Lecture 4 The Syllable
Syllables • Words consist of a Consonant followed by a Vowel. • Distortion of adult speech by children is common and typical. • However, this distortion obeys certain unwritten and unconscious laws. • These laws govern the way segments are abstractly connected in clusters known as Syllables. • Segments that are not consistent with these laws are not pronounced.
The Core Syllable • The core syllable is made up of a Nucleus preceded by an Onset: O(nset) N(ucleus) C V
The Core Syllable • Some languages only have CV syllables. • More commonly, languages allow for syllables of greater complexity. • The core syllable is, however, found in every language. • The fact that CV syllables are cross-linguistically attested offers an interesting parallel with their invariable occurrence in early child language.
Sonority and the Syllable • What motivates the CV configuration? • Some sounds are more sonorous than others. • Vowels have more sonority than consonants. • Therefore, sonority goes up from the onset to the nucleus.
The Coda • Syllable structure can be considerably richer than CV. • The segmental string that makes up a word like // ‘captain’ does not fit into the core syllable’s template. O N O N
The Coda • Segments that are not affiliated to a syllable fail to be pronounced. • Syllables act as licensers of phonetic material. • Therefore, /p/ and /n/ must be part of a syllable, as both are pronounced in the English word ‘captain’.
The Coda • Syllable structure in English admits more segmental material than the core syllable. • This is licensed through the Coda. O N Cd O N Cd
The Rime • Consider the following: A B C [] pat [] pat [] pat [b] bat [] pan [I] pit [k] cat [] pad [] pot [f] fat [] pack [] put • The three groups exhibit the same amount of phonetic overlap: [] in A, [] in B, and [ … ] in C. • However, ONLY the ones in group A rhyme with each other.
The Rime • Rhyming is not just a matter of overlap. • The overlap must affect a certain position within the syllable: N + Cd. • The nucleus and the coda group together in a constituent called Rime (R): O R N Cd
Basic Syllable Typology • The nucleus is essential to the syllable. • Onsets and codas are optional. • So, the basic syllable types are: ON ONCd NCd N • The core syllable template can undergo a number of changes: - delete the onset ON N C / _____ V CV V - insert a coda ON ONCd C / V _____ CV CVC - delete the onset ON NCd and insert a coda C / _____ V C / V _____ CV VC
Complexity • The core syllable CV is the simplest. - No operations • The VC is the most complex. - Both operations (deletion & insertion) • The V and CVC have intermediate complexity. - One operation (deletion OR insertion)

Complexity • Children acquire simpler syllable types before the more complex ones. • The presence of a more complex type in any one language presupposes the presence of its simpler counterpart(s). • Syllable-related historical change tends to go in the direction of greater syllable simplicity. • In languages with a rich range of syllable patterns, simpler syllables are more frequent in syllable inventories and in language use.
Complex Nuclei • Consider the following: O R O R N Cd N Cd i • The two words have the same syllable structure (ONCd). • However, do they fit the same syllable template (CVC)?
Complex Nuclei • Syllable structure is built on the timing tier, not on the melody tier: O R O R O R N Cd N Cd N Cd x x x x x x x x x x x i b a t beat bit bite CV:C CVC CVVC
Complex Onsets • To accommodate words like flag, glad, dress, and the like, the representation must allow for onsets with two timing slots: O R N Cd x x x x flag CCVC
More on Sonority • A syllable is made up of a segment of high sonority flanked by segments of lower sonority. • A syllable is a Cluster of Sonority, defined by a sonority peak. • And, speech is a sequence of such sonority clusters.
Branching Onsets in English • Bi-consonantal Onset Clusters: [pl] plain [] pray [bl] bless [b] bread [fl] fly [f] frame [] three [t] tree [d] dream [sl] sleep [S] shrub [kl] clean [k] cream [gl] glass [g] green
Branching Onsets in English • The first timing slot is filled with an obstruent. • The second timing slot is filled with a liquid. • The opposite order is never attested. • Why?
Conditioned Templates • The obstruent + liquid clusters can be formalized by imposing it into syllable templates: O R N Ob Lq
Sonority Hierarchy • A more plausible account, however, is offered by the “Sonority Hierarchy”: 4 Vowels Most Sonorous 3 Liquids 2 Nasals 1 Obstruents Least Sonorous • The Syllable Sonority Profile: i - rises ii - reaches a peak iii - falls
Sonority Sequencing • The sonority profile of the syllable is regulated by a universal principle: The Sonority Sequencing The sonority profile of the syllable must rise until it peaks, and then fall. • So, an onset such as ls, the converse of existing sl, would violate the Sonority Sequencing Principle.
Gaps • Although they are consistent with the Sonority Sequencing, (stop + fricative) or (stop + nasal) clusters do not occur in English onsets. • Is their absence from English arbitrary?
Sonority Distance • Sonority Distance may vary: (stop + fricative) 1 - 1 = 0 (stop + nasal) 2 - 1 = 1 (stop + liquid) 3 - 1 = 2 • In many languages, the segments of complex subsyllabic constituents need to satisfy a minimum of sonority distance. • This requirement is formalized through the Minimal Sonority Distance parameter. • For English, this parameter is set as follows: Minimal Sonority Distance in English Onsets The minimal sonority distance between the two elements of an English complex onset is 2.
Summing up • Syllables are abstract structures which cannot themselves be pronounced. • Children’s utterances consist principally of CV syllables. • There are no languages where CV syllables are not attested. • Syllable structure is richer than the core syllable. • Syllable complexity can be measured against the optimal CV configuration. • Syllable structure is built on the timing tier. • The distribution of vowels and consonants within a syllable is a consequence of sonority differences between these two classes of sounds. • The constraints on possible branching onsets in English are also explained by the principle of Sonority Sequencing and the Minimal Sonority Distance.
