The latest rumors are that the new Apple TV will have a built-in microphone, while the upgraded remote will get a speaker. The mic would let users control the set-top box using Siri without having to speak into the remote or a connected HomePod device. That could also let the Apple TV serve as a simple smart home hub - controlling thermostats and locking doors - without the need to hunt for the remote.
If you happen to misplace the remote, the new integrated speaker should make it easier to track down.
