I translated Japanese into English with translation software.
I took a closer look at your puppet.
1) The jaw moves up and down greatly
→ The crown mark on the BG layer has been turned off.
→ Changed lip sync jaw movement from 100% to 21%
2) The mouth is displayed twice
→ Switched Mouse layer and Singles layer with swap set.
3) Your Mouse layer on keyboard 1
Keyboard 2 switches to Your Singles layer.
However, Your Singles layer does not have a sound-switching mouth change layer, so it does not respond to sound.
