of a dialing method provided in an embodiment of the present disclosure can be applied to a vehicle, wherein the process 200 includes the following steps:

[0028] Step 201: In response to receiving a voice instruction, extract voiceprint feature information and semantic information in the voice instruction.

[0029] This step is intended to be performed by the execution subject of the dialing method (such as Figure 1 The vehicle computer in the vehicle 105 shown in the figure can realize the effective recognition and reception of the real-time voices uttered by the passengers in the vehicle, for example, it can receive the voices through a microphone arranged in the vehicle, and extract the voiceprint feature information and semantic information of the received voice commands, for example, it can process the received voice commands through the corresponding voiceprint feature extraction model and semantic recognition model; wherein, the voiceprint feature information can be used to distinguish different passengers, and the semantic information can be used to represent the content of the voice commands.

[0030] Step 202: Determine target contact information from the contact information stored locally in the vehicle based on the voiceprint feature information and semantic information; wherein the contact information stored locally in the vehicle is pre-synchronized with the contact information stored in the mobile terminal device held by the first user.

[0031] Based on step 201, this step is intended to allow the above-mentioned execution subject to pre-synchronize and store the contact information stored in the mobile terminal device (such as the above-mentioned terminal devices 101, 102, 103) held by the first user to the local vehicle, and to quickly and accurately match the corresponding target contact information from the contact information stored locally in the vehicle based on the voiceprint feature information and semantic information extracted from the received voice command. The mobile terminal device held by the first user may be a device that has established a communication connection with the vehicle, and the contact information stored therein may be pre-synchronized and stored locally in the vehicle when the communication connection can be established.

[0032] Step 203: Perform a dialing operation according to the target contact information.

[0033] On the basis of step 202, this step is intended for the execution subject to perform a dialing operation based on the target contact information matched from the contact information locally stored in the vehicle according to the voice command.

[0034] The dialing method provided by the embodiment of the present disclosure can accurately extract voiceprint feature information and semantic information of the received voice command, so as to accurately match the target contact information corresponding to the voice command from the contact information that has been pre-synchronized and stored locally in the vehicle based on the voiceprint feature information and semantic information, thereby eliminating the need to access the mobile terminal device held by the first user to lock the target contact information for dialing operations. In other words, a dialing operation can be initiated based on the contact information stored locally in the vehicle without always maintaining a communication connection between the mobile terminal device held by the first user and the vehicle, thereby improving the efficiency of dialing and enhancing the intelligent interaction experience with the vehicle.

[0035] Please refer to Figure 3 , Figure 3 A flowchart of another dialing method provided by an embodiment of the present disclosure, wherein process 300 includes the following steps:

[0036] Step 301: In response to receiving a voice instruction, extract voiceprint feature information and semantic information in the voice instruction.

[0037] Wherein, the step 301 is similar to the step Figure 2 The same as step 201 shown, please refer to the corresponding part of the previous embodiment for the same content, and will not be repeated here. Further, the target contact information for performing the dialing operation can be determined from the contact information stored locally in the vehicle through the following steps 302-303 according to the voiceprint feature information and semantic information extracted in the above step 301.

[0038] Step 302: Determine a first identity relationship between a first user and a second user indicated by voiceprint feature information; wherein the contact information stored locally in the vehicle is pre-synchronized with the contact information stored in a mobile terminal device held by the first user.

[0039] Step 303: Determine the contact information that matches the semantic information and the first identity relationship in the contact information stored locally in the vehicle as the target contact information.

[0040] In this embodiment, the first identity relationship between the first user holding the mobile terminal device and the second user indicated by the voiceprint feature information in the received voice command can be determined first, and then the contact information that matches the first identity relationship and the semantic information extracted from the voice command can be screened out from the contact information stored locally in the vehicle, and then the screened contact information can be determined as the target contact information for performing the dialing operation. In other words, by pre-establishing or setting the identity relationship between different users, and the corresponding relationship between the identity relationship and the stored contact information, and further combining the semantic information corresponding to the voice command received in real time, the target contact information that matches the voice command can be accurately obtained.

[0041] In some optional implementations of the disclosed embodiments, the first identity relationship between the first user and the second user may include a generational relationship; and the voiceprint feature information of the second user is pre-collected and stored locally in the vehicle, and further, the corresponding relationship between the second user and its voiceprint feature information, and the first identity relationship between the first user and the second user indicated by the voiceprint feature information may be pre-established and stored. It should be noted that in this embodiment, the stored relationship may be adjusted or a new relationship may be added in response to a received update instruction to apply to more application scenarios.

