The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

An embodiment of the present application discloses a voiceprint lock control method, as shown in FIG. 1 , the method includes: step 110 to step 140 .

Step 110, output the perception information of the voiceprint matching object stored in the voiceprint lock to the user.

The voiceprint lock control method described in the embodiment of the present application is applied to the voiceprint lock shown in FIG. A voice collection device 220 , a memory 230 , a lock actuator 240 and a sensory information output device 250 are connected in communication.

In some embodiments of the present application, the main control device 210 may be a processor with storage space. Referring to FIG. 3 , the memory 230 is built in the main control device 210 .

In the following, the functions of each component of the voiceprint lock will be described in conjunction with a specific implementation of the voiceprint lock control method.

The voiceprint matching objects described in the embodiments of the present application may be characters, words or sentences.

In some embodiments of the present application, a dictionary library is pre-stored in the voiceprint lock, and the dictionary library is stored in the memory 230. The dictionary library may include one of characters, words, sentences, and music clips. or multiple forms of voiceprint matching objects. The voiceprint matching objects (for example, characters, words, sentences, music fragments) stored in the dictionary database can be used to output to the user as voiceprint matching objects that need to register voiceprint information during the voiceprint registration stage, or can be used to In the voiceprint authentication stage, it is output to the user as a voiceprint matching object that prompts the user to perform voiceprint authentication.

When starting to use the voiceprint lock, you need to register the voiceprint first. As shown in FIG. 4 , before outputting the perception information of the voiceprint matching object stored in the voiceprint lock to the user, it further includes: Step 100 .

Step 100, register voiceprint information.

One or more pieces of registration voiceprint information generated when the user performs voiceprint registration will be stored in the registration voiceprint information database, and the registration voiceprint information database is stored in the voiceprint lock, for example, the registration voiceprint information database stores in the memory 230 . For example, when the voiceprint lock starts to be used, the main control device 210 randomly selects a voiceprint matching object from the dictionary library, and outputs the perception information through the perception information output device 250. The output of the perception information includes at least three ways, including The output device 250 displays the text content of the selected voiceprint matching object, or plays the voice of the selected voiceprint matching object, or displays the text content of the selected voiceprint matching object and plays the corresponding voice, and prompts the user for the selected voiceprint matching object. Then, the main control device 210 controls the voice collection device 220 to collect the user's feedback voice for the perceptual information, and extracts the voiceprint features in the feedback voice, as the selected voice print Then, correspondingly store the selected voiceprint matching object and the extracted registered voiceprint information in the registered voiceprint information database.

In some embodiments of the present application, each piece of registered voiceprint information stored in the registered voiceprint information database corresponds to a different voiceprint matching object, and the voiceprint matching object can be a single character, a single word, a complete sentence or music fragment. For example, in some embodiments of the present application, each piece of registered voiceprint information stored in the registered voiceprint information database corresponds to a different character. For another example, in some embodiments of the present application, each piece of registered voiceprint information stored in the registered voiceprint information database corresponds to a different word, or corresponds to a different sentence, or corresponds to a piece of music (pure melody music or music with music with lyrics). For another example, in some embodiments of the present application, some of the registered voiceprint information stored in the registered voiceprint information database correspond to characters, some correspond to words, and some correspond to music clips. Among them, the voiceprint information corresponding to different registered voiceprint information Match objects vary.

Each piece of registered voiceprint information in the registered voiceprint information database stored by the voiceprint lock is stored in association with its corresponding voiceprint matching object. The voiceprint matching object stored in the registered voiceprint information database is used to output to the user as a voiceprint matching object that prompts the user to perform voiceprint authentication during the voiceprint authentication stage.

The voiceprint matching object described in the embodiment of the present application can be stored in the dictionary database, or can be stored in the registered voiceprint information database, or can be the voiceprint matching object stored in the dictionary database and the registered voiceprint information The voiceprint matching object formed by combining the voiceprint matching objects in the library. For example, the voiceprint matching object can be a word stored in a dictionary, or a character or a word stored in a registered voiceprint information database, or a word and a word stored in a registered voiceprint information database. Words or sentences formed by combining the words in .

During the use of the voiceprint lock, the voiceprint lock first outputs to the user the perception information of the voiceprint matching object that requires voiceprint authentication, and then further collects the voiceprint information to be recognized input by the user for the voiceprint matching object. Wherein, the perceptual information output method of the voiceprint matching object includes displaying text, reading voice, and/or playing music clips. In some embodiments of the present application, the perceptual information output device 250 is used to output the perceptual information of the voiceprint matching object, and the voice collection device 220 is used to collect the feedback voice input by the user for the voiceprint matching object, so as to facilitate The voiceprint information to be recognized is extracted from the collected feedback voice.

The main control device 210 is used to control the perception information output device 250 to output the perception information of the voiceprint matching object stored in the voiceprint lock to the user.

In some embodiments of the present application, outputting the perception information of the voiceprint matching object stored in the voiceprint lock to the user includes: showing the user the text of the voiceprint matching object stored in the voiceprint lock, playing the text of the voiceprint matching object stored in the voiceprint lock to the user. The reading voice of the stored voiceprint matching object, and/or, playing the music clip of the voiceprint matching object stored in the voiceprint lock to the user. For example, the voiceprint lock reads any voiceprint matching object from the dictionary library, and displays the text of the voiceprint matching object to the user, and at the same time, plays the reading voice of the voiceprint matching object to prompt the user to input The voiceprint information to be identified corresponding to the voiceprint matching object. For another example, the voiceprint lock arbitrarily selects a voiceprint matching object from the registered voiceprint information database, and displays the text of the voiceprint matching object, so as to prompt the user to input the waiting time corresponding to the voiceprint matching object by reading the text content aloud. Identify voiceprint information.

