Well, it could just be that she sees it as a logical stepping stone for other acting work, or a way to build craft in a direction that is both versatile and novel to her.
True?
I have been occasionally surprised at what seems to provide uncharacteristically-- sometimes even disproportionately so-- motivation to DD.
Often it comes down to "I was thinking that it would be ____, and it turns out that I was thinking that because of a lack of life experience" but most of those things are things that DD doesn't seem to readily articulate, even when we try to understand suspiciously enthusiastic behavior.
Well, it sounds like you know what I mean by that last statement.
I've found that mostly it is the case that DD is making a VERY particular assumption about what is in it for her-- and it really would be best if she'd share her vision with us, because honestly, sometimes she has no idea what she is getting herself into.
I guess I'm saying that without actually being in her head, you don't really know whether its the prospect of a step into the adult (paying) world, the notion of working with professional actors and directors and producers, or something else entirely (I have a dream of wearing a monkey suit on national television).
No way to know.
My DD did a bit of regional voice-work at 6-9 yo, and I did too at ages 3-5 because of connections in commercial radio at the time. It was low-pressure and fun. DD especially enjoyed the technical toys that the audio engineers had. She loved that part of things, and she and they often had fun tweaking her voice and digitally cut-and-pasting things. It was like playing with photoshop but in an auditory landscape.
I do hope that she has fun and is happy doing it! DD decided on her own at 10 that she didn't want to do it anymore, and hasn't since. It was evidently a short-lived phase for her, but she doesn't really have a fine/performing arts passion.
