title: Experimental modification of the Western Electric No. 5 electrolarynx to a mouth-type instrument.
abstract: A modification of the Western Electric No; 5A electrolarynx is described and evaluated. The modification involved insertion of a bypass plug into the circuitry of this necktype instrument thus converting it to a mouth-type electrolarynx. Intensity readings at the one-third octaves and intelligibility data were obtained with the modified instrument and with a Cooper-Rand electrolarynx. The instruments were judged to be equal in overall performance.
