Academic literature on the topic 'Autosegmental theory (Linguistics)'

The aim of this paper is to defend the autosegmental account of nonconcatenative morphology originally proposed by McCarthy (1979, 1981), which has been seriously challenged by Hudson (1986). It is argued that an autosegmental analysis of nonconcatenative morphology such as that of Arabic still remains a better alternative than what Hudson proposes. We first present a brief overview of McCarthy's theory of non-concatenative morphology. We then review Hudson's criticisms of such an autosegmental approach to Arabic morphology and we end up by showing why his reanalysis does not constitute a better alternative than the criticized autosegmental account.

We develop a novel optimization approach to tone. Its grammatical component consists of the similarity- and proximity-based correspondence constraint framework of Agreement by Correspondence theory (ABC). Its representational component, Q Theory, decomposes segments ( Q) into temporally ordered, quantized subsegments ( q), which comprise unitary sets of distinctive features, including tone. ABC+Q unites phonological alternations and static lexical patterns, as we illustrate with a programmatic survey of core tonal phenomena: assimilation, dissimilation, lexical tone melodies, and consonant-tone interaction. ABC+Q surmounts long-standing problems for autosegmental-era, multitiered representational approaches to tone, and unites tonal and segmental phonology under the modern umbrella of correspondence theory.

Phonological coalescence, understood as a type of synchronic alternation in which two phonological elements seem to fuse into one, presents a prima facie challenge for versions of Optimality Theory that assume the principle of containment. If all underlying material has to be present in the output form, replacing two input elements with a single output element is not straightforward. I argue that, under the assumptions of Autosegmental Coloured Containment Theory, a distinct operation of coalescence is unnecessary, as all major types of coalescence patterns can be analysed in terms of (i) adding new association lines between some autosegmental nodes, and (ii) the underparsing of other nodes, leading to their phonetic non-realisation. The proposed analysis accurately reflects the heterogeneity of coalescence alternations, which are shown to fall into three different types.

In generative phonology, tone and nasality are described as suprasegmental phonological units. This implies that their survival depends on the segments on which they are grounded. Thus, when a tone bearing unit or nasality bearing unit disappears, any of these segments also disappears. In autosegmental theory, however, tone or nasality survives after the deletion of segment to which it is attached. This phenomenon is termed ‘stability’ which is the foundation for autosegmental phonological theory. Stability is the survival of tone and nasality after the deletion of segments on which they are grounded. Tone and nasality exhibit stability in Ikhin, a North-Central Edoid language spoken in Edo State, South-South, Nigeria. Previous study on Ikhin dwells mainly on the phonetics of the language. This study, therefore, investigates phonological processes such as vowel elision, glide formation and nasalization with a view to determining the stability or otherwise of tone and nasality. This paper confirms that in Ikhin, any process that involves the removal of a tone bearing unit must relate to stability and relate to the creation of contour tones. The study further confirms that nasality remains stable even in the absence of segment to which it is linked. Based on available data, it is argued that the deletion of a Tone Bearing Unit (TBU) or a Nasality Bearing Unit (NBU) does not necessarily involve the deletion of tone or nasality. Infact, it usual does not. The study concludes that tone and nasality are independent segments. They are as independent as consonant and vowel.

A morpheme, is a set of feature matrices dominated by a single node. Reduplication or gemination is one of the productive morphological processes which have been studied inclusively in different languages and in the frame of different linguistic theories like Generative Grammar, Optimality Theory and Minimalist Program. McCarthy's prosodic theory is justified by an analysis of the formal properties of the system of verbal processes like reduplication are the primary or sole morphological operations. This theory of nonconcatenative morphology recognizing the root as a discontinuous constituent. Under the prosodic model, a morphological category which characteristically reduplicates simply stipulates an output template composed of vowel and consonant. Consonantal roots and vocalic melodies in Arabic, although they contain bundles of the same distinctive features, can nevertheless be represented on separate autosegmental tiers. This ensures that the association conventions for melodies can operate independently on these two tiers. Association of autosegments from different tiers to the same segments will be subject to the natural restriction that no segment receives multiple associations for the same nontonal feature.

Three important strands of research characterise modern phonological theory; (i) the cyclic interaction of morphology and phonology; (ii) prosodic structure as it is built from segments into moras, syllables, feet and ultimately the phonological word; and (iii) the precise internal structure of segments, including feature geometry, how these features may reside on autosegmental tiers, and how they may be underspecified.

Traditional autosegmental accounts of tone mapping invoke three independent factors: morphological category, tone quality, and a phonological directionality parameter. This article argues that the evidence for phonological directionality must be reconsidered. The article introduces a theory of Optimal Tone Mapping, in which attested patterns derive solely from the interaction of morphological directionality with quality-sensitive markedness constraints. The more restrictive theory of tone association that results from eliminating constraints that impose phonological directionality provides a new typology of tone melody languages.

Abstract In Shanghai tone sandhi, with the exception of T5 (yangru) sandhi, a pitch-fall occurs at the second or third syllable of a phonological word (or a sandhi domain). Previous analyses argue that this is invoked by the insertion of a default Low tone to satisfy the Well-formedness Condition of the autosegmental theory. However, in the framework of the present autosegmental theory, that condition is no longer necessarily satisfied, and an alternative interpretation, adopting a boundary Low tone, has been suggested. To evaluate the appropriateness of the default and boundary interpretations, we compared pitch contours among di- to tetrasyllabic words in greater detail. The results show that, in T1 to T4 sandhi, disyllabic words tend to have lower pitch contours than tri- and tetrasyllabic words at the first and second syllables, and that, in tetrasyllables, minimum pitch values were constantly attested at the third syllable. These results indicate that in Shanghai tone sandhi, a boundary Low tone is assigned at the right edge of a phonological word, and it is further associated with the third syllable in tetrasyllables. This boundary interpretation further gives an appropriate explanation of the difference of the pitch-fall between Middle and New Shanghai.

