This proposal works on grids and constituents organized in a multidimensional plane ruled by phonological principles, which control the projections onto metrical grid. This approach aims at translating the properties of main stress of those languages, which deal with prosodic word final elements as extrametrical ones and also with those languages with the trissylabic window condition. This proposal will demonstrate that it is not necessary to make any reference to such aspects, since they will be naturally derived from the constraint hierarchy. The formulation of this model will be at priori subsidized by the main stress pattern of Brazilian Portuguese non-verbs and then it will be applied to other languages. / Este trabalho apresenta um modelo de an?lise m?trica com base em restri??es que opera com grades e constituintes organizados em um plano multidimensional governado por princ?pios que regulam as proje??es na grade m?trica. Esse modelo se pretende capaz de traduzir as propriedades do acento prim?rio das l?nguas que tratam elementos finais na palavra pros?dica como extram?tricos ou que possuam a condi??o da janela trissil?bica do acento. A proposta mostrar? que n?o h? necessidade de fazer refer?ncia a esses aspectos, uma vez que os mesmos ser?o naturalmente derivados da hierarquia de restri??es da l?ngua. A formula??o do modelo se sustentar?, inicialmente, no padr?o de acento prim?rio dos n?o-verbos do Portugu?s Brasileiro para, em seguida, ser aplicada a outras l?nguas.

A s?laba cvc e sua fun??o no sistema

Aquino, Carla de 13 January 2014 (has links)
Made available in DSpace on 2015-04-14T13:39:08Z (GMT). No. of bitstreams: 1 456597.pdf: 1368217 bytes, checksum: a743b677b015bce213c6ce97a87633f5 (MD5) Previous issue date: 2014-01-13 / This research was developed into the domain of linguistic theory and analysis, more specifically phonological studies, and aims at diferenciating light and heavy syllables in Portuguese. Quantity sensitive languages treat these two structures differently in relation to their role in processes such as stress assignment, tone, etc (GORDON, 2004). Tone or stress are rather assigned to heavy or bimoraic syllables (HYMAN, [1985] 2003; HAYES, 1989). Under this view, this research describes the behavior of CVC, which can be heavy in Portuguese, in the absence of long vowels, based on the process of stress assignment, a classical theme in the studies on phonological theory. Studies about stress in Portuguese meet no consensus on the role of weight for stress (CAMARA JR., 2007 [1970]; BISOL, 1992, 1994a; LEE, 1994; WETZELS, 1996, 2002, 2003, 2006; MAGALH?ES, 2004, 2010). The notion of contextually-dependent weight is necessary to describe stress, as in this work we treat weight as a relevant factor only at the right edge of the word (BISOL, 1992, 1994a; MAGALH?ES, 2004, 2010). Non-derived and derived items ended in CVC, in which final C is a sonorant [l,r,N] and the obstruent [S], compose the corpus of the study. They are all part of a 10.191 closed-syllable-word corpus. Once word final CVC usually behaves as strong, attracting main stress, we look for morphological reasons to justify the behavior of the exceptions. Thus, we argue that feet are constructed based on moras and that the stress rule in Portuguese is sensitive to the morphological structure of words, blocking weigth assignment to the terminal element in syllables which belong to specific morphemes. The analysis of the phonology/morphology interface in derived and non-derived items follows Pater (2000, 2004, 2007, 2009), counting on indexed constraints and considering inconsistencies as morphologically conditioned. Moreover, the dubious behavior of post-vocalic /S/, which is sometimes light, sometimes heavy, is as well discussed. Sonority constraints on moraic segments are verified (ZEC, 1998,1995, 2007). Optimality Theory, an output oriented model, which does not deal with rule ordering or derivation cycles, allows us to work with syllabification, weight and stress assignment in parallel. / Este trabalho insere-se no dom?nio da teoria e an?lise lingu?stica, mais especificamente dos estudos fonol?gicos, e tem como objetivo principal diferenciar s?labas leves e pesadas no portugu?s. L?nguas com sensibilidade quantitativa tratam essas duas estruturas diferentemente com rela??o ao seu papel em processos como acentua??o, tom, etc (GORDON, 2004). Nessas l?nguas, s?labas pesadas ou bimoraicas s?o preferencialmente as portadoras de acento ou tom (HYMAN, [1985] 2003; HAYES, 1989). Dentro desse panorama, este trabalho busca descrever o comportamento da s?laba CVC, que pode manifestar-se como pesada na l?ngua, na aus?ncia de vogais longas, a partir do processo de acentua??o no portugu?s, tema cl?ssico nos estudos em teoria fonol?gica. Nos estudos sobre o acento em portugu?s n?o h? consenso sobre o papel do peso na atribui??o de acento (CAMARA JR., 2007 [1970]; BISOL, 1992, 1994a; LEE, 1994; WETZELS, 1996, 2002, 2003, 2006; MAGALH?ES, 2004, 2010). A no??o de peso contextualmente dependente ? necess?ria para dar conta do acento, uma vez que, neste trabalho, em conformidade com Bisol (1992, 1994a) e Magalh?es (2004, 2010), trata-se o fator peso como relevante apenas na borda direita da palavra. Comp?em o corpus deste estudo itens n?o derivados e derivados terminados por s?laba CVC cujos elementos p?svoc?licos s?o as soantes [l,r,N], e a obstruinte [S], todos oriundos de um banco de dados composto por 10.191 palavras terminadas em s?labas fechadas. Como a estrutura CVC em posi??o final geralmente se manifesta como pesada na l?ngua, recebendo o acento principal, buscam-se justificativas de origem morfol?gica para o comportamento das exce??es. Defende-se, assim, que a forma??o de p?s ? realizada com base nas moras e que a regra de acento em portugu?s ? sens?vel ? estrutura morfol?gica dos termos, de modo a impedir a atribui??o de peso ao elemento terminal da s?laba quando na presen?a de determinados morfemas. A an?lise da interface fonologia/morfologia em itens derivados e n?o derivados fundamenta-se na proposta de Pater (2000, 2004, 2007, 2009) de restri??es indexadas, considerando a altern?ncia morfologicamente condicionada. Al?m disso, discute-se o comportamento d?bio do segmento /S/ p?s-voc?lico, que ora porta-se como leve, ora pesado, verificando os patamares de sonoridade para segmentos m?ricos atuantes na l?ngua (ZEC, 1998,1995, 2007). A Teoria da Otimidade, um modelo voltado para o output, que n?o conta com o ordenamento de regras ou ciclos na deriva??o, permite lidarmos com silabifica??o, atribui??o de peso e acentua??o paralelamente.
