CaptionCall Mobile empowers deaf and hard-of-hearing individuals to make and receive phone calls with instant live captions. CaptionCall Mobile offers captioned phone calls in real-time at no cost to qualified deaf and hard-of-hearing users in an easy-to-use mobile app that integrates seamlessly into daily life and work.

Why CaptionCall?

No more landlines. CaptionCall Mobile goes where you go, allowing you to make and receive captioned calls from your mobile device anywhere with WiFi or mobile data service.

Fast, accurate, and easy, CaptionCall automatically transcribes both sides of your conversation in a customizable easy-to-read format, using advanced voice to text for deaf and hard-of-hearing that is 100% private and secure.

Accurate call captions appear in real-time for free-flowing, natural conversation.

No cost, ever. As an FCC-approved captioned call service, CaptionCall provides 100% no-cost call captioning to those with qualified hearing loss, thanks to a federally-administered fund.


1. Install the CaptionCall Mobile app

2. Create an account. You must provide accurate account information to meet federal requirements and enable your service.

3. Receive your new CaptionCall Mobile phone number for making and receiving captioned calls. Or you can continue using your existing phone number and automatically forward them to CaptionCall Mobile on your mobile device or tablet for captioning.

4. Tap “Allow” when asked to grant permissions to CaptionCall Mobile. You'll have quick access to your saved contacts, captioned voicemail and voicemail alerts, and can dial and receive calls from any phone number, just like your regular phone.

5. Use CaptionCall Mobile to start making calls with instant live captions.

CaptionCall Mobile is exclusively for people with hearing loss who need captions to use the phone effectively in the United States only.

CaptionCall and CaptionCall Mobile are available in the United States only. FEDERAL LAW PROHIBITS ANYONE BUT REGISTERED USERS WITH HEARING LOSS FROM USING INTERNET PROTOCOL (IP) CAPTIONED TELEPHONES WITH THE CAPTIONS TURNED ON. IP captioned telephone service may use a live operator. The operator generates captions of what the other party to the call says. These captions are then sent to your phone. There is a cost for each minute of captions generated, paid from a federally administered fund. No costs are passed along to individuals who qualify for the service. The CaptionCall phone and app remain the property of Sorenson in order to provide ongoing support, service, and upgrades. Patent information:

95% deaf without hearing aids and I can now converse with fam and friends!

I am a long time user of relay calls for the deaf via sprint and then T-Mobile. The only problem was I had to use my desktop and who wants to sit at a desktop waiting for calls to come in? Not me! For a while the sprint relay app would let you dictate what you wanted to say, but then they got rid of that feature, forcing us to type in what we wanted to say. Many times people (of course the people I didn't know, not my friends) would hang up on me because I took too long to type!

Olelo cleared up all the issues and I can now SPEAK to the person I want to communicate with and I can READ what they are saying! It's miraculous! 100% accurate and very fast in real time transcribing to me what is being said. I love this app! It's a game changer and a life changer

For anyone who is hearing impaired or deaf, this is the app to use! I'd give it 10 stars if there were 10. Thank you very much to the developers of Olelo and congratulations on being acquired (or partnered with) by Sorensen!

Once a struggle, now after some updates it is amazing…

As I was tapping out a reply to the chat help person, I received my first Olelo call and the captioning and speed was ah-may-zing. Perfect. Both speed and accuracy. I even asked the caller if he could give me his impression of the delay in conversation while the speech-to-text was occurring and he said “there wasn’t any delay, I wouldn’t have even known…” That, is incredible. I’m late deafened (profoundly) and was a SpEd Technologist responsible for Accommodations and Adaptations for students and have looked at and used so many options as I am not proficient at ASL. Hamilton, InnoCaption, Ava, none of these were even close to the accuracy and speed of my first Olelo use. It was a pleasure talking on that call. Like I am still smiling. Thank you so much. Once the personalized voicemail greeting issue is figured out this app will blow away the other options.

Good App - Needs One Thing

This is a great caption app I always love the captioning of both ends for historical purposes and recall. Very handy. I didn’t find any way to quickly adjust the tone of the speakers voice from within the app. My hearing impairment make it difficult to hear deeper male voices. So some method of tone manipulation to increase the clarity for those that need it or either end of the spectrum of sound and impairment. That is the one thing I can think of at this first testing that would be a great improvement. Might I suggest something easy like Tone: High, Mid, Low to start. Then as development progresses you could add in the settings a way to input your own audio gram to that the tone is lost customized. But start with the easy and work out the other later. I’ve used every method of captioning and apps. I’m always willing to help in development and testing of possible betas for your profound hearing impaired users as someone with an IT background and Great understanding of the current technologies available for the hearing impaired and captioning. Much appreciated feel free to reach me. - David /. If I missed the current way to do the tone manipulation, just let me know. Thanks.
