The new feature uses Siri to automatically read incoming messages when you listen to music or a podcast with some compatible Apple wireless earphones or headphones to turn it on and control how often Siri reads your messages.
There are some requirements
For Siri to read your messages, iOS 13.2 or iPadOS 13.2 must be installed on your iPhone or iPad. Of course you will also need one of the following AirPods or Beats headphones:
Another important note: your iPhone or iPad must be locked with the screen off so that Siri can read your messages.
Turn on, adjust settings
After I upgraded my iPhone to iOS 13.2, the feature was already enabled, but it does not hurt to make sure this is the case, and adjust the settings if you want , Open the Settings app and go to Notifications > Announcing News with Siri .
At the top of the screen is a button to enable the feature and a section to show supported apps. At the moment it is limited to news. There is also an option to let Siri send you a message after dictating it, without first reading it, to confirm that this is what you want to send. I'll skip it because Siri is known to misunderstand me, especially in noisy environments.
If you tap News you can choose which messages Siri should read. Current options include messages from Favorites, Latest, Contacts or all.
Reply to a Message
When you receive a new message and Siri reads it to you, as soon as she stops talking you can say "Answers" followed by what the message should say. Once you're done, Siri will read the message and confirm that you want to send it, or simply send it, depending on your settings.
I made a few attempts to figure out exactly when to say "answers" and how the whole feature worked, but now that I get the hang of it, I can imagine that I use it quite often ,
Announcing News with Siri is just. Between the the improved and the ability to share there's a lot to it to like .
