It’s in settings, accessibility, under speech click personal voice and follow the prompts. Of course that’s tough in itself as you have to say phrases to the phone but you can just keep hitting retry if you struggle on some. Once all finished triple press the power button and a box will pop up you can type it and hit send. People have said typing out full words sounds emotionless so they can tell it’s not really me but one letter they have no clue because it’s using my actual voice to speak. Love it! Just need an in person one attached to my mouth 😂
