采用matlab进行语音处理的软件包

This package contains speech recognition research tools. I implemented
a feature extraction program and three most popular speech recognizers,
i.e., Dynamic time-wrapping algorithm (DTW), Discrete Hidden Markov model
(DHMM) and Continuous HMM with Gaussian mixture density functions (CHMM).
The programs are grouped as:

(A)
     feature -- turn a speech signal to a vector sequence

(B)
     dtwcmp -- dynamic time-wapping (DTW) comparision

(C)  gensym -- transform a feature vector sequence to discrete symbols
     dhmm   -- discrete HMM training program
     dtest  -- DHMM test program

(D)  chmm    -- continuous density HMM training program
     viterbi -- CHMM test program
