Comparison of time-frequency signal analysis techniques with application to speech recognition

Abstract

Techniques for machine recognition of speech exist, but use representations of the speech signal which cannot convey some of the speech information. Alternatives from time-frequency and time-scale analysis are compared with the traditional methods with a view to improving the word recognition rate. Experiments have shown the speech recognition rate improves in some cases.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
