Description: In this article the authors normalize the speech signal based on the publicly available AN4 database. The authors added to the algorithm of calculating the MFCC coefficients, the normalization procedure, that uses pitch of the voice. As demonstrated by empirical tests authors were able to improve speech recognition accuracy rate of about 20%.
