Syllable Structure

From Categories to Structure: Phonological Representations

Linguistic Categories

  • Linguistic knowledge is composed of basic categories including:

    • Phonological features

    • Phonemes

  • Languages exhibit variation in phonemic categories:

    • Distinctive Sounds: Examples include:

    • English distinguishes between /l/ and /r/, while Korean does not.

    • Hindi contrasts /p/, /ph/, and /b/, while English only contrasts /p/ and /b/.

  • Each language may have unique phonemic inventories and distinctive phonological features.

Categories and Their Distributions

  • Not every phonetic category is utilized to its full potential in a language:

    • Minimal Pairs in English:

    • "rum" [m] vs. "run" [n] vs. "rung" [ŋ]

    • [ŋ] is absent at the beginning of words: e.g., *ngap.

  • Some phonemes have specific constraints in their distributions:

    • Consonant sequences such as [kɹ] or [skɹ] are acceptable in initial word positions but not at the end.

Phonotactic Constraints

  • Phonotactic constraints determine permissible phoneme sequences in a language.

  • These constraints require understanding the organization of phonemes into larger units called syllables.

The Syllable

  • Syllables form the basic units of spoken words, generally consisting of:

    • Nucleus: The central, energetic part of the syllable.

    • Onset: Sounds preceding the nucleus.

    • Coda: Sounds that follow the nucleus.

  • Examples of syllable counting:

    • "Canada" has 3 syllables and is trisyllabic: [kænǝdǝ].

    • "splint" has 1 syllable and is monosyllabic: [splInt].

  • Syllable structure varies across languages, affecting judgments of syllable counts.

Evidence from Speech Errors

  • Examples of speech errors help demonstrate syllable structures:

    • Exchange Errors: e.g., "speak fast" → "feak spast"

    • Perseveration Errors: e.g., "beef noodle" → "beef needle"

    • Anticipation Errors: e.g., "blot up" → "blop up"

  • Errors maintain syllable positions, often keeping nucleus and coda intact while changing other parts.

Evidence for the Rime

  • The rime consists of the nucleus and coda, exhibiting more complex constraints compared to onset:

    • e.g., /fl/ + vowel combinations are permissible while vowel + /lf/ ones are not.

  • Speech errors tend to impact the rime together:

    • Example: "spill beer" → "spill bill"

Syllable Structure Constraints

  • Different languages possess unique rules governing acceptable syllable constructions:

    • Some languages:

    • Allow optional onsets and codas (e.g., English).

    • Mandate onsets (e.g., Thai) or forbid codas (e.g., Hawaiian).

Assigning Syllable Structure

  • Basic algorithm for syllable assignment:

    1. σ-assignment: Assigning vowels to nucleus positions.

    2. Onset formation: Adding consonants to the onset as permissible.

    3. Coda formation: Consonants can be added to the coda following a nucleus.

  • Syllable patterns illustrated through examples:

    • Structure: For “ædamǝnt”, illustrate the mechanisms of onset and coda formation based on given sounds.

Phonotactics

  • Phonotactic rules specify that certain sounds can or cannot appear in specific syllable positions.

    • Example: “nt” is allowed as a coda but not as an onset in English.

  • Assignments must adhere to phonotactic constraints, affecting syllable formation.

Language-Specific Syllable Assignment Rules

  • Different languages employ varying rules resulting in different rankings of constraints:

    • Some might prioritize avoiding codas over onsets.

    • Syllable typologies and structures can be traced back to the way constraints are ranked conceptually.

Explaining Syllable Typology (Prince and Smolensky, 1993)

  • Optimality Theory: Determines well-formedness through constraint optimization:

    • Evolution of Candidates: All potential outputs generated by the GEN function (considering factors like epenthesis, deletion).

  • Constraints analysis:

    • Markedness constraints may include:

    • Onset: All syllables must have an onset.

    • NoCoda: Syllables should ideally have no coda.

  • Faithfulness constraints ensure that elements from the input are preserved in the output without deletion or extraneous addition.

Syllabification Process Examples

  • Several scenarios exemplify the outcomes of varying rankings of constraints:

    • Syllabification procedure shown with inputs demonstrating permissible outcomes based on constraints prioritized:

    • Outputs differ when constraints are altered indicating how grammatically feasible structures can be generated.

Language Typology

  • The possible forms in each language hinge on the specific rankings of a universal set of constraints:

    • Factorial Typology: Each constraint ranking yields distinct grammatical structures, establishing possibly divergent linguistic patterns and forms.

Ranking Examples

  1. Onset >> NoCoda >> Faith

  2. Onset >> Faith >> NoCoda

  3. Faith >> Onset >> NoCoda

  • These rankings examine the implications of syllable construction and permissible outputs according to the applied constraints.

Implicational Universals in Syllable Structures

  • Syllable structure demonstrates predictability based on constraints and typologies:

    • If a syllable contains a vowel (V), it must comprise a consonant and vowel (CV).

    • Presents a cascading hierarchy for syllable complexity: CV, CVC, CCV, etc.
