Study on the Articulation Test in Pronunciation in Esophageal Voice

In order to estimate the articulation grade of pronunciation of an esophageal voice, the pronunciation test which had reported by Okamoto and others were undertaken in seven laryngectomized patients who were operated at the Department of Esophagobronchology of the Osaka Red Cross Hospital. The results were as follows:1) Percentage of the correct articulation grade of pronunciation of esophageal voice which can commonly talk with man were between 60% and 70%. This percentage would not be change unless the general condition of the patients become worse. And there were no difference between “talk with man fluently” and “talk with man” in view of study.2) The correct pronounced syllables were /Su/ /So/ /Na/ /Chu/ and /Nya/, and the incorrect pronounced syllables were /Ha/ /Ho/ /Hyu/ /Hi/ and /He/.3) In order to estimate the correct articulation grade of pronunciation of esophageal voice, the author had selected 100 Japanese syllables. And from this study, it would be available better to select Taguchi's test words.
