ABSTRACT:
A class of methods and related technology for determining the phase of each harmonic from the fundamental frequency of voiced speech. Applications of this invention include, but are not limited to, speech coding, speech enhancement, and time scale modification of speech. Features of the invention include recreating phase signals from fundamental frequency and voiced/unvoiced information, and adding a random component to the recreated phase signal to improve the quality of the synthesized speech.
