ABSTRACT:
A method for processing a voiced speech waveform when the periods and amplitudes thereof may be non-uniform so that the intelligibility thereof is adversely affected. In accordance with such method successive portions of the speech waveform are processed so that each portion has a substantially uniform period and the intelligibility thereof is enhanced. In some instances the processing may be such as to provide in addition substantially uniform peak amplitudes in each processed portion. The voiced speech waveform enhancement technique may further be used in conjunction with methods for processing unvoiced speech waveforms so as to enhance the intelligibility thereof.
