In order to sing in tune, it is necessary to hear amodeled pitch correctly. However, differences in audibility of pitches may arise depending on different sound sources used as exemplars. Previous studies have reported that when one's own familiar voiceis used as a model voice, one is able to sing pitches correctly. In this study, we examined whether learners who were unable to distin-guish pitches fromvoices of others would be able to judge the difference in pitches by using their own voice quality as amodel voice. The results showed thatlearners who could not distinguish all pitches fromvoices of others were able to distinguish all of them correctly with their own voice quality.We thinkthat difference in vocal range and other factors may have contributed to difficulty in hearing when the model sound was from a voice of another person. When the model was their own voice, all they had to focus on was changes in pitch, making it easier for them to notice differences.
