Application background The kit can be used in some speech recognition, speaker recognition, speech synthesis and speech recognition technology, some of the required function, I also used some, for some theoretical research, you can call directly in the MATLAB, the code is very good, spent a lot of effort to find food, here with you under the share. Key Technology In speech recognition, speaker recognition can reference, it includes a lot of related functions, we can be directly used to call, for example in the preprocessing stage of speech recognition, such as frame, short detection, zero crossing rate code,
