Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0049] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0050] Figure 1The flowchart of the vehicle voice interaction method according to an embodiment of the present application is shown. The method can be applied to a terminal device or a server, wherein the terminal device can include but is not limited to one or more of a vehicle terminal, a smart phone, a tablet computer, a portable computer, and a desktop computer; the server can be a physical server or a cloud server.

[0051] like Figure 1 As shown, the vehicle-mounted interaction method at least includes steps S110 to S150, which are described in detail as follows (hereinafter, the method is described by taking the application of the method to a vehicle-mounted terminal as an example, hereinafter referred to as "terminal"):

[0052] In step S110 , a voice input of a target user is received, where the target user is any one of all persons currently in the vehicle.

[0053] In this embodiment, the vehicle terminal can receive the voice input of the target user in real time through its own voice receiving device (such as a microphone). It is worth noting that the target person can be any one of all the people in the current vehicle (such as the driver or a passenger), that is, any person in the current vehicle can perform voice interaction with the vehicle terminal, so that the vehicle terminal can perform voice interaction according to the conversation characteristics of different people in the subsequent process to meet the conversation needs of different people.

[0054] In step S120, recognition is performed based on the voice input to determine the user age, conversation speed and conversation habits of the target user, where the conversation habits are used to characterize the content detail of the target user during the conversation.

[0055] In this embodiment, after receiving the voice input of the target user, the vehicle terminal can perform recognition based on the received voice input, thereby extracting the dialogue features of the target user, which may include the user age, dialogue speed and dialogue habits of the target user, wherein the dialogue habits can be used to characterize the content detail level of the target user during the dialogue. In one example, the content detail level can be divided into three types: concise, medium and detailed. The vehicle terminal can perform recognition and classification based on the voice input of the target user, thereby matching the corresponding type of content detail level for the target user.

[0056] Therefore, by extracting the conversation features of different users and subsequently providing users with a voice interaction experience that is more in line with their personal habits based on the conversation features, the targeted nature of the voice interaction can be ensured and the user experience can be improved.

[0057] In step S130, semantic recognition is performed based on the text information corresponding to the voice input to determine the conversation intention of the target user.

[0058] In this embodiment, the vehicle-mounted terminal can first convert the received voice input into corresponding text information, and perform semantic recognition based on the text information, so as to clarify the conversation intention of the target user, that is, the purpose or demand expressed by the target user during the conversation, such as playing music or map navigation, etc.

[0059] In one example, the vehicle terminal may first determine the keywords in the text information, match the keywords with a predefined list of intent keywords, and determine the target user's conversation intent based on the matching results. In other examples, the vehicle terminal may also use a machine learning algorithm or a deep learning algorithm to identify the text information, thereby determining the target user's conversation intent.

[0060] It should be noted that those skilled in the art may also use other methods to determine the conversation intention, and this application does not specifically limit this.

[0061] In step S140, the corresponding interactive reply content and its playback speed are determined according to the conversation intention, the user age, the conversation speed and the conversation habit.

[0062] In this embodiment, it should be understood that different users may have different conversation requirements during voice interaction. For example, young users who speak concisely and quickly will expect the vehicle terminal to speak quickly and concisely during interaction, while users who speak relatively slowly or children and the elderly will expect the vehicle terminal to speak slowly and with more detailed content during voice interaction. Therefore, after determining the conversation intention of the target user, the vehicle terminal can comprehensively consider the conversation intention, user age, conversation speed and conversation habits of the target user, thereby determining the corresponding interactive reply content and playback speed to achieve targeted voice interaction.

[0063] In step S150, the interactive reply content is voice played according to the playback speed.

[0064] Therefore, based on Figure 1In the embodiment shown, by receiving the voice input of the target user, the target user is any one of all the people in the current vehicle, and performing recognition based on the voice input, the user age, conversation speed and conversation habits of the target user are determined, and the conversation habits are used to characterize the content detail of the target user during the conversation, and semantic recognition is performed based on the text information corresponding to the voice input to determine the conversation intention of the target user, and then, according to the conversation habits, user age, conversation speed and conversation habits, the corresponding interactive reply content and its playback speed are determined, so that the interactive reply content is voice-played according to the playback speed. In this way, the corresponding interactive reply content and playback speed can be determined according to the conversation characteristics of different users, so as to meet the conversation needs of different users and ensure user experience.

