This study uses musical notation to describe speech prosody in connected speech in Brazilian Portuguese and Mexican Spanish, using English as a comparison where needed. Through this research we establish the basis on which to expand our future work on speech prosody, from methodology to data collection and analyses, and then make initial observations regarding potentially significant prosodic patterns. This study shows that musical notation can inform us about: 1) the pitch ranges of the speakers in connected speech; 2) speech rate; 3) patterns of moraic and non-moraic syllables; 4) syllable timing; 5) intonation patterns, especially speakers' tessitura. The methodology that we have developed in this exploratory study may help solve unpredictable patterns of speech prosody, especially in regards to intonation, and consequently lead to the improvement of current speech prosody models.

This work, which is couched in the theoretical framework of Articulatory Phonology, deals with the influence of speech rate on the change/variation from antepenultimate stress words into penultimate stress words in Brazilian Portuguese. Both acoustic and articulatory (EMMA) studies were conducted. On the acoustic side, results show different patterns of post-stressed vowel reduction according to the word type. Some words reduced their medial post-stressed vowels more than their final post-stressed vowels, and others reduced their final post-stressed vowels more than their medial post-stressed vowels. On the articulatory side, results show that the coarticulation degree of the poststressed consonants increases with speech rate. Also, with the use of a measure called proportional consonantal interval (PCI), it was found in measurements of articulation that such measure is influenced by the word type. Three different groups of words were found according to their PCI. These results show how dynamical aspects influenced by speech rate increase are related to the lexical process of change/variation from antepenultimate stress words into penultimate ones.

Esse trabalho descreve e investiga o sistema vocálico do dialeto capixaba para a fala feminina e o compara com o sistema vocálico, também feminino, do inglês norte-americano. Para que essa comparação se realizasse, foram feitas análises acústicas das vogais de ambas as línguas estudadas, através de suas frequências formânticas. O grupo de informantes foi composto por oito mulheres, sendo quatro capixabas e quatro norte-americanas nascidas no estado de Kansas. Todas as informantes pertenciam à faixa etária dos 20 aos 40 anos, com curso superior completo, ou por concluir. O corpus foi obtido por meio de gravações e leitura de frases-veículo. O ambiente fonético foi controlado para que o padrão de coarticulação fosse mantido. Os resultados, aqui apresentados, poderão dar suporte a futuros estudos em linguística aplicada relacionados à aquisição do inglês como língua estrangeira, bem como a estudos sobre o dialeto capixaba.