[0042] In some specific application scenarios, the generation relationship between the first user and the second user may include but is not limited to the father-daughter relationship, the father-son relationship, the grandfather-grandson relationship, the uncle-nephew relationship, the uncle-nephew relationship, etc. In a specific embodiment, the user A (corresponding to the first user) may be the owner of the vehicle or the current driver. The contact information stored in the mobile terminal device held by the user A has been synchronized to the vehicle computer through PBAP in advance and stored locally in the vehicle. When the user B (corresponding to the second user) who rides with the user A issues a voice command, such as "call mom", the voiceprint feature information and semantic information can be extracted. The user B can be identified as a child through the voiceprint feature information, and the extracted semantic information can be "mom". The user B indicated by the voiceprint feature information and the parent-child relationship between the user A and the user B (corresponding to the first identity relationship) can be determined based on the voiceprint feature information. Further, based on the parent-child relationship and the semantic information "mom", the corresponding target contact information can be determined from the contact information stored locally in the vehicle, and the corresponding dialing operation is performed based on the phone application in the vehicle computer.

[0043] Please refer to Figure 4 , Figure 4 A flowchart of another dialing method provided by an embodiment of the present disclosure, wherein process 400 includes the following steps:

[0044] Step 401: In response to receiving a voice instruction, extract voiceprint feature information and semantic information in the voice instruction.

[0045] Step 402: Determine a first identity relationship between a first user and a second user indicated by voiceprint feature information; wherein the contact information stored locally in the vehicle is pre-synchronized with the contact information stored in a mobile terminal device held by the first user.

[0046] Among them, the steps 401-402 are similar to the steps Figure 3 The steps 301-302 shown are the same, and the same contents can be referred to the corresponding parts of the previous embodiment, which will not be described again. Further, the contact information matching the semantic information and the first identity relationship in the contact information stored locally in the vehicle can be determined as the target contact information through the following steps 403-405.

[0047] Step 403: Determine a second identity relationship matching the first identity relationship according to the semantic information.

[0048] Step 404: Determine a third user having a second identity relationship with the first user from among the users indicated by the contact information stored locally in the vehicle.

[0049] Step 405: Determine the contact information of the third user as the target contact information.

[0050] In this embodiment, after extracting the semantic information in the voice command and determining the first identity relationship between the first user holding the mobile terminal device and the second user indicated by the voiceprint feature information in the received voice command, another identity relationship matching the first identity relationship, namely the second identity relationship, can be further determined based on the semantic information, and a third user having the second identity relationship with the first user can be screened out from the users indicated by the contact information stored locally in the vehicle, so as to determine the contact information corresponding to the third user as the target contact information for performing the dialing operation. In other words, by pre-establishing or setting the identity relationship between different users, the corresponding relationship between the identity relationship and the stored contact information, and associating different identity relationships based on the corresponding semantics, the target contact information matching the voice command can be accurately obtained.

[0051] In some optional implementations of the disclosed embodiments, the second identity relationship between the first user and the third user may include but is not limited to a generational relationship, a kinship relationship (such as a husband-wife relationship, a brotherly relationship, a sisterly relationship, etc.), a friend relationship, a colleague relationship, etc.; and the voiceprint feature information of the second user is pre-collected and stored locally in the vehicle, and further, a corresponding relationship between the second user and his voiceprint feature information, a first identity relationship between the first user and the second user indicated by the voiceprint feature information, and different identity relationships may be pre-established and stored, and different identity relationships may be associated and stored based on corresponding semantics. It should be noted that in this embodiment, the stored relationships may be adjusted or new relationships may be added in response to the received update instructions to apply to more application scenarios.

[0052] Continuing with the above specific application scenario as an example, after extracting the voiceprint feature information and semantic information "Mom" in the voice command "Call Mom", and identifying user B as a child based on the voiceprint feature information, and determining that user A and user B are in a father-son relationship (corresponding to the first identity relationship), the husband-wife relationship that matches the father-son relationship can also be determined based on the semantic information "Mom" (corresponding to the second identity relationship), and further, user C who has the husband-wife relationship with user A can be determined from the contact information stored locally in the vehicle, so as to determine the contact information of user C as the target contact information, and then perform the dialing operation for user C based on the telephone application in the vehicle computer.

[0053] In some optional implementations of the embodiments of the present disclosure, the above-mentioned candidate contact information may be contact information containing the semantic information; for example, the name of the user indicated by the candidate contact information may include the semantic information; for example, the remark information or nickname information corresponding to the user indicated by the candidate contact information may include the semantic information.

