Elevação Da Vogal /a/ Em Contexto Nasal Em Português Brasileiro

This study approaches the raising of vowel /a/ in nasal context in Brazilian Portuguese. We discuss the phonological representation of nasal vowels, compare Portuguese and Spanish with regard to the production and perception of nasal vowels, and conduct a preliminary, qualitative acoustic inspection of realizations of vowel /a/ in nasal and oral contexts. When discussing the representation of nasal vowels in Portuguese, we justify the acceptance of the hypothesis of the sequence /vN/ in the base of nasal /a/ and support the interpretation of vowel nasalization and nasalized vowel raising as phonologically derived processes. The acoustic inspection of vowel /a/ in nasal context shows that the vowel may or may not have nasal acoustic cues. This fact is motivated both phonetically and phonologically. The different realizations of vowel /a/ in nasal context obscure their linking to the bisegmental sequence in the base
