The tactile channel is the only communication channel available for the speech and deaf-blind people. The common used communication methods are based on a hand contact between the handicapped person and the others; this communication is obviously possible only at short distance. Another communication method is based on the Braille code; this is possible only if both the parties in conversation have a dedicated terminal namely, the handicapped perdon a Braille terminal and the other a terminal for data transmission. In this paper we describe a system that allows a handicapped person to make a telephone communication. The system uses speech processing technologies. Current technology of speech processing allows the automatic text-to-speech convertion with good quality and the automatic recognition of spoken words with low error rates for limited vocabulary (hundred words) and connected speech.

Abstract
The tactile channel is the only communication channel available for the speech and deaf-blind people. The common used communication methods are based on a hand contact between the handicapped person and the others; this communication is obviously possible only at short distance. Another communication method is based on the Braille code; this is possible only if both the parties in conversation have a dedicated terminal namely, the handicapped perdon a Braille terminal and the other a terminal for data transmission. In this paper we describe a system that allows a handicapped person to make a telephone communication. The system uses speech processing technologies. Current technology of speech processing allows the automatic text-to-speech convertion with good quality and the automatic recognition of spoken words with low error rates for limited vocabulary (hundred words) and connected speech.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
