Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The flow of the speech recognition method for the smart television provided by the invention is as shown in fig. 1, the flow of the preferred embodiment of the speech recognition method for the smart television of the invention is as shown in fig. 1, and the speech recognition method for the smart television of the invention comprises the following implementation steps:
and step S100, the intelligent television receives a voice instruction of user interactive operation.
In a family using the smart television, accents of users who are members of the family are different from each other, even different dialects may be used, although the dialects can be recognized by the existing smart television in the voice recognition function, in the operation process, when the users use the dialects to interact with the smart television, the voice recognition technology of the smart television cannot directly determine the dialects of the users, and the dialects which are selected by the users need to be selected by the users, that is, the smart television cannot directly recognize the dialects of the users, so that voice recognition is performed. The method of the invention can directly receive dialect interactive voice instruction of the user in the process of using voice recognition of the intelligent television to carry out man-machine interactive operation, of course, as another preferred embodiment, the intelligent television can create a corresponding voiceprint characteristic file for the user in advance to automatically select the dialect of the user and directly carry out recognition, and before the intelligent television receives the voice instruction of the user interactive operation, the method can also comprise the following steps:
the method comprises the steps that the smart television creates a corresponding voiceprint feature file for each user in advance; and the user selects and confirms the dialect type in the corresponding voiceprint feature file.
The smart television establishes voice print characteristic files for family member users in advance according to respective dialects so as to ensure that a corresponding dialect voice recognition scheme can be directly selected for recognition according to the dialects in the subsequent smart television voice recognition process, and therefore, the user voice print characteristic files also need to be correspondingly selected for the dialects.
Step S200, the voiceprint recognition module determines the dialect type used by the user according to the voiceprint characteristics of the voice command of the user interactive operation.
Specifically, the voiceprint recognition module performs voiceprint recognition on a voice instruction of user interactive operation, and confirms the user according to a voiceprint feature file of the user established in the intelligent television in the process, so that the dialect used by the user can be directly determined. For example, a dialect speaking user (Cantonese) says "I want to watch XX programs" in front of the TV for the first time, and then the TV interface pops up various dialects according to the prior art: the dialect recognition results of the Cantonese, the Sichuan and the Hunan languages are given to the user, and the user needs to further judge the dialect to be the type of the Cantonese, and then the television can carry out the subsequent voice recognition operation. When the method is adopted, a dialect-speaking user (Guangdong dialect) says that the user wants to watch XX programs before a television for the first time, at the moment, various dialects cannot be popped up on a television interface for the user to select and confirm the dialect types before carrying out next voice recognition, and the user is confirmed through a voiceprint recognition module, directly selects the dialect types of the user to be matched, and then adopts a voice recognition scheme of the Guangdong dialect for recognition.
Certainly, as another preferred embodiment, the voiceprint recognition module can also be implemented by using a voiceprint recognition server connected to the smart television network, and the smart television can store more user voiceprint feature information by using the voiceprint recognition server connected to the smart television network.
Step S300, the voice recognition module directly converts the voice command of the user interactive operation into characters according to the dialect type used by the user so as to recognize the voice command of the user.
In the same way as the voiceprint recognition module, the voice recognition module can also be realized by adopting a voice recognition server connected with the intelligent television network, and in the same way, the intelligent television can store more voice recognition schemes by adopting the voice recognition server connected with the intelligent television network, and can also be continuously expanded and updated as required.
The method of the invention adopts the voiceprint feature recognition technology to distinguish the users in the family using the intelligent television, and directly carries out voice recognition according to the preset dialect of the user, thereby realizing the automatic dialect voice matching in the voice recognition process of the intelligent television.
Fig. 2 shows a schematic structure diagram of a preferred embodiment of the speech recognition system of the smart television, where the speech recognition system 60 of the smart television includes a speech receiving module 61, a voiceprint recognition module 62, and a speech recognition module 63.
