Abstract

In this paper, an educational mandarin syllable speech recognition and speech corpus system based on Matlab and SQL is introduced. The system includes a set of mixture CDHMM training and recognition algorithms both in Matlab M-files and optimized MEX-files, which can deal with multi-observations and scaling problems; a database toolbox to save and retrieve binary speech samples to and from a SQL database; a real-time speech recording ActiveX control to record speech samples and perform endpoint-detection. The three parts are integrated into Matlab to build up a speech recognition system mainly for educational purposes. It has been used in 408 mandarin syllables speech recognition; and a baseline recognition rate of 91.5% is reached