[0054] In some optional implementations of the embodiments of the present disclosure, in the above Figure 4 Based on the corresponding dialing method embodiment, the above step 404 can be further executed as follows: obtaining candidate contact information matching the semantic information from the contact information stored locally in the vehicle; determining a third user having a second identity relationship with the first user from the users indicated by the candidate contact information.

[0055] In this embodiment, in order to improve the efficiency and accuracy of screening the target contact information, the scope of the contact information used to determine the target contact information can be first narrowed down by using the semantic information proposed from the received voice command, and then the third user with whom the first user has a corresponding identity relationship, i.e., the second identity relationship, can be finally determined from the users indicated by the candidate contact information screened based on the semantic information.

[0056] Continuing with the above specific application scenario as an example, when the semantic information "Mom" in the voice command is extracted, contact information with a name stored as "Mom" or a note (or nickname) marked as "Mom" can be filtered out from the contact information stored locally in the vehicle, and then user C who has a husband and wife relationship with user A can be filtered out.

[0057] In some optional implementations of the embodiments of the present disclosure, in the above Figure 2 , Figure 3 or Figure 4 Based on the corresponding dialing method embodiment, the above step 201, step 301 or step 401 can be further executed as follows: in response to receiving a voice command and detecting that the second user is located in the passenger position of the vehicle, extracting voiceprint feature information and semantic information.

[0058] This embodiment can be applicable to the scenario where the voice command is issued by a user who is not sitting in the driving seat of the vehicle. That is, when it is determined that the received voice command is issued by a user located in the passenger seat of the vehicle, the operation of extracting the voiceprint feature information and semantic information in the voice command is performed. In this way, while improving the smart dialing experience of the passengers in the vehicle, the driving safety can be ensured by avoiding responding to the dialing voice from the user in the driving seat.

[0059] In some optional implementations of the disclosed embodiments, the second user who issued the voice command can be determined to be located in the passenger position of the vehicle in response to the received voice command being collected by a sound receiving device (such as a microphone) disposed near the passenger position of the vehicle (such as the backrest of the seat corresponding to the main driver's seat and the co-driver's seat). It should be noted that other detection methods can also be used to determine whether the user who issued the voice command is located in the passenger position of the vehicle, which is not specifically limited here.

[0060] In some optional implementations of the embodiments of the present disclosure, in the above Figure 2 , Figure 3 or Figure 4 On the basis of the corresponding dialing method embodiment, the contact information stored locally in the vehicle includes contact information belonging to a preset group stored in the mobile terminal device; and the dialing method may further include the following contents:

[0061] In response to the mobile terminal device and the vehicle-mounted device establishing a communication connection for the first time, the contact information belonging to the preset group is stored in the vehicle-mounted device; in response to the mobile terminal device and the vehicle-mounted device establishing a communication connection again and the contact information belonging to the preset group is updated, the contact information stored in the vehicle-mounted device is updated based on the updated contact information belonging to the preset group.

[0062] In this embodiment, only part of the contact information of the mobile terminal device held by the first user, that is, the contact information belonging to the preset group, can be pre-synchronized to the vehicle for local storage, wherein the contact information belonging to the preset group can be selected and set according to the specific needs of the user, so that while improving the user experience, it can avoid excessive occupation of the vehicle's local storage space or resources. Furthermore, in the embodiment of the present disclosure, specifically when the mobile terminal device held by the first user first establishes a communication connection with the vehicle's onboard device (such as a car computer) for the first time, the contact information belonging to the preset group stored therein can be synchronized to the onboard device for storage, so that it can be called locally at any time later, without the need to synchronize the stored contact information from the mobile terminal device side every time a dialing operation is performed, thereby improving the dialing efficiency.

[0063] Furthermore, when the mobile terminal device subsequently re-establishes a communication connection with the vehicle's onboard device, and detects that the contact information belonging to the preset group stored on the mobile terminal device side has been updated, for example, by comparing the contact information stored on both ends and finding a difference, the updated contact information on the mobile terminal device side can be promptly synchronized and stored in the vehicle locally to ensure that the target contact information can be retrieved based on the latest contact information to perform a dialing operation in response to the user's voice command. Among them, when updating the contact information stored in the onboard device based on the updated contact information belonging to the preset group, all the contact information belonging to the preset group can be synchronized and updated to the vehicle locally to cover the previously stored contact information, which is simple and convenient to operate; or only the part of the contact information belonging to the preset group that has changed can be synchronized and updated to the vehicle locally to increment, decrement or change the contact information previously stored in the vehicle locally, so that the update efficiency can be ensured. It should be noted that the specific update method can be determined according to specific needs and is not specifically limited here.

