Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is an application scenario schematic diagram of a voice interaction method according to an embodiment of the present application. As shown in fig. 1, the in-vehicle apparatus 101 has a voice function to perform voice interaction with a user. The voice input by the user can be recognized by the in-vehicle apparatus 101 and subjected to subsequent interactive logic processing. Alternatively, the in-vehicle apparatus 101 may also be connected to the server apparatus 102, and the server apparatus 102 may communicate with the in-vehicle apparatus 101 in various ways. The server device 102 is, for example, a cloud control platform, a vehicle-road cooperative management platform, a central subsystem, an edge computing platform, a cloud computing platform, or the like. The in-vehicle device 101 may transmit the recognized user voice to the server device 102, and the server device 102 performs subsequent interactive logic processing.
When the user uses the voice interaction function, taking idiom receiving as an example, the vehicle-mounted device 101 outputs an idiom first, the user performs corresponding voice response, the vehicle-mounted device 101 recognizes the user voice and matches the user voice with the idiom library, or the vehicle-mounted device 101 sends the recognized user voice to the server device 102, the server device 102 matches the user voice with the idiom library, whether the user response is correct or not is judged, and then the next round of interaction is performed according to the judgment result.
For example, the vehicle-mounted device 101 outputs idioms "plain sailing", the user makes a corresponding connection, for example, the user speaks "forward seal", after the vehicle-mounted device 102 recognizes the user voice, the user voice "forward seal" is sent to the server device 102, and the server device 102 matches the user voice with the idioms in the idiom library to determine whether the idioms are idioms, and further determines whether the end-to-end connection is satisfied. However, when the user answers the dragon, the user may speak some ineffective impurity voices due to the conditions of spoken language habit, word-of-word katon and the like, for example, when the user answers the dragon, the user speaks two words and pauses for thinking, after recognizing the user voice, the vehicle-mounted device 101 sends the user voice to the server device 102, and the server device 102 matches the user voice with the idioms in the idiom library to determine whether the idioms are idioms.
However, in the above case, the voice replied by the user is not actually required to be matched with the idiom library to determine that the voice replied by the user is not the idiom correctly connected, so that in this case, it is unnecessary to match the voice of the user with the idiom in the idiom library, and because the amount of data in the idiom library is large, the matching process is time-consuming, so that the response efficiency of voice interaction is low, and the user experience is poor.
The method can be applied to the field of Internet of vehicles in the field of artificial intelligence, and the method performs preliminary screening and filtering on the voice input by the user, performs subsequent matching processing on the filtered non-impurity voice, and does not need subsequent processing on the impurity voice, so that the processing efficiency is improved, and the voice interaction experience is better.
The voice interaction method provided by the application will be described in detail through specific embodiments. It is to be understood that the following embodiments may be combined with each other and that some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a flow chart of a voice interaction method according to an embodiment of the present application. The execution main body of the method is vehicle-mounted equipment. As shown in fig. 2, the method includes:
s201, outputting first prompt voice for prompting to input specific vocabulary.
The user can wake up through voice or touch selection on a screen of the vehicle-mounted device to start a voice interaction entertainment function of the vehicle-mounted device, and then the vehicle-mounted device outputs first prompt voice for prompting to input specific words. The first alert voices may also be different depending on the voice interactive entertainment function. For example, the first prompting voice may be a idiom randomly output by the vehicle-mounted device, and is used for prompting the user to make a dragon according to the idiom, for example, the vehicle-mounted device outputs "spring bloom"; alternatively, the first prompt voice may be a prompt message prompting the user to speak a idiom of a certain type, for example, the in-vehicle apparatus outputs "please speak idiom describing mood".
S202, in response to receiving the voice information, judging whether the number of words included in the voice information is larger than or equal to a preset value.
The user speaks corresponding voice information according to the heard first prompt voice to answer, the vehicle-mounted equipment receives the voice information input by the user and then recognizes the voice information, and specifically, a voice recognition engine in the vehicle-mounted equipment can convert the voice information into text information.
