Abstract

An arrangement for providing captioned telephone service is provided which permits persons who are hard of hearing to receive captioning of their telephone communications as they need it. A personal interpreter/captioned telephone device can dial a relay on a second telephone line while the assisted user if conversing with a hearing user over a first telephone line. The second telephone line connects to a relay which provides voice to text translation service and returns a text stream to the captioned telephone device.

initiating a telephone call over a first telephone line between the assisted user and the hearing user;

the assisted user initiating a telephone connection over a second telephone line to the relay;

transmitting the voice of the hearing user over the second telephone line to the relay so that the relay can convert the words of the hearing user into text;

transmitting the text created by the relay back to the station of the assisted user over the second telephone line; and

5. A method for providing captioned telephone service to an assisted user communicating over a first telephone line with a hearing user using a captioned telephone device, the method comprising the steps of

while the assisted user is conversing over the first telephone line with the hearing user, the assisted user operating a control on the captioned telephone device to initiate a captioning service;

the captioned telephone device initiating a telephone connection over a second telephone line to the relay;

the captioned telephone device transmitting the voice of the hearing user over the second telephone line to the relay so that the relay can convert the words of the hearing user into text;

the relay transmitting the text created by the relay back to the station of the assisted user over the second telephone line to the captioned telephone device; and
