Hand-free chess and other suggestions

Hello, a couple of years ago I came up with the thought that it will be great to have speech recognition so you make moves while doing other stuff, Idk if it would be too hard too implement.
You could also have a tool that reads the moves out loud so people (pro-players) can play without having to be looking to the chessboard at all.
I think it would be also interesting to have a graph in your profile that instead of plotting your rating day to day on the x-axis does it game to game. That way you have a smoother line that will ignore periods of inactivity.
I'm not sure about this last idea though
What do you think?

Your first suggestion might collide with some parts of lichess' anti cheat recognition :(
I second your second idea. :)

I don't see why. Don't they just analyse the game to see if the player is using computer assistance?

They are using every information, they can get. Accounts have been marked, because the players had connected a DGT board and a software, that translated their moves on the board into simulated mouse-clicks.
