That was a big problem when I moved from Victoria to Adelaide when I was 6.
In Victoria, they say "plant" and "castle", while in Adelaide they say "plant" and "castle". Then we moved to the ACT, and they say "plant" like they do in Victoria, and "castle" like they do in South Oz.
Nah, Shannow's right. Victorians say castle, and crow-eaters say castle. Except for me, for some reason I say it the crow-eater way. Same as mall and mall.
I think that 'mall' and 'mall' are different things though, not just different ways of saying the same thing. They probably aren't, that is just how I think of it.
People should all go around pontificating in Shakespearean style monologues. I try my best, but yea, it doth confuse the shit out of everyone.
I pronounce everything the standard BBC English way, except for words like "temporarily" which I pronounce the way Americans do. There's a syllable there, use it!
Some rules:
* "schedule" has a soft c sound after the s. I pummel anyone I hear referring to it as a "skedule"
* "harass" is pronounced the same way as a particular bass player's surname