Wherein, the reading voice of the voiceprint matching object may be the reading voice of the voiceprint matching object pre-stored in the dictionary database, or it may be the text-to-speech module built in the voiceprint lock according to the voiceprint matching object's reading voice. The reading voice obtained by text conversion. In the embodiment of the present application, there is no limitation on the manner of acquiring the spoken voice of the voiceprint matching object.

Step 120, in response to the voiceprint lock collecting the feedback voice for the perceptual information, determine voiceprint information to be recognized in the feedback voice.

After outputting the perception information of the currently to-be-recognized voiceprint matching object, the main control device 210 is further configured to determine the voice to be recognized in the feedback voice in response to the feedback voice for the perception information collected by the voiceprint lock. pattern information.

For example, after the voiceprint locker presents the voiceprint matching object "Sesame" to be recognized and plays its reading voice, the main control device 210 controls the voice collection device 220 to collect the user's feedback voice for the voiceprint matching object "Zesame". When the user reads "zhima" aloud, the voice collection device 220 will collect the audio data of "zhima" (that is, the feedback voice) and send it to the main control device 210 . Afterwards, after the main control device 210 receives the audio data of "zhima", it determines the voiceprint information to be recognized in the feedback voice through a voiceprint extraction algorithm.

In the embodiment of this application, the main control device 210 can also use other technical means in the prior art to determine the voiceprint information to be recognized in the feedback voice. The specific implementation manner of recognizing the voiceprint information is not limited.

Step 130, perform voiceprint matching on the voiceprint information to be recognized and the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and determine the matching result obtained by the voiceprint matching.

After determining the voiceprint information to be recognized input by the user for the current voiceprint matching object, the main control device 210 is further configured to combine the voiceprint information to be recognized with the registered voiceprint information stored in the voiceprint lock Perform voiceprint matching on the registered voiceprint information in the library, and determine the matching result obtained from the voiceprint matching.

In some embodiments of the present application, multiple voiceprint matching means can be used to perform voiceprint matching between the voiceprint information to be recognized and the registered voiceprint information. Examples are given below.

The first solution is to perform overall matching on the voiceprint information to be recognized.

When performing overall matching on the voiceprint information to be recognized, according to whether the current voiceprint matching object for which the feedback voice is targeted has already registered the corresponding voiceprint information, different strategies are used to select the registered voiceprint information stored in the registered voiceprint information database for use with The to-be-recognized voiceprint information is matched. In the following, the overall matching schemes in the two cases where the corresponding voiceprint information has been registered for the current voiceprint matching object of the feedback voice and the corresponding voiceprint information has not been registered are illustrated respectively.

In some embodiments of the present application, performing voiceprint matching on the voiceprint information to be identified and registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and determining that performing voiceprint matching The obtained matching result includes: in response to the registered voiceprint information corresponding to the voiceprint matching object in the registered voiceprint information database stored in the voiceprint lock, combining the voiceprint information to be identified with the registered voiceprint information performing voiceprint matching on registered voiceprint information corresponding to the voiceprint matching object in the voiceprint information database, and determining a matching result obtained by performing voiceprint matching.

Taking the registered voiceprint information of the voiceprint matching object "Sesame" in the voiceprint lock as an example, an example of a round of overall matching scheme is illustrated. After the voiceprint lock outputs the text of the voiceprint matching object "Sesame", the main control device 210 controls the voice collection device 220 to collect the user's feedback voice for the voiceprint matching object "Sesame", and extract the voiceprint in the feedback voice Information, as the voiceprint information to be recognized. Next, the main control device 210 judges whether the voiceprint matching object "Sesame" has registered voiceprint information. In some embodiments of the present application, it can be determined by comparing the voiceprint matching object "Zesame" with the voiceprint matching object corresponding to the registered voiceprint information stored in the registered voiceprint information database of the voiceprint lock. Whether the voiceprint matching object "Zhima" has registered voiceprint information. If the comparison is successful, it can be considered that the voiceprint matching object "Sesame" has registered voiceprint information, otherwise, it can be considered that the voiceprint matching object "Zesame" has not registered voiceprint information. In other embodiments of the present application, during the registration phase, the voiceprint lock can mark the voiceprint matching object that has registered registered voiceprint information. Correspondingly, during the voiceprint matching phase, the Whether the voiceprint matching object has registered voiceprint information.

After it is determined that the voiceprint matching object "Zesame" has registered voiceprint information, further obtain the registered voiceprint information correspondingly stored in the registered voiceprint information database of the voiceprint matching object "Zesame", and store the acquired voiceprint matching object " Sesame” performs voiceprint matching between the registered voiceprint information stored in the registered voiceprint information database and the currently collected voiceprint information to be recognized, and determines the voiceprint matching result.

In some embodiments of the present application, performing voiceprint matching on the voiceprint information to be identified and registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and determining that performing voiceprint matching The obtained matching result includes: in response to the fact that there is no registered voiceprint information corresponding to the voiceprint matching object in the registered voiceprint information database stored in the voiceprint lock, combining the voiceprint information to be identified with the voiceprint information Perform voiceprint matching on any one or more pieces of registered voiceprint information in the registered voiceprint information database stored in the fingerprint lock, and determine the matching result obtained by performing the voiceprint matching.

