Method for personalized television voice wake-up by voiceprint and voice identification

Abstract

The invention discloses a method for personalized television voice wake-up by voiceprint and voice identification, particularly a method for performing identity confirmation on a television user through voiceprint identification and controlling a television to perform personalized voice wake-up through confirmed identity and a voice identification result of user voice, and relates to voiceprint identification and voice identification technologies. A composition system comprises a voice control system (1), an information storage unit (2) and a television main controller (3) which are connected through electric signals. The method has the characteristics of short training time, very high voiceprint and voice identification speed and high identification rate. Voiceprint and voice identification can be finished by only offline training and testing, identification results do not need to be sent to a cloud server, use is convenient, and the safety of family information is guaranteed. The method also can be applied to user-personalized automatic voice channel change of the television, can be transplanted to a common high-speed DSP (digital signal processor) or chip for operation, and can be widely applied to the related fields of smart homes.

Description

technical field [0001] The invention relates to voiceprint recognition and speech recognition technology.

Problems solved by technology

However, due to the variety of dialects in various parts of China, many homophones, different intonations of local dialects, noise in the surrounding environment and other factors, the accuracy of voice recognition is very low, and the phenomenon that the TV cannot execute the user's voice commands often occurs.

Therefore, for consumers, the current voice TV cannot meet their needs to a certain extent.

At the same time, most of these man-machine voice interaction functions need to be completed through cloud computing, and there are certain security risks.

[0003] Now almost every family has one or several TV sets, but one TV is usually used by several family members, especially the TV placed in the living room, and each family member has different preferences for TV program channels Similarly, after turning on the TV, it is usually necessary to use the remote control to traverse and switch the TV program channels to find one’s favorite channel, which is very inconvenient and cumbersome
