Speak with an almost stereotypical French accent. If you're going to impersonate an official actor, go for Rob Paulsen in Sonic SatAM.

Cowardly, easily spooked member of the Freedom Fighters. Antoine is a dutiful soldier and valiant fighter, something he has achieved despite youthful fears largely through Bunnie's example and help. While he still has the tendency to be anxious about things, he is quick to put it aside when needed. Antoine has envied Sonic's superior abilities over the years, and puts on bravado not unlike the Hedgehog's in battle while enjoying any opportunity to be amused as Sonic's expense. 

Speaking both French and English, he struggles occasionally with the latter, particularly during intense situations, and will sometimes use an incorrect word. Apart from his wife Bunnie and his efforts to defeat the evils that threaten Mobius, Antoine's greatest passion seems to be cooking.