Taking the registered voiceprint information of the unregistered voiceprint matching object "Apple" in the voiceprint lock as an example, an example of a round of overall matching scheme is illustrated. After the voiceprint lock outputs the text of the voiceprint matching object "Apple", the main control device 210 controls the voice collection device 220 to collect the user's feedback voice for the voiceprint matching object "Apple", and extract the voiceprint in the feedback voice Information, as the voiceprint information to be recognized. Next, the main control device 210 judges whether the voiceprint matching object "Apple" has registered voiceprint information. In some embodiments of the present application, it may be determined by comparing the voiceprint matching object "apple" with the voiceprint matching object corresponding to the registered voiceprint information stored in the registered voiceprint information database of the voiceprint lock. Whether the voiceprint matching object "Apple" has registered voiceprint information. If the comparison is successful, it can be considered that the voiceprint matching object "Apple" has registered voiceprint information; otherwise, it can be considered that the voiceprint matching object "Apple" has not registered voiceprint information. In other embodiments of the present application, during the registration phase, the voiceprint lock can mark the voiceprint matching object that has registered registered voiceprint information. Correspondingly, during the voiceprint matching phase, the Whether the voiceprint matching object has registered voiceprint information.

After determining the unregistered voiceprint information of the voiceprint matching object "Apple", further obtain any piece of registered voiceprint information stored in the registered voiceprint information database, and combine the acquired registered voiceprint information with the currently collected voiceprint information to be recognized Perform voiceprint matching and determine the voiceprint matching result.

In some embodiments of the present application, the voiceprint matching result may be determined by calculating the similarity between the registered voiceprint information and the voiceprint information to be recognized. For example, if the similarity between the registered voiceprint information and the voiceprint information to be identified is greater than the preset similarity threshold, it can be considered that the registered voiceprint information and the voiceprint information to be identified are successfully matched; otherwise, the registered voiceprint information and the voiceprint information to be identified are considered to be Pattern information matching failed.

In some embodiments of the present application, different similarity thresholds can be set for different situations of whether the voiceprint matching object has registered voiceprint information, so as to reduce the influence of the text content corresponding to the voiceprint information on the voiceprint information similarity calculation. For example, when the voiceprint matching object has registered voiceprint information, and the voiceprint information to be recognized is compared with the registered voiceprint information corresponding to the voiceprint matching object, the preset similarity threshold can be set to the first Threshold; when the voiceprint matching object does not have registered voiceprint information, the voiceprint information to be identified is compared with any piece of registered voiceprint information, and the preset similarity threshold can be set to the second threshold, where the first A threshold is greater than the second threshold.

In some embodiments of the present application, the registered voiceprint information in the registered voiceprint information database includes the registered voiceprint information stored in the original registration stage, and may also include the registered voiceprint information stored in the voiceprint authentication stage when the registered voiceprint information database is updated and maintained. Register voiceprint information.

The second solution is to perform segmentation matching on the voiceprint information to be recognized.

In some embodiments of the present application, in the voiceprint authentication stage, the voiceprint matching object output by the voiceprint lock can also be a voiceprint matching object composed of multiple voiceprint matching objects with unregistered voiceprint information in the dictionary database (For example, for the voiceprint matching objects "Qing" and "Lu" that have not registered voiceprint information in the dictionary database, they can be combined into the voiceprint matching object "Qinglu"), or unregistered voiceprint information in the dictionary database A voiceprint matching object formed by combining one or more voiceprint matching objects in the registered voiceprint information database with one or more voiceprint matching objects stored in the registered voiceprint information database (for example, for a voiceprint that has no registered voiceprint information in the dictionary database The matching object "Qing" and the voiceprint matching object "Sesame" stored in the registered voiceprint information database can be combined into the voiceprint matching object "Qingzhima"), or one or more voiceprint matching objects stored in the registered voiceprint information database. Voiceprint matching objects formed by combining voiceprint matching objects (for example, for the voiceprint matching objects "Sesame" and "Orange" stored in the registered voiceprint information database, they can be combined into the voiceprint matching object "Sesame Orange").

For scenarios where voiceprint matching objects can be combined to generate a composite voiceprint matching object, in some embodiments of the present application, segmentation matching can be performed on the voiceprint information to be recognized. Combine at least two voiceprint matching objects to generate a composite voiceprint matching object, which is used for voiceprint authentication in the voiceprint authentication stage, and randomly combine to generate voiceprint matching objects, which can improve the security of the voiceprint lock. Further, select the voiceprint matching object of unregistered voiceprint information from the dictionary library and the voiceprint matching object selected from the registered voiceprint information database to generate a composite voiceprint matching object, and can also realize the silent update of the registered voiceprint information database , thereby further enhancing the security of the voiceprint lock.

The following is an example of voiceprint authentication by selecting a voiceprint matching object with unregistered voiceprint information from the dictionary database and a registered voiceprint matching object from the registered voiceprint information database to generate a composite voiceprint matching object. A specific technical solution for segmented recognition of voiceprint information to be recognized. In the embodiments of this application, in order to make the description clearer, the voiceprint matching object of the registered voiceprint information in the registered voiceprint information database is called "the first voiceprint matching object", and the unregistered voiceprint information in the dictionary database is referred to as "first voiceprint matching object". The voiceprint matching object is called the "second voiceprint matching object". Wherein, for example, the first voiceprint matching object and the second voiceprint matching object are basic voiceprint matching units, for example, the first voiceprint matching object and the second voiceprint matching object are a single character or single words.

