Now, I am far from an expert in reading these phonetic writing systems, but I am pretty sure at least two of those do not contain any 'l' sound. And when playing the audio version on all except the last link I am not hearing an 'l' sound either. Sooo, I am assuming these pronunciations are somehow localized, yet I am unable to figure out who is saying it which way?
