right!   dude clearly did not read the books.
and it is most definitely Bran like tan or man or Stan or can.  
Listening to these books on audio book forces your pronunciations.  The 1st three of these books are narrated by
 Roy Dotrice
Roy is also playing 
Grand Maester Pycelle in the series.  

 and that's how he says it.  BEST NARRATOR  EVAR.
Here is a sample of him doing the voices of Tyrion and Braun as he narrates from Tyrion's perspective... as Tyrion tells his hired Sell Sword/Steward, Braun of the way he met his first wife.  This is one guy doing the narrating and all of the characters in these books, mind.  He's so effortless as he slips from one voice to the  other, and then to the 'narrator' voice that you forget all about him as a narrator.  You're seeing the character in your mind.  He acts the dialogue, too.  If you have 6 minutes, listen to this.  Now in these books, he does use the same gruff voice he uses for Braun when he's doing Sandor Clegane and several other tough guys.  But then, Tyrion and Varys and Sam Tarley and Doloros Ed, and I don't know how many other distinct voices are unique and quite complete.
The 4th book is done by one 
John Lee.  (click that link and hit the little green arrow under the picture of the book to hear him)  Not a bad narrator... a bit slow and quite smitten with his own voice... it's a good one, I suppose, but not so great following Roy.