In some embodiments of the present application, the voiceprint matching object is based on the first voiceprint matching object of the registered voiceprint information stored in the registered voiceprint information database, and the dictionary library stored in the voiceprint lock The second voiceprint matching object in the combination is generated, and the voiceprint matching is performed on the voiceprint information to be recognized and the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and the determined The matching result obtained by voiceprint matching includes: determining the pieces of voiceprint information to be recognized corresponding to each of the first voiceprint matching objects and each of the second voiceprint matching objects in the voiceprint information to be recognized; performing voiceprint matching on the voiceprint information segments to be identified corresponding to each of the first voiceprint matching objects and the corresponding registered voiceprint information; and matching the voiceprint information segments to be identified corresponding to each of the second voiceprint matching objects Perform voiceprint matching on the registered voiceprint information selected in the registered voiceprint information database, and determine the voiceprint information to be identified and the voiceprint matching object (i.e. the first voiceprint matching object, the second voiceprint matching object) ) voiceprint matching results. In some embodiments of the present application, the selected registered voiceprint information includes: a randomly selected piece of registered voiceprint information corresponding to the first voiceprint matching object whose character distance is closest to the second voiceprint matching object registered voiceprint information.

In some embodiments of the present application, when generating a composite voiceprint matching object to be output to the user, the main control device 210 may simultaneously record the first voiceprint matching object and the second voiceprint matching object that make up the composite voiceprint matching object. Afterwards, when extracting the voiceprint information to be recognized, speech recognition can be performed on the feedback voice used to extract the voiceprint information to be recognized at the same time, to obtain a character sequence, and further match the object and the second voiceprint with the first voiceprint according to the character sequence The character matching result of the matching object is divided into the voiceprint information to be recognized, and the voiceprint information segments to be recognized corresponding to each first voiceprint matching object and each second voiceprint matching object included in the composite voiceprint matching object are determined . As an example, the voiceprint matching object is composed of the second voiceprint matching object "Qing" that has no voiceprint information registered in the dictionary database and the first voiceprint matching object "Zesame" stored in the registered voiceprint information database. The voiceprint information will be divided into a piece of voiceprint information to be recognized corresponding to the second voiceprint matching object "Qing" (hereinafter denoted as F1), and a piece of waiting-to-be-recognized voiceprint information corresponding to the first voiceprint matching object "Sesame". Identify the piece of voiceprint information (hereinafter denoted as F2).

Next, determine the registered voiceprint information for voiceprint matching with each piece of voiceprint information to be recognized after segmentation.

In some embodiments of the present application, for each piece of voiceprint information to be recognized (such as the piece of voiceprint information to be recognized F2) corresponding to the first voiceprint matching object (such as the aforementioned "Sesame"), the voiceprint to be recognized is The voiceprint information segment (such as F2) is matched with the registered voiceprint information correspondingly stored in the registered voiceprint information database corresponding to the first voiceprint matching object (such as "Sesame"), and the voiceprint information segment corresponding to the voiceprint information segment to be identified is determined. Voiceprint matching result.

In some embodiments of the present application, for each voiceprint information segment to be recognized (such as the voiceprint information segment F1 to be recognized) corresponding to the second voiceprint matching object (such as the aforementioned "Qing"), the to-be-identified voiceprint information segment can be The voiceprint information segment (such as F1) performs voiceprint matching with any piece of registered voiceprint information stored in the registered voiceprint information database, and determines the voiceprint matching result corresponding to the voiceprint information segment to be recognized. For example, voiceprint matching can be performed on the piece of voiceprint information to be recognized (such as F1) and the registered voiceprint information correspondingly stored in the registered voiceprint information database of the first voiceprint matching object (such as "Sesame"), and determine the voiceprint information to be identified. Identify the voiceprint matching result corresponding to the voiceprint information segment.

Since the pronunciation of the characters in the voice is continuous when the user inputs a complete voice, therefore, for the piece of voiceprint information to be recognized corresponding to the second voiceprint matching object, the character with the closest distance to the second voiceprint matching object is used. The registration voiceprint information corresponding to the first voiceprint matching object performs voiceprint matching, which can improve the matching accuracy of voiceprint authentication.

In some embodiments of the present application, the information of the first voiceprint matching object and the information of the second voiceprint matching object that make up the compound voiceprint matching object can also be output separately, so that the user can input the information for the first voiceprint matching object respectively. The feedback voice of the information, and the feedback voice for the second voiceprint matching object, so that the main control device 210 can directly obtain the voiceprint information segment corresponding to the first voiceprint matching object, and the second voiceprint matching object The corresponding piece of voiceprint information to be recognized.

When a complex voiceprint matching object is generated by selecting a combination of voiceprint matching objects with unregistered voiceprint information from the dictionary library for voiceprint authentication, or a complex voiceprint matching object is generated by selecting a combination of voiceprint matching objects from the registered voiceprint information database When performing voiceprint authentication, only segments of the voiceprint information to be identified corresponding to each first voiceprint matching object are segmented out of the voiceprint information to be identified, or only pieces of voiceprint information corresponding to each second voiceprint information are segmented out. The piece of voiceprint information to be recognized corresponding to the fingerprint matching object. For the specific implementation manner of performing voiceprint matching on each piece of voiceprint information to be recognized, refer to the foregoing description, which will not be repeated here.

