Huawei tablet with Android no longer works properly, a voice keeps playing?

I bought a Huawei tablet with Android around the fall of last year.

Something is wrong as of today. There's always a voice with everything

what I do, everything is always outlined in green, I can no longer use the tablet properly and can't get in anywhere, I can no longer go from one to the other

Swipe other start screen. And a voice keeps coming, what a problem that could be.

Then the lock screen can be seen, outlined in green, it says: swipe to unlock, but I can't get to my start screen at all, a voice keeps playing with something (new message, battery on… Etc.)

Simply press both volume buttons at the same time

It's just so unnecessary, but it doesn't matter if it works then it's good.
