Most of the character voices were taken directly from the game, but some were tones already in GarageBand (yes that's what i use im cheap) that sounded like the characters, to me at least.
Also don't get triggered if that's not how you headcanon Frisk's voice, that's just a sound I thought would be very sweet for some things but mildly creepy for others, which I personally think represents the whole Pacifist vs. Genocide thing very well.
