Abstract

A system is described for assisting the hard of hearing in the use of the telephone, the system termed here text enhanced telephony or TET. The hard of hearing user uses a TET device or appliance which permits the user to speak and to hear the words spoken by the other party, the TET device also supplying to the user a text character stream of the words spoken by the other party. 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. The devices can also be capable of automated capabilities such that the devices can automatically configure a three-party relay call without the need for the user'"'"'s instructions.

Claims

1. A method of providing a text transcription of speech spoken over a telephonic connection between a user and a relay which includes speech to digital text communications conversion capability, the method comprising the steps of

providing the user with a communication station that can display digital text visually and that can separate digital text communications from spoken voice transmitted over the telephonic connection;

connecting the station through the telephonic connection to the relay; and

at the relay, creating a digital communication text transcription of spoken words and transmitting both the digital communication text transcription and the spoken words simultaneously over the single telephonic connection to the station which displays the text transcription for the user so that the user will receive both the spoken words and the visual display of the text transcription.
