Cantonese → Portuguese
Portuguese uses 35 sounds. You already own 11 of them from Cantonese. The other 24 are the work — and 22 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: velar → palatal
Portuguese: wine · written "nh"
Spanish writes this ñ, French gn, Portuguese nh.
Your /ŋ/ is the one in ngo5 我 (I).
the move: alveolar → postalveolar
Portuguese: key · written "x", "ch", "s (final)"
Also every syllable-final s: os livros = /uʒ ˈlivɾuʃ/.
Your /s/ is the one in sik6 食 (to eat).
the move: near-close → close
Portuguese: life · written "i"
Your /ɪ/ is the one in sing1 星 (star).
the move: near-close → close
Portuguese: everything · written "u", "o (final)"
Unstressed final o is /u/ — always.
Your /ʊ/ is the one in tung4 同 (same).
the move: close, but not identical
Portuguese: foot · written "e", "é"
Open e. The accent tells you which: pêlo vs pélo.
Your /ɛː/ is the one in se2 寫 (to write).
the move: close, but not identical
Portuguese: spade · written "a", "á"
Your /aː/ is the one in saam1 三 (three).
the move: close, but not identical
Portuguese: grandmother · written "o", "ó"
avó /ɔ/ grandmother vs avô /o/ grandfather — one accent apart.
Your /ɔː/ is the one in ngo5 我 (I).
the move: close, but not identical
Portuguese: wool · written "ã", "an", "am"
lá 'there' vs lã 'wool' — the nasality is the whole difference.

the move: near-close → close-mid
Portuguese: fear · written "e", "ê"
Your /ɪ/ is the one in sing1 星 (star).

Your /t/ is the one in daai6 大 (big).
the move: voiced
Portuguese: cat · written "g", "gu"
Your /k/ is the one in go3 個 ((classifier)).
the move: voiced

A real v, unlike Spanish where b and v merged.

Your /j/ is the one in jat1 一 (one).
the move: near-close → close, front → central

The vowel that vanishes. Often deleted outright, which is why European Portuguese sounds like a run of consonants.

the move: near-close → close-mid
Portuguese: time · written "em", "en"
Your /ɪ/ is the one in sing1 星 (star).
Words you may say identically
Two or more Portuguese 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 Cantonese 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.
| Cantonese | Portuguese | |
|---|---|---|
| Rhythm | Syllable-timed | Stress-timed (Portugal) |
| Stress | No contrastive stress; prominence comes from particles and from changed tone (變調) lifting a syllable to tone 2. | Contrastive and written. The default is the second-to-last syllable; anything else takes an accent, and the accent also picks between open and close vowels — avó /ɔ/ is a grandmother and avô /o/ is a grandfather. |
| Pitch | lexical tone — pitch changes the word | No lexical tone. Intonation carries questions on its own — Portuguese changes nothing else about the sentence, so the rise is doing all the work. |
What you have that Portuguese doesn't
31 sounds with no job in Portuguese. 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 Cantonese has a regional variety that already owns one of these, or that you learned Portuguese from someone whose accent you copied. A teacher listening to you beats it. Use it to know what to listen for.