[0065] In some embodiments of the present application, determining the corresponding interactive reply content and its playback speed according to the conversation intention, the user age, the conversation speed, and the conversation habit includes:

[0066] Performing a query according to the conversation intention to determine a corresponding plurality of to-be-selected interactive response templates, wherein different to-be-selected interactive response templates correspond to different levels of content detail;

[0067] Determining a target interactive response template from a plurality of interactive response templates to be selected according to the user age, the conversation speed and / or the conversation habit;

[0068] Based on the target interactive reply template, generating corresponding interactive reply content;

[0069] The playback speed corresponding to the interactive reply content is determined according to the user age and / or the conversation speed.

[0070] In this embodiment, a person skilled in the art can preset multiple interactive response templates for each conversation intent, and different interactive response templates corresponding to the same conversation intent have different levels of content details. Therefore, when voice interaction is required, the vehicle terminal can first query according to the conversation intent of the target user, thereby determining multiple interactive response templates corresponding to the conversation intent, and then the vehicle terminal can select one of the multiple interactive response templates as the target interactive response template according to the user's age, conversation speed and / or conversation habits.

[0071] It is worth noting that the in-vehicle terminal can select a target interaction reply template from multiple candidate interaction reply templates based on one or more of the user's age, conversation speed, and conversation habits. In one example, different age groups correspond to interaction reply templates with different levels of content detail. The in-vehicle terminal can make a selection based only on the user's age, and determine the candidate interaction reply template corresponding to the age group of the user as the target interaction reply template; in another example, the in-vehicle terminal can also select a candidate interaction reply template with the corresponding level of content detail from multiple candidate interaction reply templates as the target interaction reply template based on the target user's conversation habits; in yet another example, the in-vehicle terminal can also comprehensively consider any two or three of the user's age, conversation speed, and conversation habits, and then determine the target interaction reply template from multiple candidate interaction reply templates.

[0072] After determining the target interactive reply template, the vehicle terminal can generate the corresponding interactive reply content based on the target interactive reply template. In one example, when the content detail level corresponding to the target interactive reply template is medium or detailed, it can include at least one slot, and the vehicle terminal can extract specific types of keywords (such as place names or music names, etc.) from the text information corresponding to the voice input to fill in the corresponding slots, thereby generating the corresponding interactive reply content. For example, when the target user needs to perform map navigation, keywords used to represent the destination can be extracted from the text information to fill in the target interactive reply template, thereby generating the interactive reply content. When the content detail level corresponding to the target interactive reply template is concise, it may not include a slot, that is, the target interactive reply template is the interactive reply content. For example, when the target user needs to perform map navigation, the target interactive reply template with a concise content detail level can be "Start Navigation" or "Started", etc.

[0073] Next, the in-vehicle terminal can also determine the playback speed of the interactive response content based on the user age and / or conversation speed of the target user. It should be understood that the playback speed is the TTS (Text To Speech) speed, that is, the in-vehicle terminal can convert the interactive response content in text form into corresponding voice for playback according to the playback speed.

[0074] In one example, the vehicle-mounted terminal can determine the playback speed corresponding to the interactive reply content based only on the user's age. Technical personnel in this field can pre-set the corresponding playback speeds for different age groups, so that in actual use, the corresponding playback speed can be queried and determined according to the user's age group.

[0075] In another example, the vehicle-mounted terminal may also directly determine the target user's conversation speed as the playback speed of the interactive reply content, thereby adapting to the target user's conversation needs.

[0076] In some embodiments of the present application, determining a target interactive reply template from a plurality of the candidate interactive reply templates according to the user age, the conversation speed and / or the conversation habit includes:

[0077] Calculating a weighted sum of the user age, the conversation speed, and the conversation habit, and using the weighted sum as an evaluation score;

[0078] According to the numerical range of the evaluation score, a candidate interactive reply template corresponding to the numerical range is selected from the plurality of candidate interactive reply templates as the target interactive reply template.

[0079] In this embodiment, the vehicle terminal can comprehensively consider the user age, conversation speed and conversation habits of the target user to determine the corresponding target interactive reply template. Specifically, those skilled in the art can pre-set the weights corresponding to the user age, conversation speed and conversation habits, and after obtaining the specific values ​​of the three, they can calculate the weighted sum according to the corresponding weights, and use the calculation result as the evaluation score of the target user.

[0080] Technical personnel in this field can predetermine the numerical ranges corresponding to different candidate interactive reply templates. After obtaining the evaluation score of the target user, they can search for the corresponding candidate interactive reply template according to the numerical range of the evaluation score as the target interactive reply template to ensure the accuracy of the determination of the target interactive reply template.

