Metrical Stress Theory Julie Nelson, Cailey Moe, and Trang Nguyen
Metrical phonology is... • ...a group of subtheories of generative phonology which attempt to categorize stress and stress rules. • ...differs from generative phonology in that it does not treat stress as a segmental feature pertaining specifically to vowels. • ...organizes stress into rhythmic hierarchies.
a brief history... • ...metrical stress theory was a response to Chomsky & Halle's (1968) proposal of a linear analysis that stress is segmental. • ...Liberman (1975) created the theory in his doctoral dissertation • ...other major contributions: Liberman & Prince (1977), Halle and Vergnaud (1978), Hayes (1981,1984, 1995)
a brief history... • ...it can be considered a sort of sister theory to auto-segmental theory • ...its authors sought to provide alternatives to generative theory such as rule variables • ...another way to represent stress in stress languages at the same time denoting its hierarchical characteristics.
briefly,generative theories of stress • -Generative stress rules are linear and may be considered too simplistic by some • -Stress is treated as a segmental feature • [+stress], [-stress], [1stress], [2stress] • -Doesn't account for the hierarchical and relational properties of stress
A sample stress rule (generative) • Penultimate stress (vowel-counting version) • V → [+stress] / ___ C0 V C0 ]word • Assign stress to the second-to-last vowel in the word.
Building Syllables • All syllables have: • An onset: "The consonant or sequence of consonants at the beginning of a syllable" • A coda:"The consonant or sequence of consonants at the end of a syllable" • And a nucleus:"The vowel or diphthong found at the syllable's core and functioning as its sonority peak"
Syllable Construction • When building syllables, first assign the nucleus!
Syllable Construction • Next, attach any consonants to the following syllable:
Syllable Construction • Finally, if necessary, attach any consonants not yet syllabified with the preceding syllable:
In some languages, Onset Formation appears to be word bounded, like in German:
Syllable Construction • In other languages, like Spanish, Onset Formation can cross word boundries:
Syllable Weight • Heavy Syllables: • End in a consonant (aka 'closed syllable') • Have a long vowel or diphthong (aka 'open') • Light Syllables: • End in a short vowel (open) • Syllables that end in a consonant are heavy, ones that end in a vowel are light.
More about syllables... • Every syllable must have a nucleus. Depending on the language, onset and coda are not required. • Arabic:Every syllable must have an onset • Samoan: codas are illegal
Metrical Theories of Stress • A summary of the typological properties of stress: • Culminativity: • Every content word has to have at least 1 stressed syllable • In every word or phrase there is one syllable which is stronger than the rest • Stress is not usually assigned on grammatical words • Rhythmic distribution: • Syllables bearing stress tend to occur in roughly equal distances • Stress Hierarchies: • Some stresses are stronger than others within a word or phrase boundary (primary, secondary, tertiary stresses, etc.) • Non-assimilation • Stress doesn't assimilate like sound features like [round] or [front] do
Metrical representations of stress • 1. Metrical tree (Liberman 1975, Liberman & Prince 1977, Hayes 1984) • Metrical trees usually have a similar format to syntactic trees
Metrical Representations of Stress • 2. Metrical Grid (Liberman & Prince, 1977) • Primary stress • Secondary stress • syllable => • 3. Bracketed Grid (Halle & Vergnaud, 1987)
Grids, continued • Grids are ways to represent certain stress phenomena:
Grids, continued • Grids roughly correspond to the categorical levels of stress • In this way, they convey similar information to what can be found on trees
Parameters of Stress Representation • 1. Foot Boundedness • 2. Foot Dominance • 3. Quantity-sensitivity • 4. Directionality vs Iterativity
1. Boundedness • Motivated by culminativity and exhaustivity. • Culminativity: Every content word must have at least one stress. • Exhaustivity: Every syllable has to be organized into feet. • Bounded feetcan have no more than 2 syllables (feet are binary or degenerate at the syllabic level of analysis). • Unbounded feet can have any number of syllables. • Words with an odd number of syllables begin or end with a degenerate foot.
1. Boundedness • Ex: What types of foot are these?
2. Foot Dominance • Left dominance: • left nodes of feet are stressed • Feet are trochaic (a) • Ex: 'problem, ('holi)day, • ('alter)('nation) • 'what a ('failure) • Right dominance: • Right nodes of feet are stressed • Feet are iambic (b) • Ex: re'port, • (com'puter) • (ex'treme)mity • (My 'head) (was 'hot)
3. Quantity Sensitivity (Q-sensitivity) • Syllable weight influences how stress feet are assigned. • Q-sensitive language: heavy syllables get stressed. • English is Q-sensitive: • Light penult: stress goes to preceding syllable. • Ex: 'Canada, 'metrical, 'visible, 'ultimate • Heavy penult: gets the stress • Ex: A'genda, ho'rizon, de'cided, 'mango • Q-determined (Obligatory Branching): means Q-sensitive, but with the extra requirement that the dominant syllable node be heavy.
3. Quantity Sensitivity (Q-sensitivity) • Q-insensitive language: heavy syllables may occur in stressless position. Another way of understanding: syllables are treated as having equal weight. • French is Q-insensitive. Examples anyone?
4. Directionality vs Iterativity • Directionality: The assignment of feet starts from the left and goes right or vice-versa • English likes right-to-left, trochaic foot formation. • Ex: restoration => resto('ration) => ('resto)('ration) • Iterativity • Iterativity (bidirectionality): assign a foot at one edge, then go to the other edge and assign feet iteratively. • Ex: Piro language • Non-iterativity: other cases (words have one single foot at the edge. Ex: monosyllable or bi-syllable words)
Extrametricality • [X] does not conform to metrical rules & occurs at peripheral locations. • Ex: why is it as'paragus • but not ('aspa)('ragus) • 'gus' is extrametrical --> poor thing gets a degenerate foot (exhaustivity) • Tree construction is right to left and trochaic: • * • * * * * * * * < * > * (* *)< * > • asparagus => aspara<gus> => as('para)(gus) • More examples: ('visi)('bili)ty, re('peti)tive,
The future of metrical phonology • Can regularities be accounted for by transformational rules or by output constraints? • How does prominence in syllables affect stress in syllables? • Research in languages with ternary rhythm.
