Abstract

This thesis analyses some phonetic and phonological aspects of the glottalized sonorants of Dâw language. It argues in favor of the proposal that characterizes glottalization in Dâw language as a contrastive and a segmental property restricted to the class of the sonorant consonants (MARTINS, 2004). It describes more than one phonetic form for the glottalized consonants, mainly including creaky voice and harsh voice (ESLING; HARRIS, 2003). In general, the glottalized consonants are shorter, their glottal cycles have a more irregular waveform, they have smaller H1H2 and higher fundamental frequency (when creaky voice is absent) than the correspondent plain consonants. Except for the fundamental frequency levels, glottalization does not affect the acoustic properties of the neighbor segments. Glottalization is limited to or appears more noticeably in the parts of the consonants that are found at a greater distance from the neighbor vowels, a pattern that was also found in other languages (PLAUCHÉ et al., 1998). It was found that the increase in the fundamental frequency caused by glottalization does not restrict the tonal system in Dâw and the fundamental frequency levels of the lexical tones are prioritized. The phonetic confirmation of the process of syllable reduction described by Martins (2004) allows us to defend that glottalization and the glottal stop share the same feature or are defined by similar gestures, especially because the similarity is reinforced by the phonetic comparison between both phonemic entities and by the evaluation of the sonorant consonants in the neighborhood of the glottal stops. However, there is not sufficient information to sustain the proposal of Martins (2005) that the glottalized consonants in Dâw were originated merely from the incorporation of the glottal stop features by the plain consonants. Finally, this thesis notes that the occurrences of the glottalization types relate with the nasalization of the segments and the sex and the age group of the speakers. The relation between nasalization and glottalization type, as well as the glottalization timing, perhaps can be explained by aerodynamic and perceptual factors (GORDON; LADEFOGED, 2001). Nevertheless, this study was not able to deepen the understanding of the reasons for the aforementioned facts. The relation between sex, age group and glottalization type does not imply an ongoing change and demands further sociolinguistic research. (AU)
