Captioned Calls with Confidence

Enjoy advanced call captioning at no cost if you have hearing loss that makes live captions necessary to use the phone.

Closed Caption Phone Calls for Your Landline and Mobile

Remember when phone calls were fun? It was a way to connect with people you care about, make plans, check things off your to-do list, and get answers quickly…before hearing loss made the phone frustrating.

You can use either — or both — at no cost if you have hearing loss that makes captions necessary to use the phone. 

Both CaptionCall and Olelo support English and Spanish call captioning as well as an English or Spanish user interface.
