Establishment of speech test using a speech recognition unit. Part 1. The utility of the speech recognition unit.

Abstract

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,

“…However, because of the confounding by auditory psychological factors, these measures were not sufficiently reliable for objective assessments. 16,21,22 Such confounding by auditory psychological factors can be eliminated by using a speech recognition system with personal computers.…”
