late to this thread....

btw, I always heard keh'-bek-wah

I know y'all figgered it out but I just wanted to add that I recently learned that in pronouncing French words, there's a rule you can follow with regard to whether you pronounce the last letter or not. Vowels, you don't - but if it's a consonant, do you? You do - if it's one of the consonants from the word "careful".

Hence the difference in pronunciation of Quebeçois (final letter "s" and therefore not pronounced) and Quebeçoise - the latter's final letter is "e" (not pronounced, but the "s" now is because it is no longer the final letter - if that makes any sense!).
