61. A system for providing captioned services to an assisted user communicating with a hearing person, the system comprising: a relay for providing a captioning service, the relay including a relay computer, a relay input device and a relay display screen; an assisted user's captioned device comprising: (i) a captioned device processor; (ii) a visual display in communication with the captioned device processor; (iii) a microphone for receiving voice signals from the assisted user using the captioned device; (iv) a speaker for broadcasting voice messages received by the captioned device to the assisted user substantially in real time as voice messages from the hearing person are received at the captioned device; (v) a caption switch in communication with the captioned device processor, the caption switch controllable by the assisted user to indicate that a captioning service should be invoked; the captioned device configured to perform the steps of: (i) establishing the first communication link between the assisted user's captioned device and the hearing person; (ii) obtaining voice signals from the assisted user via the microphone; (iii) transmitting the assisted user's voice signals from the captioned device to the hearing person via the first communication link; (iv) receiving voice signals from the hearing person on the first communication link; (v) broadcasting the voice signals from the hearing person via the speaker to the assisted user; (vi) detecting activation of the caption switch to invoke the captioning service; (vii) in response to activation of the caption switch: (a) transmitting the voice signals received at the captioned device from the hearing person to the relay via the second communication link; (b) receiving text from the relay via the second communication link; and (c) displaying the text received from the relay via the visual display; the relay configured to perform the steps of: (i) transcribing the words spoken by the hearing person into a text message stream; (ii) displaying the text message stream on the relay display screen used by a call assistant; (iii) receiving corrections to the text message stream entered by a call assistant using the relay input device to generate corrected text; and (iv) transmitting the corrected text to the captioned device processor to be presented via the visual display to the assisted user; wherein the caption switch is activatable subsequent to broadcasting at least some voice signals from the hearing person to set up the captioning service while a voice call between the assisted user and the hearing person is on going.
61. A system for providing captioned services to an assisted user communicating with a hearing person, the system comprising: a relay for providing a captioning service, the relay including a relay computer, a relay input device and a relay display screen; an assisted user's captioned device comprising: (i) a captioned device processor; (ii) a visual display in communication with the captioned device processor; (iii) a microphone for receiving voice signals from the assisted user using the captioned device; (iv) a speaker for broadcasting voice messages received by the captioned device to the assisted user substantially in real time as voice messages from the hearing person are received at the captioned device; (v) a caption switch in communication with the captioned device processor, the caption switch controllable by the assisted user to indicate that a captioning service should be invoked; the captioned device configured to perform the steps of: (i) establishing the first communication link between the assisted user's captioned device and the hearing person; (ii) obtaining voice signals from the assisted user via the microphone; (iii) transmitting the assisted user's voice signals from the captioned device to the hearing person via the first communication link; (iv) receiving voice signals from the hearing person on the first communication link; (v) broadcasting the voice signals from the hearing person via the speaker to the assisted user; (vi) detecting activation of the caption switch to invoke the captioning service; (vii) in response to activation of the caption switch: (a) transmitting the voice signals received at the captioned device from the hearing person to the relay via the second communication link; (b) receiving text from the relay via the second communication link; and (c) displaying the text received from the relay via the visual display; the relay configured to perform the steps of: (i) transcribing the words spoken by the hearing person into a text message stream; (ii) displaying the text message stream on the relay display screen used by a call assistant; (iii) receiving corrections to the text message stream entered by a call assistant using the relay input device to generate corrected text; and (iv) transmitting the corrected text to the captioned device processor to be presented via the visual display to the assisted user; wherein the caption switch is activatable subsequent to broadcasting at least some voice signals from the hearing person to set up the captioning service while a voice call between the assisted user and the hearing person is on going. 63. The system of claim 61 wherein the relay is remote from each of the assisted user's captioned device and the hearing person.
