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 becom

es voiceless after a voiceless obstruent. -INSERTION:ə Insert [ ] between two aə

djacent sibilants in the same word.

12

Examples of constraints

*SIBSIB: sibilants cannot occur cnosecutively within a word.

*VOICEVOICE: 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 correspon

ding output must be identical.

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 wit

h a major obstruction in the oral cavity. approximant (approx): sounds made wit

h an oral tract constriction which is less than that required to produce friction. Vowels, glides and liquids are [+approx], oth

er sounds are [-approx]. Also known as syllabic (syl) to indicate that t

hey can form a syllable peak.

16

Major class features

sonorant (son): sounds produced with a vocal tract configuration in which spontaneous voicing is possible. Obstruents (plosives, affricates and fricati

ves) are [-son], other sounds are [+son].

17

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.

18

Vowel place features

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].

19

Consonant place features labial (lab): Sounds that involve a constricti

on 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.

20

Consonant place features dorsal (dor): Sounds made by raising th

e dorsum (tongue body) towards the hard palate, the soft palate (velum) or the uvula. The dorsal consonants are the velars and uv

ulars. radical (rad): Sounds produced in the p

haryngeal or laryngeal (glottal) region, e.g.

21

Consonant place features

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].

22

Manner features continuant (cont): the primary constric

tion is not narrowed so much that airflow through the oral cavity is blocked. Plosives and nasal stops are [-cont], other s

ounds (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 tong

ue is lowered at the side.

23

Laryngeal features

voice: the vocal folds vibrate. spread glottis (spread, or s.g.): the voca

l folds are spread far apart. Aspirated (voiceless) consonants, breathy o

r murmured voiced consonants and voiceless vowels/glides are [+spread]; other sounds are [-spread].

Also known as aspirated.

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