My hearing clarity has gone. If I did not have the close caption I would be lost. Thank you so much

I need help

The time it takes to reach me after the call is made lacks a lot in my opinion. I had my wife call me and i waited and waited to the point i called her back to see if she called me immediately. Of course was her response. Nothing. I think this may work if there’s assistance but I’m having trouble locating it so here I am frustrated.

How much does InnoCaption cost?

InnoCaption is available at no cost to eligible users in the United States through funding from the FCC’s Telecommunications Relay Services (TRS) Fund. This means individuals with hearing loss can use the service without direct charges.

What are the key features of InnoCaption?

Key features include live captioning for all calls, the ability to switch between stenographer and ASR captions, text-to-speech calling with AI refinement and shortcuts, AI-powered transcript summaries, saved call transcripts, and a spam call filter. It also allows users to keep their existing phone number.

Who is eligible to use InnoCaption?

InnoCaption is available at no cost to eligible users in the United States who have hearing loss. Federal law requires users to be registered individuals with hearing loss to use internet protocol (IP) captioned telephones with captions turned on.

Can I use my own phone number with InnoCaption?

Yes, InnoCaption utilizes patented One Number technology that allows you to keep your existing phone number. You can use the app like your regular phone dialer without needing to make calls through a traditional 711 relay service.