In some embodiments of the present application, if the registered voiceprint information corresponding to the first voiceprint matching object is matched with the corresponding piece of voiceprint information to be identified and the matching degree determined after voiceprint matching is greater than the first matching degree threshold, the first voiceprint is considered to be The voiceprint matching of the segment of voiceprint information to be identified corresponding to the matching object is successful; the matching degree determined after voiceprint matching between the registration voiceprint information corresponding to the second voiceprint matching object and the corresponding segment of voiceprint information to be identified is greater than that of the second matching degree threshold, it is considered that the voiceprint of the to-be-recognized voiceprint information segment corresponding to the second voiceprint matching object is successfully matched, wherein the first matching degree threshold is greater than the second matching degree threshold.

In some embodiments of the present application, the voiceprint to be recognized is considered to be recognized only when the pieces of voiceprint information to be recognized corresponding to each of the first voiceprint matching object and the second voiceprint matching object that are combined to generate a composite voiceprint matching object are successfully matched. Information matching is successful. If the segment of voiceprint information to be recognized corresponding to a certain first voiceprint matching object or a certain second voiceprint matching object combined to generate a composite voiceprint matching object fails to match, it is considered that the matching of the entire voiceprint information to be recognized is unsuccessful.

In some other embodiments of the present application, when the pieces of voiceprint information to be identified corresponding to each first voiceprint matching object that are combined to generate a composite voiceprint matching object are successfully matched, it is considered that the voiceprint information to be identified is matched successfully .

Step 140, in response to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, perform the processing of the registered voiceprint information based on the voiceprint information to be recognized. An update operation of the library, and an unlock control operation of the voiceprint lock.

After performing voiceprint matching on the user's voiceprint information to be recognized through the aforementioned steps, if the matching is successful, the main control device 210 will control the lock actuator 240 to open the door lock, and if the matching fails, the door lock will not be opened.

At the same time, if the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, the main control device 210 will also execute the registration of the registered voiceprint information database based on the voiceprint information to be recognized. update operation.

In some embodiments of the present application, in response to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, performing a process based on the voiceprint information to be recognized The update operation of the registered voiceprint information database includes: responding to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, updating the voiceprint information to be recognized The voiceprint information is stored in the registered voiceprint information database as the registered voiceprint information corresponding to the voiceprint matching object, or the registered voiceprint information in the registered voiceprint information database is updated and maintained. For example, after the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, the main control device 210 first determines whether there is corresponding registered voiceprint information in the voiceprint matching object output to the user. , if the voiceprint matching object does not store corresponding registered voiceprint information in the registered voiceprint information database, then update the registered voiceprint information database with the current voiceprint information to be identified; if the voiceprint matching object is registered If the corresponding registered voiceprint information is stored in the voiceprint information database, the registered voiceprint information database is not updated with the current voiceprint information to be recognized, that is, there is no need to operate the registered voiceprint information database.

In some embodiments of the present application, when updating the registered voiceprint information database with the current voiceprint information to be identified, if the number of registered voiceprint information stored in the registered voiceprint information database stored in the voiceprint lock is greater than or is equal to the preset number threshold, the registered voiceprint information database is updated and maintained through the current voiceprint information to be recognized. For example, delete a set of correspondence data between voiceprint matching objects and registered voiceprint information according to preset rules, and then use the voiceprint information to be recognized that is currently successfully matched with the voiceprint matching object as the registered voiceprint information corresponding to the voiceprint matching object. The voiceprint information is stored in the registered voiceprint information database corresponding to the voiceprint matching object.

In other embodiments of the present application, when updating the registered voiceprint information database with the current voiceprint information to be identified, if the number of registered voiceprint information stored in the registered voiceprint information database stored in the voiceprint lock is less than If the number threshold is preset, the voiceprint information to be recognized that is currently successfully matched with the voiceprint matching object is directly used as the registered voiceprint information corresponding to the voiceprint matching object, and stored in the registration voiceprint corresponding to the voiceprint matching object in the information base.

Wherein, the preset number threshold is determined according to the storage capacity of the registered voiceprint information database in the voiceprint lock.

In some embodiments of the present application, in response to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, performing a process based on the voiceprint information to be recognized The update operation of the registered voiceprint information database includes: responding to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, updating each of the second voiceprint information The piece of voiceprint information to be matched corresponding to the fingerprint matching object is stored in the registered voiceprint information database as the registered voiceprint information corresponding to each of the second voiceprint matching objects or for the registered voiceprint information database. Register voiceprint information for update and maintenance.

For example, when the voiceprint matching object is a composite voiceprint matching object including the first voiceprint matching object and/or the second voiceprint matching object, update Register voiceprint database. Still taking the aforementioned compound voiceprint matching object "Qing Zhima" as an example, when the voiceprint information segment F2 to be recognized corresponding to the first voiceprint matching object "Zhima" and the voiceprint to be recognized corresponding to the second voiceprint matching object "Qing" After the information fragments F1 are all successfully matched, or when the voiceprint information fragment F2 corresponding to the first voiceprint matching object "Sesame" is successfully matched, it is determined that the voiceprint information matching for the voiceprint matching object "Qing Zhima" is matched. If it succeeds, at this time, the main control device 210 uses the voiceprint information segment F1 corresponding to the second voiceprint matching object "Qing" to be recognized as the registered voiceprint information of the second voiceprint matching object "Qing", and sends the second voiceprint matching object "Qing" The pattern matching object "Qing" and the voiceprint information fragment F1 to be identified are directly stored in the registered voiceprint information database in the voiceprint lock, or a group of voiceprint matching objects and registered voiceprint information are deleted according to preset rules After that, the to-be-recognized voiceprint information segment F1 is used as the registered voiceprint information corresponding to the second voiceprint matching object, and stored corresponding to the second voiceprint matching object in the registered voiceprint information database.

