Captel is for individuals with significant hearing loss who are able to use their own voice, but are unable to effectively use amplification for phone communications.

When using a CapTel phone, the other party's spoken conversation is displayed word-for-word (almost simultaneously) in an easy-to-read window. After dialing, CapTel automatically connects to a local captioning operator (behind the scenes) who transcribes everything the other party says into written text using state-of-the-art voice recognition systems.
