Strange sound in UTLH

[SwedeChildO'Mine]

If you listen very carefully to Used To Love Her (Lies version), after about 2:29 you'll here a light voice (I guess female) who says a sound which sounds something like: "sa-a"

Am I the only one to hear this?

If someone knows: What's she saying? Why is that sound in the song?

I think it's Axl. The song is a joke, nothing more, and this funny voice is quite great there.
