La voix

une voix (pronounced voo-ah) = a voice. It also means (very appropriately) a vote or ballot.

For example:

• ça m'a laissé sans voix = it left me speechless
• il a gagné avec 60% des voix = he won with 60% of the votes
• casser la voix = to break/lose one's voice, as in Patrick Bruel's famous song from the late 80's. If you're not familiar with the carreer of this actor/singer and (yes) World Champion of Poker in 1998, start here.
