Abstract

<p>It is difficult for the deafblind or the hearing impaired persons to control their voice pitch because they cannot perceive their voice pitch. Especially in case of singing a song it is very difficult for them to control their one because they must keep a musical tone in stably. A voice pitch control system is developed to assist their singing by using a tactile display. The tactile display is equipped with sixty-four piezoelectric vibrators in four rows. There are sixteen piezoelectric vibrators in each row which is corresponded to semi tone of equal temperament of 12 degrees. User put his/her the last joint of index finger on the tactile display to receive tactile stimuli. First and second row from the right side show voice pitch frequency. Third and fourth row show teaching musical scale. If voice pitch frequency is corresponded to a teaching musical scale user perceive a straight line. In this paper we describe the voice pitch control system which we developed and its evaluation.</p>
