Wavelets for speech processing
Shubha L. Kadambe · The Journal of the Acoustical Society of America · 1999
This presentation is focused on the application of wavelets for speech. Wavelet analysis was recently introduced to the signal and image processing community. Since then it has been applied to various problems. Robustness is an issue in the case of speech-based systems. Wavelet analysis seems to be one answer for this problem. In this lecture, an overview of what are wavelets and why wavelets are used for speech processing is given. Wavelet-based speech applications such as phoneme recognition and low bit-rate speech compression are discussed. Experimental results are provided to demonstrate the usefulness of wavelet analysis for speech applications.
