Standard French and Cajun doesnt seem to similar to me. I have the Rev Daigle Self Taught book, he does have some good pronounciation guides in it.
On top of it all, the pronounciations change a little area to area, though Cajun French does share some common rules, for example in "tre" or "dre" endings, the "re" is not pronounced unless followed by a vowel or silent consonant. And Cajun French seems to eliminate as many vowels as possible in pronounciating, such as "je te.." becomes "j't'..".
