InnoCaption empowers you to call anyone, day or night, with fast and accurate real-time captioning. If your hearing loss makes understanding your cell phone calls difficult, our app is the solution for you! Our service comes at no cost for eligible users in the United States because we are funded by the FCC's Telecommunications Relay Services Fund. Spanish call captioning is also available through Automatic Speech Recognition (ASR).

Speak using your own voice and see captions of what the other party on the call is saying - it’s simple! Make and receive phone calls right from InnoCaption to keep all of your communication in one place. We also provide contact syncing, so you can easily access all of your contacts within the InnoCaption app.

Our technology lets you choose between live captioning by live stenographers or best-in-class automated speech recognition (ASR) software. You can switch caption modes at any time – even during your call! Communicate with ease, knowing the speed and accuracy of our captioning service ensures you are able to keep up with your phone conversations.

Use our captioning feature with your devices. The InnoCaption app is designed to be fully compatible with your mobile phone and tablet. In addition, our DeskView feature allows you to mirror your phone or tablet’s captions onto a computer screen or to make direct outbound calls from the computer – simply log in to our website from your computer’s web browser to access this feature.

The InnoCaption team has developed a full set of features to meet our users’ accessibility needs:

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.

Best App ever with no monthly fees!

I used to need someone else to make phone calls for me. I am hard of hearing and it is progressive. On my daughters birthday, five of us went out to a restaurant. I could not hear any the conversations. I could read lips but sentences and content were indecipherable. I was isolated the whole nite - smiling when everyone else was amd trying to nod when it seemed fitting.
INNOCAPTION has amazingly opened the door to the hearing world! I used you avoid using the phone, and now I am so empowered that I enjoy even talking to Medicare! You can select a live operator or a technology driven computer program. InnoCaption has enabled me to read exactly what’s being said with 99% accuracy.
No more asking my husband or family member to help me use the telephone. It’s not a welcome request to ask someone to call the DMV or your insurance company for you. Now I can do it myself with crystal clear accuracy.
The I ocaption features were well thought out and leave you with more than a hearing person using the phone would. For example, you can retain a copy of a conversation. That helps you with recording old phone numbers, remembering dates and ID numbers, and remembering names.
For anyone who struggles with hearing loss and subsequently using the phone, get this app. You will wonder how do you survived without it I give it 100+ percent satisfaction.

Great App

I never leave reviews, but InnoCaption has been such a game changer for me, I felt compelled to do so. This is the third caption app I have tried and it has been so much better than the others. It gives you the option of using an individual to transcribe or automated assistance. The option of a human to transcribe is supposedly more accurate and the automated option is faster. I started using it with a human transcriber and then switched to the automated option. I found both to be accurate. The automated is very accurate and the only time I have any real problems is with numbers. It can get a bit confused with phone numbers and such but it is usually so fast and accurate that it is the only option I have ever used and was able to have a normal conversation without asking people to hold on while I waited for the captions. It is the first time in 20 years that I have not dreaded making a phone call. Also, the voice mail is so much easier than my last app. My last app required using a tree menu. Push 1 for this, 2 for that, etc. Transcribers have a hard time with those trees. InnoCaption lists the calls and you just pick the one you want to hear. No need to push a bunch of options trying to find the call you want. This has been a GREAT APP for me. I hope they keep it up. I would really hate to lose it.

Love this app!

I had gotten a different TTY home phone and app before this one. When I was ready to start using it, the home phone couldn’t be connected to WiFi so I found its app. I worked many hours daily for around a week, each time I thought it was set up, discovered new issues not to be found in the tutorial.
Now THIS app?! Beautiful! It was super easy to set up plus instead of having to call customer support for any issues needing addressed, waiting for long time, you can get on a chat with them immediately. Customer service is excellent, I found this app accidentally when I found I had to use Zoom for a video appointment and was searching for help because I didn’t have anyone to come over to help me understand the doctor. That’s when I found out that this app not only works beautifully with iPhone and iPad, it has a desktop version to enable us to use closed captioning when in a Zoom appointment. I haven’t got to use this with Zoom yet but I foresee no problems with using the desktop version of this with it. I was just so happy after being able to make a few phone calls and also receiving phone calls on this after having my iPhone number forwarded to ring here, I want everyone to know this is by far, the most amazing app for the deaf! ♥️
