8. SPE • Rule-based. • Derivational: derivation from underlying to surface form. A  B / X__Y

9. OT • Constraint-based. • Development of generative phonology. • Very different way of representation. • Can be used for syntax and acquisition studies. • Aims at cognitive explanations.

10. Constraints are universal. • Languages differ in the ranking of constraints. • Constraints can be contradictory and can be violated.

11. Examples of derivational rules • DEVOICING:A voiced obstruent becomes voiceless after a voiceless obstruent. • ə-INSERTION:Insert [ə] between two adjacent sibilants in the same word.

12. Examples of constraints • *SIBSIB:sibilants cannot occur cnosecutively within a word. • *VOICEVOICE:consecutive obstruents must be identical in voicing within a syllable. • MAX-IO:deletion of segment is prohibited. • DEP-IO:insertion of segment is prohibited. • IDENT-IO:input segment and the corresponding output must be identical.

13. 2. Linear Phonology • Make the rules as general as possible. • Use “Distinctive Features” instead of individual sound segments when writing the rules.

14. Distinctive Features • The idea of Distinctive Features was first developed by Roman Jacobson (1896-1982) in the 1940s as a means of working out a set of phonological contrasts or oppositions to capture particular aspects of language sounds. Since then several versions have been suggested.

15. Major class features • consonantal (con): sounds produced with a major obstruction in the oral cavity. • approximant (approx): sounds made with an oral tract constriction which is less than that required to produce friction. • Vowels, glides and liquids are [+approx], other sounds are [-approx]. • Also known as syllabic (syl) to indicate that they can form a syllable peak. • sonorant (son): sounds produced with a vocal tract configuration in which spontaneous voicing is possible. • Obstruents (plosives, affricates and fricatives) are [-son], other sounds are [+son].

16. Vowel place features • high: the body of the tongue is raised from the neutral position. • low: the body of the tongue is lowered from the neutral position. • back: the body of the tongue is retracted from the neutral position. • round: the lips are protruded. • tense: sounds requiring deliberate, accurate, maximally distinct gestures that involve considerable muscular effort.

17. advanced tongue root (ATR):vowels made by drawing the root of the tongue forward, thus enlarging the pharyngeal cavity, tending to raise the tongue body, and tending to give the sound a more tense articulation, e.g. [i e o u]. • [-ATR] sounds lack this gesture, e.g. [I E ç U a A].

18. Consonant place features • labial (lab): Sounds that involve a constriction of the lips to give either a labial (labiodental) consonant or a rounded vowel/glide. • coronal (cor): produced with the blade or tip of the tongue raised from the neutral position. • anterior (ant): defined only for coronal sounds. An anterior ([+ant]) sound is made with a constriction at or forward of, the alveolar ridge. Posterior ([-ant]) sounds are produced behind the alveolar ridge. • The anteriors are the dentals and alveolars, the posterior sounds are the retroflex, palato-alveolar and palatal sounds.

19. dorsal (dor): Sounds made by raising the dorsum (tongue body) towards the hard palate, the soft palate (velum) or the uvula. • The dorsal consonants are the velars and uvulars. • radical (rad): Sounds produced in the pharyngeal or laryngeal (glottal) region, e.g.

20. strident (strid): produced with a construction with greater noisiness. • Stridency is only defined for fricatives and affricates. • Labiodentals, sibilants and uvular fricatives/ affricates are [+strid]; all other fricatives/affricates are [-strid].

21. Manner features • continuant (cont): the primary constriction is not narrowed so much that airflow through the oral cavity is blocked. • Plosives and nasal stops are [-cont], other sounds (including laterals) are [+cont]. • nasal (nas): the velum is lowered which allows air to escape through the nose. • lateral (lat): the mid section of the tongue is lowered at the side.

22. Laryngeal features • voice: the vocal folds vibrate. • spread glottis (spread, or s.g.): the vocal folds are spread far apart. • Aspirated (voiceless) consonants, breathy or murmured voiced consonants and voiceless vowels/glides are [+spread]; other sounds are [-spread]. • Also known as aspirated.

23. Distinctive feature matrix for English consonants

24. Now we can represent the rule that governs the unaspiration of /p/ after [s] in terms of features:

25. Past tense forms in English • stopped, walked, coughed, kissed, leashed, reached • stabbed, wagged, achieved, buzzed, soothed, bridged • steamed, stunned, pulled • played, flowed, studied • wanted, located, decided, guided

26. The regular past tense form in English is pronounced as [t] when the word ends with a voiceless consonant, [d] when it ends with a voiced sound, and [ɪd] when it ends with [t] or [d].

27. Plural rule • z   / [-voice, +cons]______ (Devoicing) •   /咝擦音_____z (增音) • z  z 剩余位置

28. Obligatory Contour Principle (OCP) • Obligatory Contour Principle • No identical adjacent autosegments. (Goldsmith 1976)

29. 3. Non-linear Phonology • These theories began as a method for representing prosodic features such the stress in complex words, so that their different levels of stress are represented not by linear orders but by a metrical grid:

30. Later the method was extended to the representation of earlier linear rules.

31. Plural rule (1) [+cons] [+cons] [-son] root [-son] plural z Laryngeal Laryngeal [-voice] [+voice]

32. Plural rule (2) Ø  X /X____________X [-cons] [+cons] [+cons] [+strid] [+strid] [COR] [COR]

33. Past tense rule (1) [+cons] [+cons] [-son] root [-son] past d Laryngeal Laryngeal [-voice] [+voice]

34. Past tense rule (2) Ø  X /X__________X [-cons] [+cons] [+cons] [-cont] [-cont] [-nas] [-nas]

35. 4. OT • The ranking of the constraints is represented by a “tableau”.

36. Review of some constraints • *VOICEVOICE:consecutive obstruents must be identical in voicing within a syllable. • DEP-IO:insertion of segment is prohibited. • IDENT-IO:input segment and the corresponding output must be identical. • OCP:No identical adjacent autosegments.
