Relay Conference Captioning (RCC)

Relay Conference Captioning (RCC) is a free service for anyone who is deaf or hard of hearing to engage in meetings (in-person or remote), group conversations in a videoconference and multi-party conference call. Using the same high-quality captioners that produce closed captioning for television, RCC users receive live, real-time text streamed to a computer connected to the Internet anywhere.
