This current research approaches the vowel nasality, comparing Portuguese with Spanish, studying the cognate words in both languages. The interaction between the two languages comes from their origins and often Portuguese and Spanish speakers think that they share a similar phonetic system due to the great linguistic proximity. The Spanish vowel nasality sometimes is treated as nonexistent. Therefore, a literature review was done, showing different opinions about the studied phenomenon. This research shows, through a phoneticdescriptive approach, an investigation of the nasalized vowels occurrences in Portuguese. Then, it presents a phonetic system descriptive study of the nasalized vowels in Spanish. In order to establish a comparative study between the two languages, regarding the nasalized vowels, we showed occurrences of nasal and non-nasal vowels in similar contexts for both languages. The research subjects are five native speakers of Spanish and five native speakers of Brazilian Portuguese. In addition to auditory analysis and their respective phonetic transcription, an acoustic study of the most important cases for the research purposes was done through analysis performed with the software Praat for acoustic phonetic analysis. The privileged parameter in the acoustic analysis was the formant structure of the surveyed vowels. The results showed that also in the Spanish language nasalized vowels occurred in certain contexts and this is evident in the acoustic analysis. On the other hand, vowel nasalization in the Portuguese language does not exactly occur as in the Spanish language. A comparative table between the nasal vowels occurrences of the two languages clearly shows the differences and similarities between them
