MOBILE TALK-BACK SYSTEM FOR DEAF AND DUMB PEOPLE

摘要

FIELD: information technology. ^ SUBSTANCE: mobile talk-back device placed on the palm of the hand has an infrared receiver, an infrared transmitter and a speech synthesiser. The glasses have two synchronously operating infrared receivers lying separately on the right and left ear hooks of the glasses, and two synchronously operating infrared transmitters lying separately on the right and left ear hooks of the glasses. Two synchronously operating infrared receiver and transmitter of the glasses interact through an infrared communication channel with the mobile talk-back device. There is an external acoustic device which serves to playback program-synthesised speech. Three infrared transmitters have diaphragms which are movable along the axis of the conical flux of infrared radiation serve to change the value of the solid angle of the conical flux of infrared radiation. ^ EFFECT: high quality of received speech sounds. ^ 2 cl, 2 dwg
