Comparison of time-frequency signal analysis techniques with application to speech recognition
A. Reilly, B. Boashash · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
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.
