Picking up English as a Brazilian Portuguese speaker can feel surprisingly easy at first. Both languages use the same alphabet and even share a lot of similar vocabulary. But some natural habits from Portuguese can quietly make English harder to understand at times. Here are some of the most common challenges to watch out for.
Adding vowels and the /h/ sound
Brazilian Portuguese tends to add a small vowel sound after final consonants, so big becomes “biggy” and sit becomes “sitchy.” At the same time, because H is silent in Portuguese and R carries a breathy quality, English words starting with H may lose that sound entirely, while R words can gain an unexpected breathiness. Both habits require conscious effort to correct separately.
Vowel distinctions and TH sounds
Where Portuguese uses one clean vowel, English uses two — meaning ship and sheep, or sit and seat, can come out sounding identical. Minimal pair practice is the most effective fix. Similarly, the TH sounds in three and that do not exist in Portuguese and are commonly swapped for /f/, /v/, /d/, or /t/. Producing them correctly simply takes placing the tongue between the teeth until it feels natural.
Endings, nasality, and word stress
English words often end in complex consonant clusters like texts or strengths, while Portuguese words tend to end in open vowels — so endings frequently get dropped or simplified. Brazilian Portuguese also has rich nasal vowels that can carry over into English unintentionally. Finally, English word stress is less predictable than in Portuguese and shifts with word form, which can make even familiar vocabulary hard to recognise.
The Bottom Line
Brazilian Portuguese speakers already have several advantages when learning English, including shared vocabulary, familiarity with the alphabet, and a natural rhythm in speech. The challenges mentioned above are very specific and can absolutely be improved with practice. Focusing first on word endings, stress patterns, and TH sounds often leads to the quickest progress. A skilled pronunciation coach can also help identify the habits that show up most in your speech and provide targeted exercises to improve them.
