The TET system uses the system of voice-to-text relays, already in existence to assist the deaf community communicate with hearing persons over the telephone, to translate the spoken voice into a text stream. The TET relay and TET device are capable of separating voice and digital communications frequencies carrying text so that voice and a text communications stream of the words spoken by the voice can be carried over a common telephone line.
