Can I make my puppet's arm move (trigger) automatically when I talk?

Hello,

I'm new to character animator. I drew my own puppet with mouth movements and arm movements so my character can raise his arm and talk. I was able to figure out the swap set to make it talk using the how to videos. My question is, is there a way to make his arm trigger (switch to a different pose) automatically via audio or when it recognizes sound? I don't want to us the keyboard for this trigger. I tried the cycle layers, layer picker (using the audio input option) and leader/follower behaviors but couldn't get any of them to work. Am I missing something? Is this possible because I've seen a puppet on a youtube channel with this feature. Please let me know if this is even possible. Note: Also I do not have a camera hooked up at this time. Thanks much
