FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON. Automatic speech recognition software generates captions of what the other party to the call says, and, in certain circumstances, a live communications assistant may be included on the call to make needed corrections and/or add call details. There is a cost for each minute of captions generated, paid from a federally administered fund. No cost is passed on to the CapTel user for using the service. CapTel captioning service is intended exclusively for individuals with hearing loss. CapTel® is a registered trademark of Ultratec, Inc.
