Why does European Portuguese sound so different? The secret of the “swallowed” vowels

Many learners say European Portuguese sounds like Russian, or that Portuguese speakers “eat” half the word. There's a clear explanation, and once you know it, listening gets much easier.

Stressed vowels are clear, the others shrink

In European Portuguese, as a rule, only the stressed syllable keeps a full, clear vowel. The unstressed vowels are reduced: they become shorter and weaker, and some almost disappear. Brazilian Portuguese reduces far less, which is why it sounds more open and “sung”.

The unstressed e is the one that shrinks most. In everyday speech it is often barely heard:

The unstressed o usually sounds like u. Brazilians do this at the end of words too, but in Portugal it also happens before the stressed syllable:

The “sh” sound

The second big difference: an s at the end of a syllable sounds like “sh” in Portugal. Before a voiced consonant (b, d, g, m, n, l, r, v) it sounds more like the “s” in “measure”. In much of Brazil it stays a plain “s”; in Rio de Janeiro (and some other areas) the “sh” is the norm. Before a vowel in the next word it becomes a “z”: os amigos sounds like “uzamigush”.

What this means for you

First, don't panic: the words are the same ones you've learned, just pronounced faster and with weaker vowels. Second, train your ear with real European Portuguese, such as radio, podcasts and series from Portugal, not only with Brazilian material. Third, when you speak, you don't need to swallow your vowels to be understood. Clear Portuguese is perfectly fine; your ear just needs to catch up.
