Vietnamese → German
German uses 43 sounds. You already own 17 of them from Vietnamese. The other 26 are the work — and 25 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.

Words you may say identically
Two or more German 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.
German
Closest thing you own: — but plosive → affricate, alveolar → postalveolar.
Rhythm and pitch
The layer spelling never records, and the one that makes a correct sentence still sound foreign.
| Vietnamese | German | |
|---|---|---|
| Rhythm | Syllable-timed, one tone per syllable | Stress-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. | Contrastive in a very German way: with separable-vs-inseparable prefix verbs, the stress tells you which grammar you are in — and therefore what the sentence means. Otherwise stress sits on the stem syllable, and the unstressed prefixes (be-, ge-, er-, ver-, zer-, ent-) never take it. |
| Pitch | lexical tone — pitch changes the word | No lexical tone. Intonation marks questions, but German also inverts the verb, so the rise is doing less work than in Georgian or French. |
What you have that German doesn't
18 sounds with no job in German. 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 German from someone whose accent you copied. A teacher listening to you beats it. Use it to know what to listen for.
