摘要
A method and system that improves voice recognition by improving the voice recognizer of a voice recognition system 10. Mu-law compression 20 of bark amplitudes is used to reduce the effect of additive noise and thus improve the accuracy of the voice recognition system. A-law compression 21 of bark amplitudes is used to improve the accuracy of the voice recognizer. Both mu-law compression 20 and mu-law expansion 22 can be used in the voice recognizer to improve the accuracy of the voice recognizer. Both A-law compression 21 and A-law expansion can be used in the voice recognizer to improve the accuracy of the voice recognizer.
