| Outline of Final Research Achievements |
As communication support systems using a sound generator of an electrolarynx for physically handicapped persons, we investigated (1) methods to make a natural voice by controlling intonation, and (2) a human interface device using formant frequencies which have relationship with the tongue and jaw movements. The conclusions of (1) are showed in the following. (a)It was difficult to add immediately an appropriate intonation by finger pressure to an electrolarynx voice. (b)The control parameter by the expiratory flow was clarified. (c) There was a possibility that the head movements were useful for intonation control. The conclusions of (2) are the following. (a)We clarified the range of the formant frequencies by moving the mouse and tongue in detail. (b) We investigated the effect that a state of the vocal cords gave in formants. (c) We showed a possibility that simple movements of the mouth could be used for a mouse pointer.
