@Elias, you sound around 19-25. Great results, I'm jealous!
@Harlee, that voice + Aussie accent = totally winning the vocal lottery, IMO, haha. 20-30, I'd say.
@DonScarletto you sound young, 11-13, but that's to be expected for pre-T. Not a bad start at all, I'd say it's in the mid-range of pre-T voices; not super squeaky, though not baritone, by any means 😉
