Turkish → Vietnamese
Vietnamese uses 35 sounds. You already own 20 of them from Turkish. The other 15 are the work — and 15 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
Vietnamese: to eat · written "ă", "a (in ay, au)"
A SHORT a. Written ă on its own, but the a of tay and sáu is this vowel too — which is why tai/tay and sao/sáu are different words.
Your /a/ is the one in anne (mother).
the move: velar → palatal
Vietnamese: house · written "nh"
Spanish ñ. Also a final: anh, bánh.
Your /ŋ/ is the one in renk (colour).
the move: close, but not identical
Vietnamese: three; father · written "b"
Implosive: the larynx drops and air is drawn in as the lips open. A plain English b is understood, but sounds foreign. New for Korean speakers too — Korean ㅂ is neither voiced nor implosive.
Your /b/ is the one in balık (fish).
the move: close, but not identical
Vietnamese: to go · written "đ"
The barred đ is the ONLY d-sound in Vietnamese; the unbarred d is /z/ (or /j/ in the south).
Your /d/ is the one in deniz (sea).
the move: aspirated
Vietnamese: to like · written "th"
th is an aspirated t — never English th. thích rhymes with English 'tick', and th is exactly Korean ㅌ against the plain t of ㄸ; a Korean speaker hears this pair without trying.
Your /t/ is the one in tuz (salt).
the move: unrounded
Vietnamese: cooked rice; a meal · written "ơ"
Say /o/ and unround the lips — the same horn, same instruction. Close to Korean ㅓ (eo), and to American 'bird' with the r taken out.
Your /o/ is the one in okul (school).
the move: unrounded
Vietnamese: to weigh; a kilo · written "â"
A SHORT ơ: cân is clipped, cơn is held. The vowel of American 'cut', or a short Korean ㅓ.
Your /o/ is the one in okul (school).
the move: close, but not identical
Vietnamese: star; why · written "o-, u- (before a vowel)", "qu-", "-o, -u (after a vowel)"
Both an on-glide (hoa, quê) and an off-glide (sao, đâu).
Your /j/ is the one in yol (road).
the move: open → open-mid
Vietnamese: mother · written "e"
Open e — French è, the e of American 'bed'. Korean ㅐ as it was before Seoul merged it into ㅔ: Vietnamese still keeps the two apart, so mẹ 'mother' and mê 'to be entranced' are different words.
Your /a/ is the one in anne (mother).
the move: close-mid → open-mid
Vietnamese: to give; for · written "o"
Open o — the vowel of 'law' for an American who keeps caught apart from cot, shorter. Korean has nothing between ㅗ and ㅓ; this sits between them.
Your /o/ is the one in okul (school).
the move: plosive → fricative
Vietnamese: no; not; zero · written "kh"
German ach, Spanish j — or Korean ㅎ in front of ㅡ (흐), which comes close. không is the word you will say most.
Your /k/ is the one in kara (land / black).
the move: plosive → fricative
Vietnamese: chicken · written "g", "gh"
A voiced fricative, like Spanish g between vowels — softer than English g. gh before e/ê/i.
Your /ɡ/ is the one in gol (goal).
the move: it glides, yours would hold still
Vietnamese: money · written "ia", "iê", "ya", "yê"
One diphthong, spelled ia when nothing follows (kia) and iê when a consonant does (tiền).
Your /i/ is the one in iki (two).
the move: it glides, yours would hold still
Vietnamese: rain · written "ưa", "ươ"
ưa when final (mưa), ươ before a consonant (nước, người).
Your /ɯ/ is the one in kız (girl).
Words you may say identically
Two or more Vietnamese sounds landing on one sound of yours. Until the ear separates them, the mouth cannot — which is what the ear trainer is for.
Rhythm and pitch
The layer spelling never records, and the one that makes a correct sentence still sound foreign.
| Turkish | Vietnamese | |
|---|---|---|
| Rhythm | Syllable-timed, rising to the end | Syllable-timed, one tone per syllable |
| Stress | Regular by default: the last syllable, and it travels rightwards as suffixes are added (kiTAP, kitapLAR, kitaplarDAN). The exceptions are what make it a real system. Place names are stressed early, on a pattern borrowed from their shape (ANkara, İsTANbul, İZmir); many adverbs and old loans stay on the first syllable (ŞIMdi, YArın, LOkanta); and some suffixes refuse the stress and push it onto the syllable before them — the negative -me-/-ma- above all, so that the same letters can be a noun or a command. | 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. |
| Pitch | Not tonal. The stressed syllable is marked by a rise in pitch more than by loudness, which is why Turkish sounds even and melodic to an English ear. A yes/no question carries the particle mı/mi/mu/mü, and the pitch peak lands on the syllable just BEFORE it — on the word being asked about: Ahmet mi geldi? 'Was it AHMET who came?' against Ahmet geldi mi? 'Did Ahmet COME?'. The particle moves, and the melody moves with it. | lexical tone — pitch changes the word |
What you have that Vietnamese doesn't
11 sounds with no job in Vietnamese. 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 Turkish has a regional variety that already owns one of these, or that you learned Vietnamese from someone whose accent you copied. A teacher listening to you beats it. Use it to know what to listen for.
