I would love the opposite: text messages that can be go from text-to-speech. Specially useful when doing chores and those long threads some people write. Or one of those busy groups where everyone is saying something. Just hit play and let the phone read them all. (I use WhatsApp)

Or is this a feature I am unaware on phones?

I think you can ask Siri or Google Assistant to read your new messages (by accessing the phone notification contents), but I'm not aware of in-app features.

Siri can read text from apps (messages, email, etc.): "Hey Siri, read the last WhatsApp from John".

It will ask permission for access the first time you try.

Google Assistent can read out your messages, but i haven't tried out of it can read from one specific group chat.

It is.
