Syllable Structure Type Lookup (CV/CVC)

Audit explicitly annotated observed syllable onset/nucleus/coda patterns, retaining diphthong VV nuclei and actual inventory; no phonetic segmentation or language-wide permissible template inference.

Description

A syllable pattern records onset, nucleus and coda under a caller’s segmentation.

A syllable pattern records onset, nucleus and coda under a caller’s segmentation. Multiple V symbols may represent a multi-vowel nucleus.^[1]

Enter nonempty uppercase patterns of at most32 characters matching C*V+C*. Return distinct patterns in first-occurrence order, per-record counts and binary open-syllable flags.

When to use Syllable Structure Type Lookup (CV/CVC)

Use Syllable Structure Type Lookup (CV/CVC) when you need to evaluate the supplied records under the calculation and evidence rules below. No sound segmentation or language-wide permissible syllable inventory is inferred.

Prepare explicit text tokens, annotated language observations, caller mappings or a supported locale as requested. Preserve source evidence and the stated Unicode counting convention.

How to use Syllable Structure Type Lookup (CV/CVC) and understand its results

Prepare explicit text tokens, annotated language observations, caller mappings or a supported locale as requested. Preserve source evidence and the stated Unicode counting convention.
Enter callerAnnotatedSyllablePatterns using the field table and calculation rules, then run the tool.
Read distinctObservedSyllablePatterns, onsetConsonantCounts, codaConsonantCounts, openSyllableFlags. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
callerAnnotatedSyllablePatterns	Caller annotated syllable patterns	list of string	Required

Enter nonempty uppercase patterns of at most32 characters matching C*V+C*. Return distinct patterns in first-occurrence order, per-record counts and binary open-syllable flags.

onset=characters before first V; coda=after last V

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
distinctObservedSyllablePatterns	Distinct observed syllable patterns	list of string
onsetConsonantCounts	Onset consonant counts	list of number
codaConsonantCounts	Coda consonant counts	list of number
openSyllableFlags	Open syllable flags	list of number

Limitations and assumptions

No sound segmentation or language-wide permissible syllable inventory is inferred.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Word Order Typology SOV/SVO/VSO Lookup: Word-order labels describe annotated subject, verb and object positions in a clause. One clause is not a language’s dominant typology. For a complementary task, use Stress-Timed vs Syllable-Timed Classifier: Rhythm metrics summarize measured interval variability. They do not by themselves establish stress timing, syllable timing or isochrony.
