How to use the text-to-speech feature on iPhone
In the iOS 17 update, the iPhone got a built-in text-to-speech feature called “Live Speech,” and it comes with a great additional feature called Personal Voice where you can create a digital copy of your personal voice to be used by the Live Speech tool when converting text to speech instead of using Virtual sounds. Instead of hearing a robotic voice when you convert text to speech, you'll hear your real voice if you set up Personal Voice, making the text-to-speech experience more realistic.
