The pronunciation is cam-bee-AYS.
The answer to the second question is yes.
-I conjugated the verb cambiar for you (plural) and it is cambiais. I'm not sure about the pronounciation. Would it be cam-bye-ice?
-Is Spanish like French in that if you have two vowel sounds next to each other (la assistencia) you change the first to make it more distinct?

1. Many textbooks do not use the vosotros/vosotras form, but if yours does, the Present Indicative IS cambiais. The pronunciation is more like: a = ah cam-bee-ay-ees with the stress on the "ay"
2. 2 vowels together is a dipthong. If you remember "u" (you) and "i" (I) ARE WEAK, you will understand why often they have accent marks. (caí, continúas) Otherwise you would have the sound of "cay" or "con-tin-wasss" with the stress on the "i" of the 2nd syllable.
Actually you do not CHANGE anything in a dipthong. When a Spanish word has two vowels side by side, various pronunciation issues come into play: syllable division, diphthongs, and hiatus. A dipthong is also known as a "sliding vowel." American English vowels are REALLY dipthongs: a, e, i, o, u. Say them aloud and you hear a faint "y?"a-e / e-uh / i-yuh / o-wah / eu-uh? (Please forgive trying to use English letters to represent sounds!)

Para México no usarías "cambiais" sino "cambias"
