I know how to make a Baldi voice! If there are scripts for the voice lines, I'll surely make the audio!
EDIT: Also, if you're able to, you can send the sounds to me via a link that is quite manageable enough. Furthermore, what do you have in store for your mod of Baldi's Basics?
(tools: anim8or for baldi, baldis basics plus for items, fontsace for font and photoshop for editing!
