BATTISTI, Elisa  e  GOMES DE OLIVEIRA, Samuel. THE RAISING OF VOWEL /a/ IN NASAL CONTEXT IN BRAZILIAN PORTUGUESE: PRELIMINARY STUDY. Lingüística [online]. 2019, vol.35, n.1, pp.35-55.  Epub 01-Jun-2019. ISSN 2079-312X.  https://doi.org/10.5935/2079-312x.20190003.

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
