It works on phone calls and FaceTime calls, and even face-to-face conversations. You can find it in Settings -> Accessibility -> Live Speech. Here you can even choose voices and add favorite phrases that you can choose when Live Speech is running.
Personal voice
Personal voice is only available in English so far, but it's definitely a remarkable feature. This feature turns your own voice into a digital voice that you can use in Live Speech. This is great if you are at risk of losing your voice or just want a break from speaking out loud. Just train Personal Voice with 150 phrases and iPhone will create and securely store your unique voice. Then type text and use Personal Voice through the speaker or in FaceTime, Phone, and other communication apps. You can find it in Settings -> Accessibility -> Personal Voice.
Siri speaking speed
Most of you don't have a problem with Siri's speaking speed, but if it's too fast or too slow for you, you can adjust Siri's speaking speed to your preference. Go to Settings -> Accessibility -> Siri -> Reading speed and set the speed that suits you best.
Pause animations
If you don't like the visual bombardment of GIFs in Safari or News, you can turn this feature off so that animated images don't play automatically. Instead, you can tap the image to play it as needed. Go to Settings -> Accessibility -> Motion -> Autoplay animated images and turn it off.
