Telephone Communication for the Deaf

The deaf currently communicate over the telephone network through the use of teletypes or CRT terminals. These aids, while of great benefit to individuals so equipped, do not permit communication with persons not owning special equipment. A device presented here provides telephone communication for the deaf without requiring special equipment at the hearing party's location. The aid operates via tones received from a standard Touch Tone (TM) telephone which greatly expands potential telephone usage for the deaf.
