dependency of meter on dialect

[Magpie]

I have also come across this problem, although I didn't realise that it was a problem until I started writing Haiku that strictly adhered to the correct syllable count. I am Geordie and found that a lot of words pronounced in my dialect have an extra syllable in them; such as "film" which Geordie's pronounce as "filum". Apart from Haiku I haven't written any other poetry which has meter or a syllable count, but I am hoping to soon, so I will no doubt be encountering this dilemma more frequently. So thanks for the helpful advice posted here.