In some embodiments of the present application, in order to further improve the security of voiceprint authentication, the voiceprint matching object can be split into independent voiceprint matching units in the registration stage, so as to facilitate the flexible combination and generation of multiple composites in the voiceprint authentication stage. The voiceprint matching object. Wherein, the registration stage further includes: outputting to the user the perception information of the voiceprint matching object to be registered stored in the dictionary database of the voiceprint lock; collecting the registration voice of the user for the perception information of the voiceprint matching object to be registered, And determine the registration voiceprint information corresponding to the registered voice; split the voiceprint matching object to be registered, and determine the independent voiceprint matching objects that form the voiceprint matching object to be registered; determine the voiceprint matching objects respectively Registering the registered voiceprint information segments corresponding to each of the independent voiceprint matching objects in the registered voiceprint information, and then storing each of the registered voiceprint information segments as the registered voiceprint information of the corresponding independent voiceprint matching objects in In the registered voiceprint information database of the voiceprint lock.

The following takes the registered voiceprint information corresponding to the originally registered voiceprint matching object "Zhima" as an example to illustrate the voiceprint registration process.

First, the main control device 210 randomly selects the voiceprint matching object "Sesame" from the dictionary database as the voiceprint matching object to be registered, and displays the text content of the voiceprint matching object "Sesame" to be registered through the sensory information output device 250, and/ Or, play the reading voice of the voiceprint matching object "Zesame" to be registered, so as to output the perceptual information of the voiceprint matching object "Zesame" to be registered; after that, prompt the user for the voiceprint matching object "Zesame" to be registered Register the voiceprint information; then, the main control device 210 controls the voice collection device 220 to collect the user's feedback voice on the perceptual information as the registration voice. After collecting the registration voice of "Zesame" presented by the user for the voiceprint lock, extract the voiceprint features in the registration voice as the registration voiceprint information corresponding to the registration voice, that is, as the registration of the voiceprint matching object "Zesame". Voiceprint information.

In the embodiment of this application, different from the silent voiceprint registration process in the voiceprint authentication stage, the voiceprint registration process described here does not need to combine the collected voiceprint features with the registered voiceprint information stored in the registered voiceprint information database. Therefore, the voiceprint registration process that does not need to compare the collected voiceprint features with the registered voiceprint information stored in the registered voiceprint information database is called the original registration process.

Further, the main control device 210 splits the voiceprint matching object "Sesame" to be registered according to preset rules (such as splitting by single character), and determines the components that make up the voiceprint matching object "Sesame" to be registered. Two independent voiceprint matching objects "zhi" and "ma", after that, further split the registered voiceprint information corresponding to the registered voice, and determine that the registered voiceprint information matches the independent voiceprint obtained by splitting The registered voiceprint information segments corresponding to the objects "Zhi" and "Ma" respectively; then, the main control device 210 stores the split independent voiceprint matching object "Zhi" and the corresponding registered voiceprint information segments in the registered voiceprint In the information database of the registered voiceprint, the independent voiceprint matching object "Ma" and the corresponding registered voiceprint information fragment obtained by splitting are correspondingly stored in the registered voiceprint information database, and a total of two pieces of registered voiceprint data are generated.

In some embodiments of the present application, the independent voiceprint matching object may only include a single character, or may include both a single character and a word. For example, when performing voiceprint registration on the voiceprint matching object "I'm back" in the dictionary database, the registered voiceprint information extracted from the user's registered voice can be split into three parts: "I", "Come back" and "Are". The registered voiceprint information segments corresponding to each of the independent voiceprint matching objects are stored as registered voiceprint information of three independent voiceprint matching objects in the registered voiceprint information database.

The voiceprint lock control method disclosed in the embodiment of the present application outputs the perception information of the voiceprint matching object stored in the voiceprint lock to the user; in response to the feedback voice for the perception information collected by the voiceprint lock, the feedback is determined. The voiceprint information to be recognized in the voice; the voiceprint information to be recognized is matched with the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and the voiceprint matching is determined to obtain The matching result; in response to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, performing the registration of the registered voiceprint based on the voiceprint information to be recognized The updating operation of the information base and the execution of the unlocking control operation of the voiceprint lock effectively improve the security of the voiceprint lock.

The voiceprint lock control method disclosed in the embodiment of the present application enriches the registered voiceprint information database in the voiceprint lock by updating the registered voiceprint information base in the voiceprint lock based on the currently matched voiceprint information to be identified after the voiceprint is successfully matched. The registered voiceprint information, and the dynamic update of the registered voiceprint information in the registered voiceprint information database is realized, which effectively improves the security of the voiceprint lock. Further, by updating the registered voiceprint information database in the voiceprint lock only based on the voiceprint information to be recognized of the voiceprint matching object that has not registered voiceprint information, it can ensure that the registered voiceprint information in the registered voiceprint information database The diversity of fingerprint information further enhances the security of voiceprint locks.

Referring to FIG. 5 , a voiceprint lock control method disclosed in another embodiment of the present application is applied to the voiceprint lock shown in FIG. 2 and FIG. 3 , and the method further includes a voice recognition step. As shown in FIG. 5 , the method includes: Step 510 to Step 580 .

Step 510, output the perception information of the voiceprint matching object stored in the voiceprint lock to the user.

For a specific implementation manner of outputting the perception information of the voiceprint matching object stored in the voiceprint lock to the user, refer to the above-mentioned embodiments, and details will not be repeated in this embodiment.

