How to Pronounce French 'oi': The Sound in 'Moi', 'Trois', and 'Croissant'
The French 'oi' sound appears in hundreds of everyday words. Learn exactly how to produce it, common mistakes English speakers make, and how your accent affects the approach.
How to Pronounce French "oi"
The "oi" combination appears in some of the most common French words: moi (me), trois (three), croissant, boire (to drink), soir (evening), and voiture (car). Getting this sound right makes an immediate difference in your French.
What Does "oi" Actually Sound Like?
The French "oi" is pronounced /wa/ — like "wah." It's not "oy" as in "boy," and it's not "oh-ee." It's a quick glide from a "w" sound into an open "ah" vowel.
Say it now: Take the English word "wah" (as in "wah-wah pedal"). That's almost exactly the French "oi." Now put it in context: moi = "mwah," trois = "trwah," soir = "swahr."
The Most Common Mistake
English speakers almost always pronounce "oi" as "oy" — like the "oi" in "oil" or "coin." This is completely wrong for French.
| Wrong (English reading) | Correct (French) |
|---|---|
| "moy" | "mwah" |
| "troy" | "trwah" |
| "kwah-SAHNT" | "kwah-SⱭ̃" |
The English "oi/oy" is a diphthong that starts with an "oh" sound and glides to "ee." The French "oi" starts with a "w" and opens into "ah." They're completely different movements.
How Your Accent Affects This Sound
American speakers: You tend to produce a strong diphthong for "oi" words. The challenge is replacing the "oy" muscle memory with "wa." Practice by saying "wah" before adding any consonants around it.
British speakers: Your "oi" in words like "choice" is similar to the American version, but your softer consonants mean less interference when transitioning to the French "wa."
Australian speakers: The Australian "oi" (as in "oi, mate!") is actually closer to a strong "oy" — you'll need the same "wah" replacement as American speakers.
Irish speakers: Some Irish English dialects produce "oi" sounds that are closer to the French version. Listen to your natural "oi" and see if the transition to "wa" feels shorter.

Frequently Asked Questions
Is French 'oi' the same as English 'oi'?
No. French "oi" is pronounced /wa/ (like "wah"), while English "oi" is pronounced /ɔɪ/ (like "oy"). They look identical on paper but represent completely different sounds. French "moi" is "mwah," not "moy."
Why is 'oi' written as 'oi' if it sounds like 'wa'?
This is a historical spelling. In Old French, "oi" was actually pronounced closer to "oy." Over centuries, the pronunciation shifted to /we/ and then to modern /wa/, but the spelling was preserved. French spelling often preserves historical pronunciation.
How do I pronounce 'croissant' correctly?
The French pronunciation is /kʁwa.sɑ̃/ — approximately "kwah-SAHNH" with a nasal final vowel and a throat R at the start. The "oi" is "wa," not "oy" or "oh."
Are there exceptions to the 'oi' = 'wa' rule?
In standard French, "oi" is always /wa/. The only variation is regional — in some Canadian French dialects, "oi" can sound closer to /we/ in certain words. In standard European French, /wa/ is consistent.
