Suggest you run a thorough deep offline scan with Windows Security. Might not hurt to install Malwarebytes and run a secondary scan. It appears you may have a virus or similar on your system.
Have you recently installed a program, gone to an unfamiliar site with your browser, or even downloaded something?
It's possible that a feature called Narrator has been turned on accidentally. Narrator is a screen reader that reads text and other elements on the screen aloud. To turn off Narrator, you can press the Windows key + Enter. If that doesn't work, you can try going to Settings > Ease of Access > Narrator and turning it off from there.
