Independent formant and pitch control applied to singing voice

[摘要] ENGLISH ABSTRACT: A singing voice can be manipulated artificially by means of a digital computer for thepurposes of creating new melodies or to correct existing ones. When the fundamental frequencyof an audio signal that represents a human voice is changed by simple algorithms,the formants of the voice tend to move to new frequency locations, making it sound unnatural.The main purpose is to design a technique by which the pitch and formants of asinging voice can be controlled independently.