The voice receiving module 61 is used for the smart television to receive a voice instruction of user interactive operation. In a family using the smart television, accents of users who are members of the family are different from each other, even different dialects may be used, although the dialects can be recognized by the existing smart television in the voice recognition function, in the operation process, when the users use the dialects to interact with the smart television, the voice recognition technology of the smart television cannot directly determine the dialects of the users, and the dialects which are selected by the users need to be selected by the users, that is, the smart television cannot directly recognize the dialects of the users, so that voice recognition is performed. The system of the present invention can directly receive dialect interactive voice instructions of the user during the process of performing human-computer interaction operation by using voice recognition of the smart television, and certainly, as another preferred embodiment, the smart television can create corresponding voiceprint feature files for the user in advance to automatically select the dialect of the user and directly perform recognition, that is, the system 60 further includes a user voiceprint feature module 64 for creating corresponding voiceprint feature files for each smart television user in advance and including dialect types corresponding to the voiceprint features of the user.
The smart television establishes voice print characteristic files for family member users in advance according to respective dialects so as to ensure that a corresponding dialect voice recognition scheme can be directly selected for recognition according to the dialects in the subsequent smart television voice recognition process, and therefore, the user voice print characteristic files also need to be correspondingly selected for the dialects.
The voiceprint recognition module 62 is configured to determine a voiceprint feature of the voice instruction of the user interaction operation received by the voice receiving module 61 and determine a dialect category used by the user.
Specifically, the voiceprint recognition module 62 performs voiceprint recognition on a voice instruction of user interactive operation, and confirms the user according to the voiceprint feature file of the user established in the smart television in the above process, so as to directly determine what dialect the user uses, unlike the prior art that when the smart television receives the interactive operation voice of the dialect of the user, the user needs to select the dialect again to perform voice recognition of the next step, the system of the present invention can directly confirm the voice recognition scheme according to the dialect of the user, thereby skipping the dialect selection process and improving the experience of the user in using the voice recognition technology. For example, a dialect speaking user (Cantonese) says "I want to watch XX programs" in front of the TV for the first time, and then the TV interface pops up various dialects according to the prior art: the dialect recognition results of the Cantonese, the Sichuan and the Hunan languages are given to the user, and the user needs to further judge the dialect to be the type of the Cantonese, and then the television can carry out the subsequent voice recognition operation. When the system is adopted, a dialect-speaking user (Guangdong dialect) says that the user wants to watch XX programs before a television for the first time, at the moment, various dialects cannot be popped up on a television interface for the user to select and confirm the dialect types before carrying out next voice recognition, and the user is confirmed through a voiceprint recognition module, directly selects the dialect types of the user to be matched, and then adopts a voice recognition scheme of the Guangdong dialect for recognition.
Certainly, as another preferred embodiment, the voiceprint recognition module can also be implemented by using a voiceprint recognition server connected to the smart television network, and the smart television can store more user voiceprint feature information by using the voiceprint recognition server connected to the smart television network.
The voice recognition module 63 is configured to directly convert the voice of the user into characters according to the dialect type corresponding to the voice command voiceprint feature of the user interaction operation recognized by the voiceprint recognition module 62, so as to recognize the voice command of the user.
In the same way as the voiceprint recognition module, the voice recognition module 63 can also be implemented by using a voice recognition server connected with the smart television network, and in the same way, the smart television can store more voice recognition schemes by using the voice recognition server connected with the smart television network, and can also be continuously expanded and updated as required.
The invention also provides a readable storage medium, wherein the readable storage medium stores a program for intelligent television voice recognition, and the steps of the intelligent television voice recognition method are realized when the program for intelligent television voice recognition is executed by a processor. The specific execution process of the program is the same as the preferred implementation of the above-mentioned speech recognition method for the smart television, and is not described herein again.
It should be understood that the above-mentioned embodiments are merely preferred examples of the present invention, and not restrictive, but rather, all the changes, substitutions, alterations and modifications that come within the spirit and scope of the invention as described above may be made by those skilled in the art, and all the changes, substitutions, alterations and modifications that fall within the scope of the appended claims should be construed as being included in the present invention.