After the vehicle-mounted equipment recognizes the voice information, whether the number of words included in the voice information is larger than or equal to a preset value is continuously judged. For example, since the number of words of the idiom is generally 4 words or more, the preset value may be set to 4, that is, whether the number of words included in the voice information is greater than or equal to 4 is determined, so that a part of the impurity voice is filtered by the number of words.
S203, if the number of words included in the voice information is greater than or equal to a preset value, matching the voice information with a preset information base.
When the number of words included in the voice information is greater than or equal to a preset value, the voice information is determined to be a reply of the user according to the first prompt voice, so that the voice information is matched with a preset information base, the preset information base can be a idiom base, whether the reply of the user is correct or not is determined according to a matching result, and a second prompt voice is output. For example, the vehicle-mounted device outputs "spring bloom", and if the voice information input by the user is "mountain-blooming nose ancestor", the voice information is continuously matched with the preset information base because the voice information comprises 4 words. Here, the vehicle-mounted device may send the recognized voice information to the server device, so that the server device matches the voice information with the preset information base, or the vehicle-mounted device may match the voice information with the preset information base by itself, which is not limited in this embodiment.
S204, outputting a second prompt voice according to the matched result.
If the voice information input by the user is successfully matched with the preset information base, the second prompt voice can be a prompt voice interacted again, for example, the idiom is correct, and the vehicle-mounted equipment outputs the idiom of the idiom receiving user voice; if the matching of the voice information input by the user and the preset information base fails, the second prompting voice can prompt the user to input a new idiom again or perform a new round of interaction, for example, the idiom is failed to connect, and the second prompting voice can prompt the user to input the idiom again or output a new idiom again to perform a new interaction.
According to the voice interaction method provided by the embodiment, the word number screening is carried out on the voice input by the user, the impurity voice with fewer words is initially filtered, and only the effective voice information with more words is subjected to subsequent matching processing, so that the interaction response efficiency is prevented from being influenced by the processing of the impurity voice, and the voice interaction experience is better.
On the basis of the above embodiment, if the number of words included in the voice information input by the user is smaller than the preset value, a third prompting voice is output, and the third prompting voice is used for prompting the user to reenter the specific vocabulary. For example, the in-vehicle device outputs "spring bloom", the voice information input by the user is "what is on", and since the number of words of the voice information is 3 words, it is not necessary to match the voice information with the preset information base, but the third prompting voice is directly output, for example, the third prompting voice may be "please speak the correct idiom again". If the matching process is processed by the server device, when the number of words included in the voice information input by the user is smaller than a preset value, the vehicle does not need to send the voice information input by the user to the server device, so that the flow consumption of the vehicle-mounted device is reduced.
In different voice interaction scenarios, the matching of the voice information with the preset information base in S204 in the above embodiment may be implemented in different manners, which is further described below.
Mode one
Matching the voice information with the first prompt voice; if the first word in the voice information is matched with the last word in the first prompt voice, the voice information is matched with a preset information base, and a second prompt voice is output according to the matching result.
In this implementation manner, taking the voice interaction function as a idiom receiving unit as an example, the first prompt voice is an idiom output by the vehicle-mounted device, after judging that the number of words included in the voice information input by the user is greater than or equal to a preset value, matching the voice information with the first prompt voice, if the first word in the voice information is matched with the last word in the first prompt voice, indicating that the voice information input by the user meets end-to-end connection, thus, further determining whether the voice information input by the user is idiom, and matching the voice information with a preset information library, namely, the idiom library, and outputting the second prompt voice according to a matching result.
If the first word in the voice information is not matched with the last word in the first prompt voice, the voice input by the user is not satisfied with the end-to-end connection, so that whether the voice information input by the user is idiom is not needed to be further determined, namely, the voice information is not needed to be matched with a preset information base, namely, the idiom base.
