Abstract

A method of and system for operating a captioned telephone service, the method comprising the steps of providing words spoken by a remote user to a relay, at the relay, a call assistant listening to the words spoken by the remote user and re-voicing the words into a computer with voice recognition software trained to the voice of the call assistant to create a text stream of the words spoken by the remote user and presenting the text stream to an assisted user via a display.

Claims

I_We. I/We claim:

1. A system for providing captioned telephone service to an assisted user, the system comprising:

a captioned telephone device at the site of the assisted user, the captioned telephone device including a microphone, a visually readable display and a microprocessor;

a relay for converting voice to text, the relay including a computer with voice recognition software and operated by a call assistant, the voice recognition software of the relay trained to the voice of the call assistant to create a text stream of the words spoken by a remote user, the text stream being transmitted to captioned telephone device;

the microprocessor programmed to operate the device to, receive the voice of a hearing user via the microphone, transmit the received voice to the relay, receive the text stream transmitted by the relay and present the text stream via the display for viewing by the assisted user.

2. The system of claim 1 wherein the captioned telephone device further includes an input device to enable the assisted user to enter text and a speaker, the microprocessor further programmed to transmit the text entered by the assisted user to the relay, the relay also for converting the text received from the captioned telephone device into an audible message and transmitting the audible message to the captioned telephone device, the microprocessor further programmed to generate the audible message via the speaker.

3. The system of claim 2 wherein the relay includes a speaker and a microphone linked to the microcomputer, the speaker for presenting the voice of the hearing user to a call assistant at the relay, the call assistant speaking in voice the same words that the call assistant hears spoken by the hearing person into the microphone.

4. A method of operating a captioned telephone service, the method comprising the steps of:

providing words spoken by a remote user to a relay;

at the relay, a call assistant listening to the words spoken by the remote user and re-voicing the words into a computer with voice recognition software trained to the voice of the call assistant to create a text stream of the words spoken by the remote user; and

presenting the text stream to an assisted user via a display.
