To assess speech disturbances caused by newly made prostheses, visual and acoustical methods, palatograms, sound spectrograms, etc., have been used. But the analysis and assessment requires somewhat professional knowledge and experience and much time, so such methods are not necessarily easier, and have the defect of being somewhat subjective. The purpose of this study is to develop a new speech test that is easy to use and more objective using the speech recognition unit.First, experimental palatal plates were made for a dentulous subject, and the utility of the speech recognition unit was estimated. The speech recognition unit and ordinary hearing were compared in utterance of ten Japanese monosyllables, /sa/, /ta/, /ki/, /hi/, /si/, /ci/, /ni/, /mi/, /ri/, /cu/. Results : 1. The speech recognition unit made mistakes similar to ordinary hearing. 2. The recognition point that is output by the speech recognition unit corresponded well to speech clarity except some cases. 3. The speech recognition unit could detect the changes of consonant frequencies relatively well.
