No. of bitstreams: 1 Disserta??o - J?ssica.pdf: 3623972 bytes, checksum: c2e26a004a3ce1627bec7b7b28ec9dda (MD5) Previous issue date: 2017-01-19 / Conselho Nacional de Pesquisa e Desenvolvimento Cient?fico e Tecnol?gico - CNPq / This study aims at analyzing the conditioning of application of the raising of pretonic midvowels in porto-alegrense speech. Three samples of speech from VARSUL database were considered, they were collected between 1988 and 2009, compounded by adults, men and women with school level between elementary and college degree. From 6.468 tokens of vowel /o/ and 7.190 tokens of vowel /e/, it was noticed that back mid-vowel undergoes more to the studied process than front mid-vowel, although both vowels present low rates of applying the raising. The time difference between collecting the samples pointed to the regression of using the raising in the researched community. By the use of the tool Rbrul, the statistical results show that the raising in analysis is frequently focused in few lexical itens which share, to vowel /o/ the contexts of nasalized vowel, velar and labial consonants in the precedent position and nasal consonants in the following position and to vowel /e/, the contexts of beginning of word, affricate and front coronal consonants in the precedent position and velar and palatal in the following position. These results confirm those found in previous works (KLUNCK, 2007 and CRUZ, 2010). The investigation concerning frequency in Portuguese language (consulted in corpora Corpus Brasileiro e ASPA) of words from these samples indicated that more frequent words present more SMA (raising) phonetically motivated, which is in agreement with the hypothesis of Frequency-Implementation (PHILLIPS, 2001). / Este estudo busca analisar o processo vari?vel de al?amento de vogais m?dias pr?-t?nicas na fala de porto-alegrenses. Foram consideradas tr?s amostras de fala, pertencentes ao banco de dados VARSUL, coletadas entre 1988 e 2009, compostas por adultos, homens e mulheres, com n?veis de escolariza??o entre fundamental e superior. A partir de 6.468 ocorr?ncias para vogal /o/ e de 7.190 para vogal /e/, notou-se que a vogal m?dia posterior tende a sofrer mais o processo em estudo do que a vogal m?dia anterior apesar das taxas de uso serem baixas para ambas as vogais nas tr?s amostras analisadas. A diferen?a entre ?pocas de coleta das amostras indicou que o al?amento sem motiva??o aparente demonstra regredir na comunidade de fala em estudo. Com o aux?lio da ferramenta Rbrul, os resultados estat?sticos indicaram que o processo em an?lise tem maior ocorr?ncia concentrada em poucos itens lexicais que compartilham, para a vogal /o/, dos contextos de vogal alvo nasalada, segmentos velares e labiais na posi??o precedente e nasal na posi??o seguinte, e para a vogal /e/, dos contextos de in?cio de voc?bulo, segmentos africados e coronais mais anteriores na posi??o precedente e velares ou nasal palatal na posi??o seguinte, corroborando assim o apontado em trabalhos anteriores (KLUNCK, 2007 e CRUZ, 2010). A investiga??o a respeito da frequ?ncia na l?ngua portuguesa (realizada nos corpora Corpus Brasileiro e ASPA) dos voc?bulos que comp?em a amostra indicou que os voc?bulos mais frequentes apresentaram SMA foneticamente motivado, resultado que vai ao encontro da hip?tese da Frequ?ncia- Implementa??o de Phillips (2001).
