The live translate feature in phone calls should listen to what is said, convert it into text, translate the text, then read it out using a robot voice. It might be able to just show you a text translation though I've yet to actually try it out
That's the problem, that the robot's voice doesn't work correctly, translates inaccurately. And you can't turn it off, and you can't make out what you're saying with the image. If you're eating very well, you can only leave text only.
