Vietnamese → French
French uses 36 sounds. You already own 20 of them from Vietnamese. The other 16 are the work — and 14 of those are the dangerous kind: close enough to something you already say that you will substitute them without hearing yourself do it.
The silent swaps
Your mouth has something close enough to reach for. These survive for years precisely because they sound right to you — the fix is hearing the difference first, not trying harder.
the move: close, but not identical
French: eight · written "u+vowel"
Say /y/ and glide into the next vowel. nuit, lui, pluie.
Your /w/ is the one in sao (star; why).
the move: close, but not identical
French: good · written "on", "om"
Your /ɔ/ is the one in cho (to give; for).
the move: alveolar → postalveolar
French: cat · written "ch"
Your /s/ is the one in xin (to ask for; please).
the move: alveolar → postalveolar
French: day · written "j", "g (e,i)", "ge (a,o)"
Your /z/ is the one in dạ (yes (polite)).
the move: close, but not identical
French: good · written "b"
Your /ɓ/ is the one in ba (three; father).
the move: close, but not identical
French: two · written "d"
Your /ɗ/ is the one in đi (to go).
the move: rounded
French: you · written "u", "û"
Round your lips for /u/, say /i/. NOT English 'oo'.
Your /i/ is the one in đi (to go).
the move: rounded
French: little · written "eu", "œu (open syllable)"
Your /e/ is the one in đêm (night).
the move: rounded
French: fear · written "eu", "œu (closed syllable)"
Your /ɛ/ is the one in mẹ (mother).
the move: close, but not identical
French: bread · written "in", "im", "ain", "ein"
Your /ɛ/ is the one in mẹ (mother).
the move: rounded
French: brown · written "un", "um"
Parisians merge it into /ɛ̃/: brun = brin.
Your /ɛ/ is the one in mẹ (mother).
the move: voiced
French: station · written "g (a,o,u)", "gu (e,i)"
Your /k/ is the one in cá (fish).
the move: velar → uvular
French: street · written "r", "rr"
Uvular — at the back, like a light gargle. Never rolled at the tip.
Your /ɣ/ is the one in gà (chicken).
Words you may say identically
Two or more French sounds landing on one sound of yours. Until the ear separates them, the mouth cannot — which is what the ear trainer is for.
Genuinely new
Nothing in Vietnamese sits close to these. They sound foreign in your mouth — which is the good news: you can hear that you are not saying them yet.
Rhythm and pitch
The layer spelling never records, and the one that makes a correct sentence still sound foreign.
| Vietnamese | French | |
|---|---|---|
| Rhythm | Syllable-timed, one tone per syllable | Syllable-timed |
| Stress | No lexical stress. Every syllable carries its own tone and its own full vowel, and none is reduced. What sounds like stress to an English ear is a syllable holding its tone longer or louder for emphasis, and grammatical words (đã, sẽ, được) being said lighter and faster than content words. | This is the one that surprises everyone: French words have NO fixed stress. Prominence lands on the last syllable of the rhythmic GROUP, not of the word — so the same word is stressed differently depending on where it sits. 'Un chocolat' stresses -lat; 'un chocolat chaud' moves it to chaud and the word chocolat loses it entirely. There are no French minimal pairs by stress, because there is nothing to contrast. |
| Pitch | lexical tone — pitch changes the word | Intonation only, at the level of the phrase. A yes/no question can be marked by a final rise alone (Tu viens ?), which is why the rise matters more in French than the est-ce que you were taught. |
What you have that French doesn't
15 sounds with no job in French. They are not mistakes — but they are where an accent leaks in, because a sound you own is easy to use when a hard one is due.
The honest caveat
This is a prediction from the shape of two sound systems, not a recording of you. It says what your inventory makes likely — it cannot know that your Vietnamese has a regional variety that already owns one of these, or that you learned French from someone whose accent you copied. A teacher listening to you beats it. Use it to know what to listen for.
