  I did a quick look into that and it doesn't seem it's a question we presently have a clear answer to, however, there is this:  I obviously need to look at the books, but if it requires a song to activate and Avi doesn't know it, then she can't use it; if it is what the questioner thinks it is then it requires an Ogier song and she can't possibly use it, but is still able to identify it.  was the Talisman tuned to Ogier song? Because there's a very clear Old Aiel singing tradition. And they all sing in battle.
