Problems solved by technology

[0003] However, there are still relatively large defects in the existing speech recognition system, which cannot ignore the influence of some characteristics of the surrounding environment and the user's own factors, so that it will not be recognized; therefore, it does not meet the existing needs. We propose a speech recognition system and method for character search based on a speech chip

Abstract

The invention discloses a character search voice recognition system and method based on a voice chip, and belongs to the technical field of voice recognition. According to the character search voice recognition system and method based on the voice chip, static feature extraction and dynamic feature extraction are included, the input end of the static feature extraction and the input end of the dynamic feature extraction are connected with the output end of voice preprocessing, and the input end of the voice preprocessing is connected with the output end of voice signal acquisition. In order to solve the problem that an existing voice recognition system still has large defects and cannot neglect some feature influences of surrounding environment and user own factors so that recognition cannot be performed, the system performs recognition search on the dynamic audio, and if the search is not performed, the dynamic audio can be recognized and searched. The system adjusts the dynamic audio in a reasonable range and performs secondary identification search if the audio is matched with the audio, and performs detailed comparison and judgment if the audio is matched with the audio, so that the voice identification capability can be improved.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a speech recognition system and method for character search based on a speech chip. Background technique [0002] The application of speech recognition system can be divided into two development directions: one is the continuous speech recognition system with large vocabulary, which is mainly used in computer dictation machines, and the voice information query service system combined with the telephone network or the Internet. It is realized on the computer platform. Another important development direction is the application of miniaturized and portable voice products, such as dial-up on wireless mobile phones, voice control of automotive equipment, smart toys, remote control of home appliances, etc. These application systems Most of them are implemented using special third-party software, especially the emergence of special chips for speech signal processing and speec...
