Person who can't speak wishes to use tts on a phone call

Hi, I write free software for persons with multiple disabilities, please see http://www.bapsi.org/vibrations-series-of-products-for-deafblind

A friend who does not speak but needs to talk on the phone for her work asked me how that might be solved. We could use two phones, with one of them running an app such as dbtype that uses tts, and the other making the call. It would, of course, be much better, if it could be done with a single phone. Any suggestions?

warmly,
Arun

Have you tried Google’s Accessibility Suite ?
It has a feature called RTT which allows for text typing during calls

Thank you for that, Tim.

My friend wants to send voice across the phone, even though she cannot herself speak. I do not see how RTT solves that problem.

She can text while the other party speaks by using WhatsApp, but she does need to send voice across the phone line. For instance, she would like to communicate with people who only have a land line, where only analog audio works.

It is surprising that there is nothing in the accessibility suite that handles this, plenty of options the other way.

I have done a little test with an example app, setup with a few stock phrases. Seems to work with phone on speaker and volume for speech turned right up.

  1. Initiate phone call
  2. Press Home button, or square button, to open text to speech app
  3. Type text into app and press play
  4. Receiving phone should hear output - if a bit quiet - I think when on a phone call it quietens other audio sources, this might be adjustable somewhere.

It may be possible to do something similar with Talkback…

Thanks again, Tim. We would like better quality audio than this solution offers. If I could feed the audio out of the phone to the audio in, that would be great. I could use a phone patch, which would be a hardware solution, but surely there should be a way of doing this in software, so that my friend does not need to carry another clunky device together with her Android phone?
