    Abstract: A method of operating a captioned telephone call in which an assisted user's (AU's) captioned device is connected by a first line to a hearing user's (HU's) device and by a second line to a relay providing captioning for a conversation is disclosed. The method includes capturing an AU's voice signal via a microphone, transmitting the voice signal from the captioned device to the HU's device on the first line, obtaining a combined voice signal including both users' voice signals from the first line at the captioned device, cancelling the AU's voice signal from the combined signal to generate an independent HU voice signal, broadcasting the HU's voice signal via a speaker, transmitting the independent HU's voice signal to the relay, receiving captions at the captioned device from the relay corresponding to the HU's voice signal, and presenting the captions as text on a display screen.

    Abstract: A method of operating a captioned telephone call in which an assisted user is connected by a captioned telephone device that is connected both by a first line to a remote user and a second line to a relay providing captioning for a conversation, the method comprising the steps of: when a start of an incoming call is detected by the captioned telephone device on the first line, the captioned telephone device automatically calling the relay on the second line to initiate captioning service set up; the captioned telephone device passing spoken words received on the first line to the second line; and the relay then providing text captions of the spoken words back to the captioned telephone device on the second line.
