Change the language or region format on Apple TV
The first time you set up Apple TV, you choose which display language and region format to use. You can change this later in Settings.
Add a language
You can add multiple languages so that you can change the primary language or switch between different languages when the keyboard appears on screen.
Open Settings
on Apple TV.Go to General > Apple TV Languages, then select Add Language.
Select a language from the list, then confirm whether it will be the primary language or an additional language.
Languages you add appear in preferred language order in the list. This means apps will use the first language listed and keyboards will appear in your preferred language order.
Note: Siri and dictation may or may not be available, depending on the language you select. For more information, see the Apple Support article Use Siri on your Apple TV.
When you use the onscreen keyboard, select the Language button 
to switch to the next language in your list of languages.
To change the order or delete a language, see the task below.
