Abstract

The invention discloses a man-machine interactive system and method for digital television voice recognition. The system comprises a target voice acquisition module, a voice analysis module, a semantic computation module and an intelligent control module, wherein the target voice acquisition module comprises a signal amplification module, a forward filtering module, a signal sampling module and a data compression and coding module; and the voice analysis module comprises a noise removal module, a feature extraction module and a decoding device. The method comprises the processes of target voice acquisition, voice noise removal, voice recognition processing, command recognition conversion and intelligent control processing. In the invention, through the cooperative work of the modules, a digital TV man-machine interactive technology for anti-interference voice intelligent identification and voice analysis and interaction under the digital TV reverberation acoustic environment of digital home life is achieved, and an advanced digital TV voice language interaction mode is provided.

Description

technical field [0001] The invention relates to the technical field of voice processing and semantic recognition, and the technology of intelligently analyzing, processing and collecting voice by computer, in particular to a digital TV voice recognition human-computer interaction system and method. Background technique [0002] Speech recognition technology is mainly a technology that allows machines to convert voice signals into corresponding text or commands through recognition and understanding. Speech recognition technology extracts the features of the voice through the collection and input of the voice, and then uses the voice information features of the model database to perform pattern matching, and converts the information contained in the voice into text or commands. [0003] According to the different objects of speech recognition, speech recognition characters can be roughly divided into three categories: isolated word recognition, keyword recognition and continuo...
