Vietnamese → Hindi
Hindi uses 41 sounds. You already own 9 of them from Vietnamese. The other 32 are the work — and 24 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: palatal → retroflex
Hindi: tomato · written "ṭ", "ट"
RETROFLEX: tongue curled back. This is the one English speakers substitute for both — English t sits between the two and sounds foreign either way.
Your /c/ is the one in chào (hello / goodbye).
the move: palatal → retroflex
Hindi: Ganesh · written "ṇ", "ण"
Retroflex n.
Your /ɲ/ is the one in nhà (house).

Your /ɔ/ is the one in cho (to give; for).
the move: close, but not identical

Between English v and w and genuinely neither — which is why Hindi speakers of English swap the two.

The default vowel, built into every consonant letter unless something removes it.
Your /e/ is the one in đêm (night).
the move: voiced
Hindi: house · written "gh", "घ"
Breathy, not aspirated — voicing carries on through the breath.
Your /k/ is the one in cá (fish).
Words you may say identically
Two or more Hindi 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.
sunshine
Closest thing you own: — but alveolar → dental.
tree
The tongue flicks forward off the roof of the mouth. A single quick beat.
Closest thing you own: — but nasal → flap, palatal → retroflex.
tea
The word the whole world borrowed — chai, çay, chá.
Closest thing you own: — but plosive → affricate, alveolar → postalveolar.
small
Closest thing you own: — but plosive → affricate, alveolar → postalveolar.
to go
Closest thing you own: — but nasal → affricate, alveolar → postalveolar.
drum
Closest thing you own: — but palatal → retroflex, voiced.
night
A tap, as in Spanish pero.
Closest thing you own: — but nasal → tap.
a lie
Closest thing you own: — but nasal → affricate, alveolar → postalveolar.
Rhythm and pitch
The layer spelling never records, and the one that makes a correct sentence still sound foreign.
| Vietnamese | Hindi | |
|---|---|---|
| Rhythm | Syllable-timed, one tone per syllable | Syllable-timed, with deletion |
| 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. | Not contrastive and not written. Stress falls on the heaviest syllable — a long vowel or a closed syllable outweighs a short open one — and where several are equal it goes to the last of them. No two Hindi words are told apart by stress alone, which makes it the least stressful stress system here. |
| Pitch | lexical tone — pitch changes the word | No lexical tone, unlike its neighbour Punjabi, which developed one. Pitch does intonation, and क्या at the front of a sentence marks a question so the rise is optional. |
What you have that Hindi doesn't
26 sounds with no job in Hindi. 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 Hindi from someone whose accent you copied. A teacher listening to you beats it. Use it to know what to listen for.
