Understanding Vowel Sounds in Portuguese

The Portuguese language has seven main oral vowels: a, e, i, o, u, plus the nasalized versions. The vowels “e” and “o” are particularly interesting because they can be pronounced as either open or closed, depending on their position in a word and sometimes the word’s etymology. The difference between open and closed vowels can change the meaning of words, making it an essential aspect of pronunciation.

What are Open and Closed Vowels?

Open Vowels

Open vowels are pronounced with the mouth more open, allowing more air to pass through. In Portuguese, the open vowels are:

The sound is more relaxed, and the tongue is placed lower in the mouth.

Closed Vowels

Closed vowels are pronounced with the mouth less open, and the tongue is closer to the roof of the mouth. In Portuguese, the closed vowels are:

The sound is tenser, and the lips may be more rounded, especially for “o”.

Rules for Open and Closed Vowels in Portuguese

1. Accent Marks

Portuguese uses accent marks to indicate whether a vowel is open or closed. The acute accent (´) signals an open vowel, while the circumflex accent (ˆ) indicates a closed vowel.

For example, “avó” (grandmother) has an open “ó”, while “avô” (grandfather) has a closed “ô”.

2. Syllable Position

The position of the vowel within the word can affect whether it is open or closed. Generally, stressed vowels at the end of a word tend to be open, but there are exceptions. In unstressed syllables, “e” and “o” are usually pronounced as closed vowels or even as reduced sounds similar to the English schwa.

3. Word Origin and Etymology

Sometimes, whether a vowel is open or closed is determined by the word’s origin or traditional pronunciation. For example, in many words of Greek or Latin origin, the vowel quality follows established patterns that learners will gradually recognize through exposure and practice.

4. Regional Variations

It’s important to note that pronunciation can vary by region. For example, in European Portuguese, the distinction between open and closed vowels is more prominent than in Brazilian Portuguese, where regional accents may blur these differences. Listening to native speakers from different regions is an excellent way to become familiar with these variations.
