Acoustic parameters of voice individuality and voice-quality control by analysis-synthesis method [link]Paper  doi  abstract   bibtex   
Experiments on voice individuality are reported that made\textbackslashtuse of an analysis-synthesis system capable of modifying\textbackslashtpitch, formant frequencies, & formant bandwidths. A short\textbackslashtnonsense word comprising five short Japanese vowels was\textbackslashtpronounced by male speakers (N = 2) & then subjected to\textbackslashtfour different manipulations: uniform shift for all formant\textbackslashtfrequencies, shift of the lower three formants, shift in\textbackslashtcombinations of two formants, & individual formant shifts.\textbackslashtParallel with these alterations, four bandwidth\textbackslashtmanipulations were effected. Test stimuli were then\textbackslashtpresented to listeners (N = 3) familiar with the two\textbackslashtspeakers, who were asked to identify the speakers' voices.\textbackslashtVoice individuality was found to be more sensitive to\textbackslashtformant shifts than to bandwidth manipulation or pitch\textbackslashtshift.
