.. Kansai dialect ... 

I dunno if this is helpful or not but if that dialect is supposed to be the backwoods/country version of Japan then the best way to translate that to English would be to slur certain words that end with vowels and shorten long words. At least in America that is. There is different version of country where it gets harder and harder to understand until it gets to the near incomprehensible.