This study proposes that metrical constituents are inherently headless and stress is autosegmental. Chapter 2 argues that, since stress is the only diagnostic for the presence of a metrical head, the latter is redundant and must be eliminated from phonological theory. Further arguments for the inherent headlessness of feet are cited fl:om the theory of prosodic morphology (McCarthy and Prince 1990, Crowhurst 1991b) and from the facts of Yidinʸ stress (Dixon 1977, Crowhurst 1991a, Crowhurst and Hewitt, to appear). Next, stress is shown to exhibit the following auto segmental properties: stability (Bedouin Hijazi Arabic) , morphemic stress (Spanish, Turkish, Tagalog) and the ability to float (Mayo, Tagalog). After comparing the properties of stress with those of autosegments, it is concluded that stress is an autosegment. Assuming that feet can be either disyllabic, bimoraic or iambic (Hayes 1991), the above conclusion predicts the existence of five types of binary stressed feet. These are the left- and right-stressed syllabic foot, instantiated by Warao and Mayo, respectively, the left- and right-stressed moraic foot, instantiated by Cairene Arabic and Turkish, respectively, and the iambic foot, instantiated by Hixkaryana. The asymmetric nature of the iamb is attributed to the Weight-to-Stress Principle (Prince 1990), which allows stress to be assigned directly to heavy syllables. Furthermore, this principle predict6 all and only the attested types of unbounded stress systems. Chapter 5 argues that stressless feet and unfooted stresses are instantiated in Mayo, and the theories of Halle and Vergnaud 1987a, b and Hayes 1987, 1991 are shown to be incapable of accounting for these facts. The autosegmental theory of stress advances phonological theory in three ways. First, it eliminates most of the principles and devices which up to now have been used only to describe stress, leaving only the abstract stress autosegment which is itself subject to the principles of autosegmental theory. Second, this approach attributes many of the apparent differences between stress and tone to differences in their respective domains rather than differences in their formal properties. Third, the autosegmental theory of stress facilitates the formalization of a number of stress systems with heretofore complex analyses, including Yidinʸ, Mayo, Cairene Arabic, Turkish, Khalkha Mongolian and Tagalog.

The importance of studying Latin to a better understanding of certain phonological aspects of Portuguese language goes further than just considering it as the mother language of our mother tongue . It is possible to high light the presence of Latin in our everyday usage of Portuguese through diachronic studies. Moreover, it is easier to understand many grammar rules by focusing the origin of the words analysed here. So, it is not coherent, as some people say, that Latin is a dead language , because Portuguese, as well as, Spanish, French, Italian, etc, is the survivance of vulgar Latin, which shows that the latin language is alive (REZENDE, 2003). Thus, this paper intends to present a description and an analisys of the phonological phenomenons along the Latin consonantal evolution system to Brazilian Potuguese, suported by the Autosegmental Theory, also considering traces that formed the internal structure of the consonants, and also the sonority scale in the organization syllabical items structure as determinants points to the phenomenon that occurred in the evolution of language. Through this approach it is possible not only to identify the behavior hierarchyc traces and the items of the Latin consonants system and those present in the Brazilian Portuguese, also to verify which phonological rules are in the consonantal composition of Brazilian Portuguese. From the proposed analysis, the process of palatalization proved to be the most productive in the diachrony of language, if compared to other phenomenons that contributed to the creation of the current system of consonants of Brazilian Portuguese: sound reinforcement, fricativization, degemination, palatalization and consonantization
A importância de estudar o latim para uma melhor compreensão de certos aspectos fonológicos da língua portuguesa vai além de apenas se considerar a língua latina como mãe de nossa língua materna. Através de estudos diacrônicos, é possível evidenciar a presença do latim no uso diário que fazemos do português, além de se poder compreender mais facilmente muitas regras gramaticais por meio de um olhar focado na origem das palavras que são alvo de análise. Assim, é incoerente a ideia defendida por alguns de que o latim é uma língua morta , já que o português, assim como o espanhol, o francês, o italiano, etc., é a sobrevivência do latim vulgar, o que mostra estar a língua latina mais do que viva (REZENDE, 2003). Logo, este trabalho objetiva a apresentação de uma descrição e análise dos fenômenos fonológicos ocorridos na evolução do sistema consonantal do latim ao português do Brasil (PB), tendo como suporte a Teoria Autossegmental, considerando os traços que formam a estrutura interna das consoantes e, ainda, a escala de sonoridade na organização dos constituintes silábicos como determinantes dos fenômenos que ocorreram na evolução da língua. Com essa abordagem, foi possível, além de identificar o comportamento dos traços hierarquicamente dispostos e constituintes do sistema de consoantes do latim e aqueles ainda presentes no PB, também verificar quais regras fonológicas se fizeram presentes na composição do sistema consonantal do português brasileiro. A partir da análise proposta, o processo de palatalização mostrou-se como o mais produtivo na diacronia da língua, em se comparando com os outros fenômenos que contribuíram para a constituição do atual sistema de consoantes do Português Brasileiro: sonorização, fricativização, degeminação, palatalização e consonantização
