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

Yes

The word "relatórios" is identical in both Brazilian and European Portuguese in terms of meaning, grammar, spelling, and usage. The only difference lies in pronunciation:

• Brazilian Portuguese: The vowels are more "open" and clearly articulated. The unstressed "e" in the first syllable is pronounced clearly, and the nasal diphthong "ões" is more resonant.
• European Portuguese: The pronunciation is more "closed" or "reduced." The unstressed vowels (like the "e" in re-) are often shortened or nearly silent, and the rhythm of the word is more staccato.
