My puppet keeps moving it's mouth even though I am not talking

Hello Adobe Community!
In Adobe Charcter Animator, the puppet keeps moving it's mouth even though my lips are not moving at all. I tried to choose several other default puppets and the result was the same. Lip Sync Viseme Detection is at default. All the other settings are pretty much default. I attach a video of the problem. Please help me solve this problem. Thank you

My computer fan is enough to activate the mouths, I wonder if it is background noise? Does the mouth still move if you turn off the microphone? If that is the case you might want to play around with your settings a bit. Okay Samurai talks about the lip sync settings in this video. Camera based muting might help (10:08 in the video)

Using a headset does a good job of filtering out extraneous background noise. You might want to give it a try. Also, the camera sometimes picks up on facial expressions (smile, surprise) and shows them when you don't intend to. You can turn that feature off if it's becoming too uncontrollable.
