Which gadget to buy for the blind?

Question

Mobile devices

Hello.
I would like to give a gadget for a blind person. A person confidently spits on a computer, using voiced systems, and wants to buy something interesting.
I googled the topic of smartphones for the blind for a long time. I heard that now there are developments for android: there is voice acting for gestures and other actions that even the touch screen is not a problem.
But googling didn't turn up anything. Maybe someone is familiar with this topic and can tell me?
The option to buy a phone and put voice acting on it is not very good for me. I would like a finished product.
