I think It would be a good idea to have emotions/expressions triggered to audio input, I use Character Animator for content creation (twitch/youtube) but have camera turned off, since I move around a lot, and I think it would be a good idea/useful for the character to react with facial emotions such as when I scream from being scared to show a scared face or when I laugh show joy or happy or laughing, or when I yell in anger/frustration, to show anger emotion.
