Good post with a lot of much needed discussions regarding the future of payments and braille literacy. Digital era has brought lots of advancements in everyone's life including the blind people. With the current technology, speech-to-text and text-to-speech voice recognition software has been playing an important role in the life of blind people.

As of now, I believe development in inbuilt text-to-speech software in bitcoin wallets would be really helpful for the blind people to take a note on the mnemonics. For instance, consider the initial phase of creation of wallet from a blind person perspective :

[1] Someone would help them in installing a bitcoin wallet app which has inbuild text-to-speech and vice versa. When they enter the app, it grants them 12 word mnemonic which can be written down in their braille notebook.

[2] While sending bitcoins to another person for payment, the receiver would display the QR code and would help the person to scan the code. Upon scanning, the app should get a confirmation from the blind person voice for sending the payment. May be the same voice should be used to send payments? Kind of this works in real time!

[3] While receiving payments, the app should again use speech-text model to use the blind person speech to provide QR code. Once the sender sends the money, the app should intimate the money received through an automated bot voice.

For these to happen in the upcoming years, we need to invest more and more time on developing rather than speculating. Crypto market on the whole is flawed IMO 99% is here for becoming rich and not for the revolution!