Because the data volume in the preset information base is larger, the matching process of the voice information and the preset information base is relatively time-consuming, so that the method of the embodiment can reduce the matching of the voice information and the preset information base and improve the response efficiency.
Mode two
Determining whether a plurality of words included in the voice information meet a preset format; if the plurality of words included in the voice information meet the preset format, the voice information is matched with a preset information base, and a second prompt voice is output according to the matching result.
In the implementation manner, taking the voice interaction function as an example of speaking the idioms meeting the requirements according to the prompt of the vehicle-mounted equipment, the first prompt voice is used for prompting the user to speak the idioms meeting the preset format. Illustratively, the first prompt voice prompts the user to speak idioms in AABB format. After the user inputs the voice information, after judging that the number of words included in the voice information is greater than or equal to a preset value, determining whether a plurality of words included in the voice information meet an AABB format, if the plurality of words included in the voice information meet the AABB format, further determining whether the voice information input by the user is idioms, and matching the voice information with a preset information base, namely a idiom base, and outputting a second prompt voice according to a matching result.
If the plurality of words in the voice information do not meet the preset format, whether the voice information input by the user is idiom or not is not needed to be further determined, namely, the voice information is not needed to be matched with a preset information base.
Because the data volume in the preset information base is large, the matching process of the voice information and the preset information base is relatively time-consuming, and therefore the method of the embodiment reduces the matching of the voice information and the preset information base through format matching and improves response efficiency.
Mode three
Matching the voice information with target labels in a preset information base; the target tag is a first alert voice indicated tag.
In this way, taking the voice interaction function as an example of the vehicle-mounted device to prompt the user to speak the idioms with the target tags, the first prompt voice is used to prompt the user to speak the idioms with the target tags. For example, the first alert voice is "please speak idioms describing moods". After the user inputs the voice information, after judging that the word number included in the voice information is larger than or equal to a preset value, determining that information of a target tag for describing moods in a preset information base is included, matching the voice information with the information of the target tag, and outputting second prompt voice according to a matching result.
For example, if 100 idioms with a target tag describing moods are in the idiom library, after judging that the number of words included in the voice information is greater than or equal to a preset value, matching the voice information with the 100 idioms, and determining whether the answer of the user is correct. By matching the voice information with the target label in the preset information base, the matching of the voice information with the whole preset information base is reduced, and the response efficiency is improved.
On the basis of any of the above matching modes, when matching the voice information with a preset information base, it can be further determined whether the voice information input by the user is historical voice information, wherein the historical voice information is information output by the vehicle-mounted device or input by the user before receiving the voice information; and if the voice information is not the historical voice information, matching the voice information with a preset information base.
For example, when the idiom is picked up, the user is not allowed to speak the idiom which has been spoken before, after the vehicle-mounted device outputs "give birth to pick up the meaning", the user picks up the meaning "thin cloud day", because the user picks up the meaning correctly, the vehicle-mounted device picks up the meaning "heaven and earth" again, if the user speaks the meaning "thin cloud day" again, because the idiom is historical voice information, the vehicle-mounted device prompts the user to speak a new idiom again. If the user receives the dragon "no review" the voice information is not the historical voice information, so the voice information is continuously matched with the preset information base to determine whether the answer of the user is correct.
According to the above various matching modes and the matching of the historical voice information in the embodiment, in the voice interaction method of the embodiment of the application, when the user voice is verified, other limiting conditions of voice interaction are firstly matched, finally, matching of idioms is carried out, if other limiting conditions are not met, matching of the idioms is not needed, and therefore response efficiency is improved, and user experience is improved.
In addition, in the preset time after the vehicle-mounted device outputs the first prompt voice, if voice information input by the user is not received, the vehicle-mounted device outputs fourth prompt voice which is used for prompting the user to finish voice interaction, and therefore the vehicle-mounted device is prevented from being in a monitoring state for a long time to wait for the user.
