Voice type for Sprunki’s

So I’m making a Sprunki “College AU” and since Sprunki is a music game everyone is in a choir class, so I was wondering which type of voice do you think the characters would have? Also Funbot & Mr. Fun Computer don’t count since they’re both robots.

Voice types in case you don’t know:

Soprano(Highest female)
Alto(Lowest female)
Mezzo-Soprano(mid-range female)
Tenor(Highest male)
Baritone(Mid-range male)
Bass(Lowest male)
