Also optimized is the Siri callout page. Say "Hey Siri", or press and hold the lock screen button, you will no longer see the full-screen question window, instead a circular animation pops up at the bottom, and Siri's replies are also presented in the form of bubbles.
Speaking of Siri, audio information has also been enhanced in iOS 14: When you want to make the message more expressive, you can easily send audio information with Siri.
