I don't suppose I can be a lot of help but someone else might be if you provide more information.
Are you watching terrestrial TV off air?
Or satellite? Or cable?
Are you streaming an internet service on your PC? Or your TV set?
Does this mysterious voice over occur every time you watch something or only on certain channels? It sounds, at a guess, as if you have somehow turned on a narration facility, designed for the visually impaired and, if so, you should be able to tun it off by going to the Settings menu on your TV or other device or, if it's only one service that's affected, take a look at your Settings/Preferences for that service.