Step 520: Responsive to the feedback voice for the perception information collected by the voiceprint lock, perform voice recognition on the feedback voice, and determine a voice recognition result corresponding to the feedback voice.

After the main control device 210 of the voiceprint lock receives the feedback voice for the perceptual information collected by the voice collection device 220, it first performs voice recognition on the feedback voice, and determines the voice recognition corresponding to the feedback voice. As a result, the content of the text spoken by the user is determined.

For a specific implementation manner of performing speech recognition on the feedback speech and determining a speech recognition result corresponding to the feedback speech, refer to speech recognition methods in the prior art, and this application does not limit the speech recognition method of the feedback speech.

Step 530, perform text matching on the speech recognition result corresponding to the feedback speech and the speech recognition result corresponding to the registered voiceprint information of the voiceprint matching object in the registered voiceprint information database stored in the voiceprint lock.

For example, in the voiceprint registration stage, the main control device 210 randomly selects the voiceprint matching object "Sesame" from the dictionary database as the voiceprint matching object to be registered, and displays the voiceprint matching object "Sesame" to be registered through the sensory information output device 250 The text content of the voiceprint matching object to be registered, and/or, playing the reading voice of the voiceprint matching object to be registered, so as to output the perceptual information of the voiceprint matching object to be registered; Register the voiceprint information; then, the main control device 210 controls the voice collection device 220 to collect the user's feedback voice on the perceptual information as the registration voice. After collecting the registration voice of "Zesame" displayed by the user for the voiceprint lock, extract the voiceprint features in the registration voice as the registration voiceprint information corresponding to the registration voice, that is, as the registration of the voiceprint matching object "Zesame" At the same time, the main control device 210 performs voice recognition on the registered voice, determines the voice recognition result corresponding to the registered voice—the text "Sesame", and matches the currently registered voiceprint with the object (i.e. the word "Sesame"), The speech recognition result corresponding to the registered voice (that is, the text "sesame") and the registered voiceprint information corresponding to the registered voice are associated and stored in the registered voiceprint information database.

In some embodiments of the present application, the voice recognition result corresponding to the registered voiceprint information of the voiceprint matching object is user-defined registration text for the voiceprint matching object. For example, in the voiceprint registration stage, when the voiceprint lock outputs the perception information of the voiceprint matching object whose voiceprint information is to be registered, the user can customize the voice recognition result corresponding to the voiceprint matching object to improve the security of the voiceprint lock sex. For example, when the perceptual information output device 250 displays the text content of the voiceprint matching object to be registered "Sesame", and/or plays the reading voice of the voiceprint matching object to be registered, so as to output the voiceprint matching object to be registered perception information; after that, the user is prompted to register voiceprint information for the voiceprint matching object "Zhima" to be registered, and the user can read "kaimen", which is the pronunciation of the text "open the door", as the registered voice. In this way, the voiceprint lock will store the voiceprint matching object (that is, the word "sesame"), the speech recognition result corresponding to the registered voice (that is, the text "open the door"), and the registered voiceprint information corresponding to the registered voice (that is, the user reads "kaimen The voiceprint features extracted from the voice of ") are associated and stored in the registered voiceprint information base.

In the voiceprint authentication stage, when the main control device 210 receives the feedback voice (such as the pronunciation of the text "open the door") collected by the voice collection device 220 for the perceptual information (such as the text content of the displayed voiceprint matching object "Sesame") ), performing speech recognition on the feedback speech, and determining the speech recognition result corresponding to the feedback speech (such as the recognized speech recognition result being the text “open the door”), after that, the master control device 210 converts the feedback speech corresponding to The speech recognition result is text-matched with the speech recognition result corresponding to the registered voiceprint information of the voiceprint matching object "Zesame" in the registered voiceprint information database stored in the voiceprint lock (such as the aforementioned text "open the door").

Step 540, determine whether the speech recognition result corresponding to the feedback speech matches the speech recognition result corresponding to the registered voiceprint information of the voiceprint matching object, if so, perform step 550, otherwise, jump to step 580.

In some embodiments of the present application, the determination is performed in response to the text matching result indicating that the speech recognition result corresponding to the feedback voice matches the speech recognition result corresponding to the registered voiceprint information of the voiceprint matching object. The step of feeding back the voiceprint information to be recognized in the voice; otherwise, ending the current voiceprint unlocking process. For example, if during the registration stage, the registration voice entered by the user for the voiceprint matching object "Zhima" is the pronunciation of the custom text "Open the door", in the voiceprint authentication stage, if the user still reads "Open the door" for the voiceprint matching object "Zesame". ", the speech recognition is successful. If the user reads "Sesame" for the voiceprint matching object "Sesame", it is considered that the speech recognition fails.

If the voice recognition is successful, continue to the subsequent voiceprint authentication steps, otherwise, end the current voiceprint authentication process.

Step 550, determine voiceprint information to be recognized in the feedback voice.

For a specific implementation manner of determining the to-be-recognized voiceprint information in the feedback voice, refer to the foregoing embodiments, and details are not repeated in this embodiment.

Step 560: Perform voiceprint matching on the voiceprint information to be recognized and the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and determine the matching result obtained by performing the voiceprint matching.

Step 630: Perform voiceprint matching on the voiceprint information to be recognized and the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and determine the matching result obtained by performing the voiceprint matching.

Perform voiceprint matching on the voiceprint information to be identified with the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, and determine the matching result obtained by performing voiceprint matching, refer to the above Embodiment, which will not be repeated in this embodiment.

