Whenever you receive a new message with Announce Messages with Siri, the digital assistant will politely interrupt whatever you happen to be doing when listening to AirPods in order to read your incoming text or texts. It’s a great feature, but it’s not for everyone. Here’s how to manage it.
On iOS, head to Settings > Siri & Search > Announce Messages. To disable the feature entirely, tap the toggle next to “Announce Messages with Siri.” You can also tap the toggle next to any app in the list to disable the feature for that app only. If you tap “Messages,” not only will you find this toggle, but you can also choose whether Siri will announce messages from Favorites, Recents, Contacts, or Everyone.
There’s also Reply without Confirmation; disabled by default, this setting lets Siri send your responses without reading it back to your first. It can be convenient, but also dangerous; you won’t know if the assistant misheard you before sending off your reply.
