Is the word vezes the same in Brazilian and European Portuguese?

Yes

The word "vezes" is identical in meaning, grammar, and spelling in both Brazilian and Continental Portuguese. The only differences lie in pronunciation:

• Vowels and Rhythm: Brazilian Portuguese tends to have more open vowels and a "syllable-timed" rhythm, making the "e" in vezes sound more distinct. Continental Portuguese is "stress-timed," meaning unstressed vowels are often reduced, clipped, or even swallowed, making the final syllable sound much shorter or more neutralized.
• Phonetics: In many regions of Portugal, the final "es" may be pronounced with a very closed, almost unnoticeable vowel (resembling a "sh" sound), whereas in Brazil, it is typically more clearly articulated.
