Neste artigo, buscamos evidência acústica para a harmonia vocálica com base na existência de correlação entre os valores de F1 das vogais pretônicas e tônicas. XXXX & XXXX (2009) mostram que um /a/ tônico não desencadeia harmonia vocálica em dados de Minas Gerais, Espírito Santo e Goiás. Dados de Kentowicz & XXXX (2011), no entanto, sugerem que /a/ desencadeia harmonia em dados de Pernambuco. Neste trabalho, apresentamos uma hipótese preliminar, baseada na dispersão vocálica, acerca do comportamento de vogais tônicas baixas como gatilhos de harmonia pretônica. Nossa análise baseia-se na comparação feita entre dados de Salvador e Porto Alegre e os dados de São Paulo, Minas Gerais e Pernambuco de Kenstowicz & XXXX.
Although BP and EP place primary stress exactly at the same position, secondary stress positioning is remarkably different, as can be noticed below. The examples present some possible instances of secondary stress (rhythmic stress) placement in both European and Brazilian Portuguese according to native speakers of each of the varieties. The syllables bearing primary stress are in bold and those bearing secondary stress are underlined:( Hulst notes that, in the majority of languages, the assignment of primary stress does not depend on prior exhaustive footing. Indeed, the assignment of primary and secondary stresses in Brazilian and European Portuguese is clearly independent.In this paper we assume that primary stress in Portuguese is part of the language's lexical
