On steam I can use the Esc on my keyboard to toggle text chat. I don't have a Xbox or play station. But I thought you could connect a keyboard to one of those. ? Maybe it would work the same ?

Also, I think there was a speech to text feature.

Sorry it's been a while since I played but I'm almost positive that when I used the mic in game, it converted it into text.

I don't know if any of that helps you. Plus this is a few week old post.
