Voice Model Sounding so robotic on W-Okada

[jaunty mulch]

I tried the Lucifer from Hazbin Model and it sounds so robotic. How can I solve this?

Maybe you have set the chunks too high

Your PC isn't powerful enough

Or the model you're using is straight up poorly made

Also, depending if it's an male or female model, you should try playing around with tune settings