[0081] In some embodiments of the present application, determining the playback speed corresponding to the interactive reply content according to the user age and / or the conversation speed includes:

[0082] If the user age is less than or equal to a first age threshold, obtaining a first preset playback speech speed as the playback speech speed corresponding to the interactive reply content;

[0083] If the user age is greater than or equal to a second age threshold, a second preset playback speed is obtained as the playback speed corresponding to the interactive reply content, and the second age threshold is greater than the first age threshold

[0084] If the user age is greater than the first age threshold and less than the second age threshold, the conversation speaking speed is determined to be the playback speaking speed corresponding to the interactive reply content.

[0085] In this embodiment, the vehicle-mounted terminal can determine the playback speed only based on the user age of the target user. Specifically, technical personnel in this field can pre-set the first age threshold and the second age threshold based on prior experience, and the second age threshold is greater than the first age threshold. For example, the first age threshold may be 13 years old, and the second age threshold may be 60 years old, etc.

[0086] The vehicle-mounted terminal can compare the user's age with the first age threshold and the second age threshold. If the user's age is less than or equal to the first age threshold, it means that the target user is relatively young. The vehicle-mounted terminal can obtain a first preset playback speed as the playback speed corresponding to the interactive reply content. The first preset playback speed can be a playback speed pre-set by technical personnel in this field based on prior experience and suitable for younger users.

[0087] If the user's age is greater than or equal to the second age threshold, it means that the target user is older and speaks faster and may not be heard clearly. Therefore, the in-vehicle terminal can obtain the second preset playback speed as the playback speed of the interactive reply content. Similarly, the second preset playback speed can also be a playback speed pre-set by technical personnel in this field based on prior experience and suitable for older users.

[0088] Furthermore, if the user's age is between the first age threshold and the second age threshold, that is, the user's age is greater than the first age threshold and less than the second age threshold, it means that the vehicle-mounted terminal can directly determine the conversation speed as the playback speed corresponding to the interactive reply content, thereby adapting to the target user's conversation needs and ensuring user experience.

[0089] Based on the foregoing embodiment, in some embodiments of the present application, determining a target interactive reply template from a plurality of the candidate interactive reply templates according to the user age, the conversation speed and / or the conversation habit includes:

[0090] If the user age is less than or equal to the first age threshold, or the user age is greater than or equal to the second age threshold, selecting a candidate interactive reply template with a detailed content detail level from the plurality of candidate interactive reply templates as a target interactive reply template;

[0091] If the user's age is greater than the first age threshold and less than the second age threshold, a candidate interactive response template whose content detail level corresponds to the conversation habit is selected from the plurality of candidate interactive response templates as a target interactive response template.

[0092] In this embodiment, a candidate interaction reply template with detailed content detail level can be used as a target interaction reply template for a target user who is younger (i.e., less than or equal to the first age threshold) or older (i.e., greater than or equal to the second age threshold), thereby providing the target user with more detailed feedback and allowing the target user to clarify his or her own operation behavior.

[0093] For target users of intermediate age (i.e., older than the first age threshold and younger than the second age threshold), the in-vehicle terminal can give responses with corresponding content details based on their own conversation habits, that is, select the candidate interactive response template with content details corresponding to the conversation habits as the target interactive response template, so as to conform to the conversation habits of the target users and ensure user experience.

[0094] In some embodiments of the present application, performing recognition according to the voice input to determine the conversation habits of the target user includes:

[0095] Converting the voice input into corresponding text information;

[0096] Performing word segmentation processing on the text information to obtain at least one keyword;

[0097] The conversation habit of the target user is determined according to the number of keywords corresponding to the target part of speech in at least one of the keywords.

[0098] In this embodiment, when determining the conversation habits of the target user, the vehicle terminal may first convert the target user's voice input into corresponding text information, and segment the text information to obtain at least one keyword. Then, the vehicle terminal may determine the part of speech of each keyword, and determine the number of keywords corresponding to the target part of speech, thereby determining the conversation habits of the target user based on the number.

[0099] In one example, a person skilled in the art may pre-set a first quantity threshold and a second quantity threshold. If the number of keywords of the target part of speech is less than the first quantity threshold, it means that the conversation of the target user is relatively concise, and the corresponding conversation habit can be determined to be concise; if the number of keywords of the target part of speech is greater than or equal to the first quantity threshold and less than or equal to the second quantity threshold, it can be determined that the conversation habit of the target user is medium; if the number of keywords of the target part of speech is greater than the second quantity threshold, it can be determined that the conversation habit of the target user is detailed.

[0100] As a result, the vehicle-mounted terminal can accurately identify the conversation habits of the target user, and then ensure that the subsequent interactive response content is adaptable to the target user, thereby ensuring the user experience.
