Do girls singing voices change during adolescence?

<p>Her speaking voice and singing voice do not sound hoarse. A few notes sound airy (she says) when she sings. These are at her upper register. Voice teacher does not seem concerned. There is also the issue of some asthma meds that she “forgot” to take for at least a month or two. Meds have been restarted, so there may have been some decreased lung capacity. In any case, I plan to take her to an ENT doc just to make sure everything is OK. There has not been excessive singing, belt singing, screaming or anything else like that.</p>
