Is a headset microphone interfering Character Animator?

A headset microphone is a great way to record audio for automatic lip sync assuming the microphone is high quality. Depending on the design of the headset, it might interfere a little bit with the camera's ability to track the mouth, but that is currently only used to:

* Trigger a smile/surprised expression from the camera (just as easily done with the keyboard)
* Resize the mouth based on your mouth openness (this is quite uncommon for puppets)
