Every time i adjust the volume a female voice announces the new sound level.
Apple TV wouldn’t do that, afaik. Please see if your TV has a settings that may announce volume changes using speech.
It also reads the type of page.
The Apple TV box has a VoiceOver function that is intended to help user interface navigation (the menus) to the visually impaired. You may have activated that accidentally.
