Koh-mahn ah-lay voo
Here's a breakdown:
* Comment: "Koh-mahn" - the "c" is silent, the "o" is short and pronounced like the "o" in "hot"
* allez: "ah-lay" - the "z" is pronounced like the "z" in "zebra"
* vous: "voo" - the "ou" sounds like the "oo" in "moon"
Important Note: The "s" in "vous" is silent in this phrase.
When you pronounce it, make sure to connect the words smoothly and use a rising intonation at the end, as if asking a question.
