This paper reports our investigation of the acoustic effects of vo-cal training for amateur singers and of the contribution of those effects to perceived vocal quality. Recording singing voices before and after vocal training and then analyzing changes in acoustic parameters with a focus on features unique to singing voices, we found that two different FO fluctuations (vibrato and overshoot) and singing formant were improved by the train-ing. The results of psychoacoustic experiments showed that perceived voice quality was influenced more by the changes of FO characteristics than by the changes of spectral characteristics and that acoustic features unique to singing voices contribute to perceived voice quality in the following order: vibrato, singing formant, overshoot, and preparation.
