Yeah that pronunciation was a bit of a shock when I first listened to the radio drama, though I had hoped it was just a mistake (like how they used the Rebel fanfare for the Imperials). But I guess it’s official? Weird.
I assume that’s where they looked when deciding on a “canon” way to say it.
But as Lucas used to say with regards to pronunciation: “Ehh, it’s a big galaxy.”
True. Leia, Han, and Obi-Wan all have two different pronunciations in the OT. Tatooine has one pronunciation in the OT and another in the PT. George pronounces gungans differently than everyone else. Even in TFA you have two people pronouncing Jakku differently in the span of about 10 seconds.
