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.
