ABSTRACT:
A method and apparatus for generating a new audio segment that is based upon a given audio segment of an audio signal first locates a set of consecutive audio segments in the audio signal. The located set of audio segments precede the given audio signal and have a formant. The formant then is removed from the set of audio signals to produce a set of residue segments having a pitch. The pitch and set of residue segments then are processed to produce a new set of residue segments. Once produced, the formant of the consecutive audio segments is added to the new set of residue segments to produce the new audio segment. The audio signal includes a plurality of audio segments.
