Abstract

The present invention discloses a phonetic recognition method includes the specific steps of: recording standard phonetic data in phonetic data base; indexing and selecting standard voice segment to be displayed, prompted or broadcast; outputting standard voice segment, inputting new voice segment; recognizing through comparing the input voice signal and that in the data base; judging and feedback displaying. The present invention utilizes the recognizable and un-recognizable voice simultaneously in accurate judgment.

Description

technical field [0001] The invention relates to a voice recognition method, which is mainly used in the fields of voice control system and man-machine dialogue. Background technique [0002] Existing speech recognition technology mainly utilizes the recognizability of speech, and the speech recognition system performs corresponding operations according to speech signals input from the outside. When the voice recognition system can recognize the external voice signal, the voice recognition system will perform the corresponding operation; when the voice recognition system cannot recognize the external voice signal, the voice recognition system will either ignore it, or make a wrong understanding and perform the wrong operation. That is, the speech recognition system can recognize correctly only when the correct speech signal is input, and the speech recognition system cannot recognize and judge the wrong input.
