What do you call a person who can speak without moving his lips?

This is a bit of a trick question! There's no specific word for someone who can speak without moving their lips.

Here's why:

* It's impossible to speak without moving your lips. Speech requires the coordination of many muscles, including those in the lips, tongue, and jaw.

* There are people who can speak with very minimal lip movement. This might be due to a medical condition or a learned skill. But they are still using their lips to some degree.

It's important to remember that language and communication are complex, and there are many ways people can express themselves.
