Description: An executable HMM speech recognition routines, the implementation of 10 digits recognition program that contains the HMM speech recognition of segmented, MFCC feature extraction, Baum Welch - training, and Viterbi algorithm, through this routine can be very good understanding of the HMM algorithm principle - An executable HMM - -based 10 who researched recogntion program example. This code in the zip file includes segmentation, MFCC feature extraction, Baum - Welch -based re - estimation and Viterbi algorithm involved in HMM. Else much better understand the HMM algorithm and its application for researched recogntion.
