I couple issues I noticed:
1. Between syllables or words, my character's mouth flaps open and shut wildly, because of the fluctuating mic level during that.
2. Character opens mouth for tapping noises or background noises.
Feature suggestions to solve these issues:
1. Character's mouth stays open for a couple frames after the mic has fallen silent. (it's an optional feature, a slider for how long to stay open afterward)
2. Include a noise cancellation feature like Discord has (they use Krisp) or like OBS has.
