CSS is an integral provider of CapTel captioned telephone service, which enables people who are deaf or hard of hearing to use the phone. Just like captions you’d see on TV, CapTel users see captions during their telephone conversations. The captions ensure that people with hearing loss can use the telephone with confidence, knowing they’ll catch every word that is said. Captions appear in a built-in display on a CapTel phone, or are displayed on a mobile device or computer browser window.
As CapTel users dial a phone number, the captioning service automatically joins the call to provide captions. CapTel users speak and listen directly to the other party, just as they would with any other call. But they also can read word-for-word captions of everything the other party says, courtesy of the captioning service.
