How do you say Cannes in french?

The French pronunciation of "Cannes" is very close to how it's spelled in English. It's pronounced:

"Kan"

* The "C" is pronounced like the "k" in "kick"

* The "s" is silent

* The "es" at the end is pronounced like the "z" in "zebra"

So, it's pronounced as a single syllable, with the emphasis on the first sound.
