  1. SS-2006: Session 4 Phonological Theories Autosegmental / Metrical PhonologySegmental description

  2. The Segmental Tier The tree structures defining the feature geometry of sounds in language (N.B. I am not using the term „phoneme“) grow out of the „root“ node. That is the node which brings together all the feature information. I.e., it represents the whole segment (so for shorthand, we could write the transcription symbol there). But what is the function of the node? It is the link to the rest of the (phonological) system in anautosegmental (metrical) phonology. The “rest of the system“ means the structures above the level of thesingle sound = syllable level, prosodic word, phrase ...... Etc.

  3. Segments: phonetic structure vs. function The phonetic properties of a sound segment are not always clear in defining it as a consonant or a vowel!(N.B., vowel + consonant(s) are the elements making a syllable)  Approximants (a.k.a. „vowel glides“) are vowels, articulatorily Sonorants (nasals and laterals) can become syllabic Two different vowel qualities can, together, form one vowel Two different consonantal articulations can, together, form one consonant There seems to be a need for a functional descriptive levelbetween segment and syllable! The „skeletal tier“

  4. Syllable  CV tier C C V C V C V C C C V C C Segmental S v a I g  n I s t g  l t tier Function of the CV (skeletal) Tier [aI] is defined here as the vocalic nucleus of the syllable [SvaI]as opposed to[aI] in (e.g.) „Schwa in der Mitte“, where it is divided over two syllables [n] is defined here as the consonantal coda of the syllable [gn]. But if schwa is elided, it takes over the nuclear (V function of thesyllable

  5. Syllable  CV-tier C C V C V C Segmental S v a I g  n tier Function of the CV (skeletal) Tier • Every syllable has one V element • (ii) The V-element can be complex (e.g. [aI]) • (iii) If a vowel segment is elided (e.g. schwa-elision):SvaIgnSvaIgNanother segment must be associated with the V-element This representation corresponds in function to the SPE-rules for „schwa-elision" and the application of the feature [+syllabic]

  6. Change of Segmental Structurein autosegmental phonology The change of function within the syllable does not change thephonetic nature of the sound.It can therefore be represented without referring to the feature properties of the sound. But most phonological changes are changes of phonetic structure. e.g.: voiced becomes devoiced alveolar becomes labial or velar a stop becomes a fricative To represent these changes, we need to refer to the features, which constitute the tree linked to the skeletal tier via the root node

  9. SPE features The criticism of the unordered bundle of features in SPE-Phonology stems from the observation that the transformation rules allowed apparently arbitrary changes of the feature structure. A phonological rule should be a justifiable, describable phoneticgeneralisation. This is the argument for the hierarchical structure of featureswhich Clements, Halle and others proposed, and which mirror the articulatory organisation of the features (more or less).

  10. Structural change practice 1. How would the structural change for the following expressions be represented (in partial analogy to the previous slide)? sieben [zibm] es steht gut  [Es Stek gut]  [ES Stek gut] lieblich  [liplIC] vs [liblIC] Schicksal  [SIkzal] vs. [SIksal] leidig [laIdIC] vs. [laIdIk] 2. Discuss how the structural change for the following expressions might be captured: Haben Sie Lust? [hamzilUst] Hast Du einen Moment Zeit?  [hasnmomEntsaIt]
