Just after the woman says "Can you take us to the 2nd letter" there is what sounds like a choir or singing of some sort.

Singing

Again during the same ouija board session. Just after woman says "Can you take it back to the star" and just before she starts talking again, you can hear a little boys voice say Noooo.

Kid Nooo

Long one this one but it puts things in to context. Right towards the end you can hear a girl say what to me seems like Bianca or something like that.
