These principles not only define phonlogy set of theoretically possible inter-tier configurations; they also trigger the operation of a set of universal repair mechanisms, often termed Association Conventions, whenever configurations that violate them arise.
Autosegments were introduced by John Goldsmith in his M. Retrieved from " https: Environments can be shown by placing other connected sets of features around that which is the focus of the rule.
The Well-Formedness Condition, at the very core of the autosegmental framework, was a rare constraint, posited nearly two decades before Optimality Theory. If you are a student or academic complete our librarian recommendation form to recommend the Oxford Research Encyclopedias to your librarians for an institutional free trial.
What is a Autosegmental Phonology | SIL Glossary of Linguistic Terms
Similar behaviors are widespread in long-distance phenomena, including intonation, vowel harmony, and nasal prosodies, as well as more locally with partial or full assimilation across adjacent segments. In this framework, phonological representations consist of parallel tiers of phonological segments, both tonal and segmental.
Using it for such rules makes the relationship between the result of the rule and the environment obvious. Later work modified many of the key properties zutosegmental the autosegmental model.
The autosegmental framework captured this naturally, since a sequence of elements on phonologgy tier can be connected to a single element on another. For a more recent overview and several new proposals, see Goldsmith Optimality Theory has led to a radical rethinking of autosegmental mapping, delinking, and spreading as they were formulated under the earlier derivational paradigm. Rather than classify segments using the categories given in the International Phonetic Alphabetthe autosegmental formalism makes use of distinctive features, which provide greater granularity and make identification of natural classes easier.
The autosegmental formalism deals with several separate linear sequences; because of this, a phonological representation is depicted on several distinct tiers. On such a view, phonological representations consist of more than one linear sequence of segments ; each linear sequence constitutes a separate tier.
As a theory of the dynamic of phonological representations, autosegmental phonology includes a Well-formedness Condition on association lines each element on one tier that "may" be associated to an element on another tier "must" be associated to such an element, and association lines do not cross plus an instruction as to what to do in case of a violation of the Well-formedness Condition: There are situations in which the rule applies not to a particular value of a feature, but to whatever value the feature has.
The stress tier contains the features that show the distribution of stress in the phonological representation. In This Article 1. In the segmental tier, features are assigned to segments. A further innovation of autosegmental theory is the set of universal principles termed Well-Formedness Conditions, which govern the multi-tiered structure of the representation.
In this conception, which draws upon earlier research in Metrical Phonology and Prosodic Phonology. Don't have an account? The co-registration of elements or autosegments on one tier with those on another is represented by association lines.
Autosegmental phonology - Wikipedia
Clements developed a number of influential aspects of the theory involving harmonic processes, especially vowel harmony and nasal harmony, and John McCarthy generalized the theory to deal with the conjugational system of classical Arabicon the basis of an autosegmental account of vowel and consonant slots on a central timing tier see also nonconcatenative morphology.
No more specification is necessary because place is phpnology only feature of the following segment that factors into the rule. If you have phonilogy a print title that contains an access token, please autosegmentap the token for information about how to register your code. One-to-many associations and spreading onto adjacent elements are characteristic of tone but not confined to it. There is a close relationship between analysis of segments into distinctive features and an autosegmental analysis; each feature in a language appears on exactly one tier.

The autosegmental formalism can be especially useful autosemental describing assimilation rules. The rule is that a coronal nasal will assimilate to the place of the following consonant. The early autosegmental notion of tiers of representation that were distinct but conceptually equal soon gave way to a model with one basic tier connected to tiers for particular kinds of articulation, including tone and intonation, nasality, vowel features, and others.
The autosegmental formalism departs from the depiction of segments as matrices of features in order to show segments as connected groups of individual features.
