Popular English Pronunciation Mistakes for Portuguese Speakers

Many Portuguese speakers learn English with strong reading and grammar skills. Still, pronunciation can feel difficult because Portuguese and English use different sound systems. Some English sounds do not exist in Portuguese. Other sounds exist, but they work in a different way.

This guide explains the most common English pronunciation mistakes for Portuguese speakers, why they happen, and how to practice them. The goal is not to remove your accent. The goal is clear, confident English.

Why English Pronunciation Is Difficult for Portuguese Speakers

Portuguese and English share some vocabulary roots, but their sound systems differ in important ways. A contrastive study of Portuguese and English explains that pronunciation problems often come from sounds that transfer easily from the first language and sounds that have no clear match in the second language.

Research on Brazilian Portuguese speakers learning English has identified several persistent pronunciation challenges, including /θ/, /ð/, /ŋ/, /æ/, syllable stress, extra syllables, and past-tense -ed endings. These patterns explain many English pronunciation problems for Portuguese speakers.

Portuguese also varies across countries and regions. A Brazilian Portuguese speaker and a European Portuguese speaker may not have the same accent patterns in English. Still, the problems below are common enough to deserve focused practice.

Common English Pronunciation Mistakes for Portuguese Speakers

1. “Th” Sounds: /θ/ and /ð/

One of the most common English pronunciation mistakes for Portuguese speakers is trouble with “th.” English has two “th” sounds: /θ/ in think and /ð/ in this. Portuguese does not use these sounds as native phonemes.

Portuguese speakers may replace /θ/ with /s/, /t/, or /f/. They may replace /ð/ with /z/, /d/, or /v/. This can make think sound like sink, or this sound like zis.

Practice words:

• think

• three

• both

• this

• they

• mother

Practice sentence:
I think they both took a bath at three.

Tip: Put your tongue lightly between your teeth. Push air out for /θ/. Add voice for /ð/.

2. The /æ/ Sound

English /æ/, as in cat, man, and bad, can be difficult because Portuguese does not use this exact vowel in the same way. Some Portuguese speakers may pronounce cat more like ket or cut. Research on Brazilian Portuguese speakers identifies /æ/ as one of the English sounds that remained difficult even after instruction and practice.

Practice words:

• cat

• bad

• man

• apple

• happy

Practice sentence:
The happy man had a black cat.

Tip: Open your mouth more than you would for /e/. Lower your jaw and keep the vowel short.

3. “Ng” /ŋ/ at the End of Words

English uses /ŋ/ at the end of words like sing, long, working, and morning. Portuguese speakers may add a /g/ sound after it, so sing sounds like sing-g. They may also change it to /n/.

Practice words:

• sing

• long

• bring

• morning

• working

Practice sentence:
I am working this morning and singing a long song.

Tip: For /ŋ/, lift the back of your tongue, as in the end of sing. Do not release a hard /g/ after it.

4. Extra Vowels in English Words

Portuguese often favors clear vowels, and Brazilian Portuguese in particular may add vowel sounds in places where English does not. This can create extra syllables. In one study, Brazilian Portuguese speakers added extra syllables in words such as speak, making the word sound longer than expected.

This can happen at the beginning, middle, or end of English words.

Practice words:

• speak

• school

• stop

• asked

• worked

Practice sentence:
She stopped and asked to speak at school.

Tip: Say the consonants slowly first. Then remove any extra vowel sounds.

5. Past-Tense -ed Endings

English past-tense -ed has three pronunciations:

• /t/ after voiceless sounds: worked, asked, watched

• /d/ after voiced sounds: played, called, loved

• /ɪd/ after /t/ or /d/: wanted, needed, started

Portuguese speakers may pronounce -ed as a full extra syllable too often. For example, worked may sound like “work-ed.” Research on Brazilian Portuguese speakers found that pronouncing -ed as a separate syllable was a persistent pronunciation issue.

Practice words:

• worked

• played

• asked

• loved

• wanted

• needed

Practice sentence:
I worked late, played music, and needed rest.

Tip: Only use /ɪd/ after /t/ or /d/. In most other words, -ed is not a full syllable.

6. English Word Stress

Portuguese speakers may place stress in a way that sounds natural in Portuguese but unusual in English. English uses strong word stress. One syllable is usually longer, louder, and clearer.

For example:

• TAble

• aBOUT

• COMputer

• imPORtant

• proNUNciation

In the Brazilian Portuguese learner study, syllabic emphasis was one of the pronunciation problems observed across the students. This is why English pronunciation for Portuguese speakers should include rhythm and stress, not only individual sounds.

Practice sentence:
English pronunciation needs lots of support.

Tip: Mark the stressed syllable before you say a new word. Make that syllable stronger and clearer.

Quick Pronunciation Practice for Portuguese Speakers

Use this 10-minute routine:

1. Choose one sound, such as /θ/ or /æ/.

2. Practice five words with that sound.

3. Say one short sentence slowly.

4. Record yourself.

5. Listen only for the target sound.

6. Repeat the sentence three times.

7. Use Syranto to check your speech and track your weak sounds.

Focused pronunciation practice for Portuguese speakers works best when you train one pattern at a time.

FAQ

What English sounds are difficult for Portuguese speakers?

Common difficult areas include “th” sounds, /æ/, final /ŋ/, consonant clusters, past-tense -ed endings, extra vowels, and English word stress. These sounds are difficult because Portuguese and English use different sound categories and syllable rules.

How can Portuguese speakers improve English pronunciation?

Start with the sounds that affect clarity most. Practice “th,” /æ/, /ŋ/, word stress, and -ed endings. Record yourself and compare your speech to a clear English model.

Can I reduce my Portuguese accent in English?

Yes. You do not need to remove your accent completely. Focus on the specific English pronunciation mistakes for Portuguese speakers that affect understanding, then practice them with short words, sentences, and feedback from Syranto.
