I am not blind myself (yet) … But how do blind people feel about morse code for reading text (or writing it)? Is it a workable solution, or is neural-network based text-to-speech and speech to text preferred? Drawbacks of morsecode include that it takes long to learn and to master.
But these kind of signals can be even understood by blind or deaf people.
I would think you would have to, and I know for a fact that I could not do it.
