A speech synthesizing software on a PDA for Japanese with speech impairments

摘要

We developed a Japanese language, rapid synthesizing software application for use on a personal digital assistant (PDA). it has an unrestricted vocabulary and can synthesize words and sentences within three seconds. Eight thousands common sentences and words can be pre-registered. By touching the first character at the head of a pre-registered sentence or word from an on-screen Kana (Japanese alphabet) chart, the user can select the sentence or word to be spoken. Characters on the Kana chart can also be input sequentially. Three Japanese with speech impairments rated the device highly for its portability and quick response. Whereas communication previously had to be done by writing or sign language, it was easy for listeners with or without specialized training in communication with persons with speech impairments to understand the output from this device, making conversation easier, which in turn improved the quality of life and social activity of these persons with speech impairments.
