I think they're doing something with sound/voice that's bigger than just Agatha finding people sexy. I find it a bit hard to believe a non-spark can imitate Spark subsonics. That just feels off. But there's something going on with what voices do.
There's obviously Lu/Agatha's ability to command the wasps. There's Agatha's ability to heterodyne, which requires hearing as well as vocal production: she has to hear what she's aiming for to hit it, that's why deaf and tone-deaf people can only sing a tune with tech-help to allow them to see when they're frequency-matching. There's the hint that Tarvek can hear very specifically, and thus possibly reproduce Agatha's heterodyning. There's the fact that he's the one who figures out how to reproduce Lu/Agatha's voice, and that he manages to improve it beyond his own expectations for Anevka.
It will be very interesting to see what they do with that.