Step 640: In response to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, output the perception information of unregistered voiceprint matching objects in the dictionary to the user .

In this embodiment, when the voiceprint matching object is selected from the voiceprint matching object corresponding to the registered voiceprint information in the registered voiceprint information database stored in the voiceprint lock, a further round of voiceprint matching is required. Authentication, that is, two rounds of voiceprint authentication are required in this authentication stage, so that the registered voiceprint information database in the voiceprint lock can be updated and maintained at the same time as the voiceprint authentication, so as to improve the security of the voiceprint lock.

Wherein, the unregistered voiceprint matching object in the dictionary is selected from the dictionary database stored in the voiceprint lock and any voiceprint matching object that has no corresponding registered voiceprint information in the registered voiceprint information database.

After determining the unregistered voiceprint matching object in the dictionary, the main control device 210 outputs the perception information of the unregistered voiceprint matching object in the dictionary through the perception information output device 250 .

Step 650: In response to the voiceprint lock collecting the first feedback voice for the perception information of the unregistered voiceprint matching object in the dictionary, determine the first voiceprint information to be recognized in the first feedback voice.

Afterwards, the main control device 210 collects the perception information for the unregistered voiceprint matching object in the dictionary through the voice collection device 220, and determines the feedback voice, which is the "first feedback voice" in this embodiment, and further determines the first feedback voice. The voiceprint information in the voice is recorded as "the first voiceprint information to be recognized".

Step 660: Perform voiceprint matching on the first to-be-recognized voiceprint information and the currently successfully matched registered voiceprint information, and determine the matching result obtained from the current voiceprint matching.

Wherein, the registered voiceprint information that is currently successfully matched is: the registered voiceprint information in the registered voiceprint information database that is successfully matched with the voiceprint information to be identified. Afterwards, perform voiceprint matching on the first voiceprint information to be recognized and the registered voiceprint information used for voiceprint matching in step 630, and determine the matching result obtained from the current voiceprint matching. That is, in the two rounds of voiceprint authentication in this authentication stage, the voiceprint information to be recognized in the first round of voiceprint authentication has been successfully matched with the registered voiceprint information in the registered voiceprint information database (such as steps 630, 640), Perform voiceprint matching on the first to-be-recognized voiceprint information of the unregistered voiceprint matching object in the dictionary in the second round of voiceprint authentication and the successfully matched registered voiceprint information in the first round of voiceprint authentication, and obtain the matching result.

Step 670: In response to the matching result of the current voiceprint matching indicating that the first voiceprint information to be recognized is successfully matched with the registered voiceprint information that is currently successfully matched, the first voiceprint information to be recognized is As the registered voiceprint information corresponding to the unregistered voiceprint matching object in the dictionary, it is stored in the registered voiceprint information database or the registered voiceprint information in the registered voiceprint information database is updated and maintained.

After the second round of voiceprint authentication is passed, the registered voiceprint information is updated and maintained according to the result of the second round of voiceprint authentication. That is, in response to the matching result indicating that the voiceprint information to be recognized is successfully matched with the registered voiceprint information in the registered voiceprint information database, performing the matching of the registered voiceprint information database based on the voiceprint information to be recognized The update operation includes: in response to the matching result obtained from the current voiceprint matching indicating that the first voiceprint information to be recognized is successfully matched with the registered voiceprint information that is currently matched successfully, updating the first voiceprint information to be recognized The registered voiceprint information is stored in the registered voiceprint information database or updated and maintained in the registered voiceprint information database as registered voiceprint information corresponding to unregistered voiceprint matching objects in the dictionary.

For example, the main control device 210 first selects the voiceprint matching object "Sesame" from the registered voiceprint information database, and outputs the perception information of the voiceprint matching object "Zesame" to the user, and starts the first round of voiceprint authentication. After obtaining the user's feedback voice for the voiceprint matching object "Zhima", and determining the voiceprint information to be recognized in the feedback voice (for a clearer description, denoted as "T1"), the voiceprint information to be recognized T1 and registered The registered voiceprint information corresponding to the voiceprint matching object "Zhima" in the voiceprint information database (referred to as "R1" for a clearer description) is used for voiceprint matching.

After the voiceprint matching object "Zesame" is successfully matched, the main control device 210 selects a voiceprint matching object "Apple" from the dictionary database (the voiceprint matching object "Apple" is not stored in the registered voiceprint information database. , that is, the voiceprint matching object "Apple" has not registered voiceprint information), and output the perception information of the voiceprint matching object "Apple" to the user, and start the second round of voiceprint authentication. After obtaining the user's feedback voice for the voiceprint matching object "Apple", and determining the voiceprint information to be recognized in the feedback voice (for a clearer description, denoted as "T2"), after that, the voiceprint information to be recognized T2 and The registered voiceprint information R1 corresponding to the voiceprint matching object "Zhima" in the registered voiceprint information database performs voiceprint matching, and determines the voiceprint matching result.

If the voiceprint information T2 to be recognized is successfully matched with the registered voiceprint information R1 corresponding to the voiceprint matching object "Sesame" in the registered voiceprint information database, the voiceprint information T2 to be recognized will be used as the voiceprint information corresponding to the voiceprint matching object "Apple". The registered voiceprint information is directly stored in the registered voiceprint information database. If the number of registered voiceprint information stored in the registered voiceprint information database is greater than the preset quantity threshold, delete an original piece of registered voiceprint information according to a preset policy.
