| 抄録: | It is difficult for the deafblind, or the hearing impaired, to control the pitch of their
voice because they cannot perceive it. In particular, when singing, it is very difficult for them
to control the pitch of their voice because they need to maintain a stable tone. We have developed
a voice pitch control system to assist their singing by means of a tactile display. Using this
tactile feedback system, we verified in a previous study that two deafblind subjects were able
to control the pitch of their voices with as much accuracy as hearing children. By using this
tactile feedback system, the correspondence between musical scale and proprioceptive sensation
(muscular sensation, and so on) of the two subjects was returned to pre-hearing loss levels. They
sung using not only tactile feedback but also proprioceptive feedback. In this paper, we investigate
the ability of hearing subjects to control the pitch of their voice using our tactile feedback
system, but without auditory feedback. Seven hearing participants were examined under two
conditions—“without tactile feedback” and “with tactile feedback”—to ascertain their abilities
to control their pitch while subjected to a masking noise. The results indicated that hearing
subjects could not sing with an accurate pitch using only the proprioceptive feedback (“without
tactile feedback” condition). |
