Use Siri dictation on Apple TV
Whenever you see an onscreen keyboard — such as when searching in a third-party app or when entering a username or password — you can speak the text instead of using the onscreen keyboard.
Speak text instead of typing it
With a text entry field highlighted on screen, press and hold the Siri button on the Siri Remote and say whatever you want to enter in the text field.
Speak usernames and passwords
If a text field tells you to spell out characters instead of speaking words, press and hold the Siri button on the Siri Remote, then say the letters, numbers and symbols you want to enter.
Say “uppercase” to enter an uppercase letter.
Siri recognises many domain names such as icloud.com, so they don’t need to be spelled out.
You can use phonetic or military alphabet pronunciations, such as alpha, bravo, charlie, delta for A, B, C, D and so on.
You can say “Clear” to delete the characters you just entered.
Clear applies only to characters spoken during the current Siri entry. For example, if you say “A, B, C” then release the Siri button, then press it again and say “1, 2, 3, clear” the numbers will be deleted but the letters will remain.
Note: Dictation sends information, such as voice input and location, to Apple to process requests. Voice input from spelling dictation of usernames and passwords isn’t sent.
Turn dictation on or off
Open Settings on Apple TV.
Go to General > Dictation, then turn dictation on or off.