[0064] In some other optional implementations of the embodiments of the present disclosure, the contact information stored locally in the vehicle may include all contact information stored in the mobile terminal device, that is, all contact information stored on the mobile terminal device side may be synchronously stored locally in the vehicle to meet more diverse dialing requirements; and the dialing method may further include the following contents:

[0065] In response to the mobile terminal device establishing a communication connection with the vehicle's onboard device for the first time, all the contact information is stored in the onboard device; and in response to the mobile terminal device establishing a communication connection with the vehicle-mounted device again and all the contact information is updated, the contact information stored in the onboard device is updated based on all the updated contact information.

[0066] Furthermore, after all the contact information stored in the mobile terminal device is synchronously stored locally in the vehicle, the dialing method may also include the following: in response to receiving a grouping instruction, part of all the contact information is divided into preset groups, and the identity relationship between the contact information and the first user corresponding to the mobile terminal device, such as a generation relationship, may be further set to achieve sorting of the contact information in the preset group. Specifically, the grouping can be flexibly set according to specific needs. In this way, by processing the synchronously stored dead data, the processed data can be more dynamic and better adapted to the smart cockpit.

[0067] In some optional implementations of the embodiments of the present disclosure, the above-mentioned preset groups can be flexibly set by the user according to specific needs. In some embodiments, they can be groups of contacts who have close relationships with the above-mentioned first user such as relatives, or they can also be groups of the first user's frequently used contacts and / or recent contacts.

[0068] For example, the contact information in the preset group indicates a user who has a close relationship with the first user, and the first user is the owner of the vehicle. For passengers sitting in the back seat, such as the child of the owner, when the owner is driving and his mobile phone is used for navigation but not connected to the car computer or the mobile phone is not brought to the car, and the child in the back seat wants to make a call to other family members, at this time, after the close contacts are synchronously stored, the child in the back seat can directly dial and communicate through the close contacts saved on the car computer through the screen set at the corresponding position of the back seat or the back seat voice device, in order to avoid directly showing the stored contact address book to the child and causing him to Lack of knowledge leads to confusion about contact notes. For example, if the names of "wife" and "mother" are stored in the contact information of the car owner, when the contact information is shown to a child, the child may think that the "mother" here is his own mother, which results in the inability to dial correctly. In the implementation method of the disclosed embodiment, the phone call can be dialed according to the set generation relationship. For example, if the voice output by the child is "call mom", the car system will automatically broadcast the phone number of the car owner's "wife" instead of the phone number stored as the car owner's "mother". In this way, dialing is changed from relying on the Bluetooth phone on the car computer to dialing through the car computer itself, realizing more intelligent interaction. The car is given its own life and more autonomous functions. The data is connected and saved through the association of accounts, and dialing is performed using the system built into the car control. The three ends are connected, from the mobile phone to the car control, to the back seat, and then dialed out. The phone call that is dialed by relying on Bluetooth is changed to the active car computer to make the call.

[0069] In some optional implementations of the embodiments of the present disclosure, the contact information involved in the above embodiments may include address book information and / or call record information.

[0070] In some optional implementations of the embodiments of the present disclosure, there may be multiple first users. Considering that the Bluetooth Multimedia Access Control (MAC) addresses or Bluetooth device addresses of mobile terminal devices held by different users are different, the contact information that has been synchronized and stored can be stored locally in the vehicle in the form of a table, and each first user and its corresponding contact information can be associated and stored, so that after the first user passes the authentication, the contact data of the current first user can be automatically synchronized and displayed, for example, through a display device set at a corresponding position in the rear row of the vehicle, so that the rear passengers can directly use the corresponding device in the rear row to implement quick dialing.

[0071] In some optional implementations of the embodiments of the present disclosure, when the dialing operation is performed according to the target contact information, the dialing can be performed through the vehicle's onboard device (or car computer) through the T-BOX or directly through the vehicle's onboard device (or car computer).

[0072] In some optional implementations of the embodiments of the present disclosure, in response to the successful startup of the vehicle's on-board device and the authentication of the first user is passed and the PBAP permission is obtained, the contact information stored locally in the vehicle can be retrieved from the database for display, such as on a car computer set near the driver's seat of the vehicle, or on a display device set on the backrest of the driver's seat or passenger seat.

[0073] In some optional implementations of the embodiments of the present disclosure, in response to receiving a voice command, data (such as contact information) can be acquired from the background based on the PBAP protocol to achieve a quick response.

[0074] Further references Figure 5 As an implementation of the methods shown in the above figures, the present disclosure provides an embodiment of a dialing device, which is at least Figure 2-4 Corresponding to the method embodiment shown, the dialing device can be specifically applied to various electronic devices (for example, vehicle-mounted electronic devices or vehicle-mounted devices).
