It's been a while now but once out of curiousity I tested the text to speech functionality (with my eyes closed) on an iPhone and another device (a laptop maybe?), and found iOS to be more advanced but still lacking. I don't know much about this but it's nice to see improvements. GrapheneOS seems to be a high value project in terms of dollars-to-output.

Excellent to see progress here

Would be more interested in speech to text.

Awesome! Now how do we use this? I tried selecting text and seeing if there was a "Speak" menu item but there doesn't seem to be.
