Is it okay to specify vocal types when describing a character's voice?


I’m back again with a new question.

I’m stuck on how to describe a character’s voice (the placement is near the end of the book, but I find it crucial to cue the readers into who is speaking when this said character speaks outside the setting, and this is how I want to do it.)

(To further explain: the narrator is inside a cabin, and the character I want to describe is outside the cabin.)

But to the question in the title: is it okay to specify vocal types when describing a character’s voice? By that, I mean, can I use the words coloratura soprano, soprano, mezzo-soprano, alto, contralto, countertenor, tenor, baritone, and bass?

Bass and baritone are common enough, and I bet people would understand if you used soprano. Alto and tenor would probably require a bit of musical knowledge, and the rest likely require vocal knowledge specifically.
