There’s now support for onscreen text entry via dictation in countries where Siri is available. When updating to tvOS 9.2 beta 3, users will be prompted to enable or disable dictation. With dictation, Apple TV users can dictate text and spell user names and passwords rather than typing them.

The first time I heard speculation of spelling out usernames and passwords on the Apple TV with dictation was in episode 135 of The Talk Show. John Gruber and Adam Lisagor spent a great deal of the episode discussing the new Apple TV and I think it’s worth revisiting now that we know all (or most) of the features that will be added with tvOS 9.2.
