What software is this? How to pronounce this expression?

This is not software. This is Animoji, a mobile emoji package that comes with iPhone X. It can accurately capture your facial movements with the front camera and reflect them on the emoji expression in real time. At present, Animoji provides 12 classic and interesting emoji expressions, such as cats, dogs, aliens and poop. Although Animoji is put in the native information App in the form of iMessage App by default, you can also save it and send it to your friends via WeChat. This was an important selling point when it was released at that time. Apple models after iPhone X, such as iPhone Xs and iPhone Xs MAX, also have this function. If you want to experience Animoji, you need to complete these preparations: buy an iPhone X, open iMessage, select contacts, and then select the "App Store" logo next to the input box. Next, you will have a good time!

After choosing your favorite expression, you can see that the expression at the bottom of the screen changes with your expression by pointing your face at the mobile phone (the side face may not be recognized …).
