Research Abstract

Many aspects of the sound of a pneumatic artificial larynx have hitherto not been improved. Recently, the development and its trial production of the "new type artificial larynx" were carried out by our project.
Results may be summarized as follows:
(1) While the original sounds of substitutive vocal cords of the existent artificial larynx were confined to low frequency bands from 500 to 1200 Hz, those of the "New type artificial larynx" include a wide frequency from 250 to 7000 Hz.
(2) Speech sounds of the "New apparatus" were excel in degree of clarity compared with those of the past instrument.
(3) In the "New apparatus", the aluminum foil (vibratory valve) was substituted for rubber membrane of the existent Tapia's larynx. The former have considerable durability.
(4) The original wave forms of the Japanese vowels(/a/,/i/,/u/,/e/,/o/),by means of the "New artificial larynx",were improved remarkably and also they were very similar to those in the normal speech sounds.
(5) Some consonants([ts],[p],[m]) were exactly articulated in the "New instrument".
(6) By use of the "New artificial larynx",the sonagrams of the speech sound were improved strikingly and resembled those of the normal subject.
It seems to suggest that the result of the clinical test have a possibility of a practical use.
