CV Pattern Match

The CV Pattern Match analysis converts each aligned IPA Target and IPA Actual word into a consonant-vowel pattern, compares the two patterns, and reports the percentage that match.

Use this analysis when the sequence of consonants, vowels, glides, stress, and optional syllable boundaries matters more than the identity of the phones.

Parameters

Table 1. CV Pattern Match parameters
Parameter	Default	Effect
Report Title	CV Pattern Match	Sets the title of the generated report.
Combine results for all selected participants	Off	Combines the selected participants before calculating summaries and pattern tables.
Ignore truncated	On	Excludes a result when its aligned IPA Actual word is empty.
CV Pattern Options: diacritics	Ignore diacritics except half-long and long	Removes other diacritics before constructing each pattern. The retained length marks can affect compensatory lengthening.
Include stress markers	On	Retains primary and secondary stress in the pattern.
Include explicit syllable boundaries (.)	On	Retains syllable boundaries explicitly present in the transcription.
Insert implicit (unmarked) syllable boundaries	Off	Adds boundaries between syllables when no boundary or stress marker is already present.
Compensatory lengthening	On	Represents a long or half-long consonant, glide, or vowel by doubling its CV-pattern symbol.
Simplify composed phones	On	Represents a phone joined by a tie bar with one CV-pattern symbol.

The underlying Aligned IPA Domains query searches by word with empty IPA Target and IPA Actual Phonex filters and adds the aligned Orthography word. Standard word, syllable, additional-tier-data, and participant filters can narrow or extend the results. See Common Query Parameters.

How patterns are compared

Each IPA word is covered with C for consonants, G for glides, and V for vowels. The selected stress, syllable-boundary, length, and composed-phone options are then applied. A result is a match only when the complete target and actual pattern strings are equal.

Word Count is the number of non-truncated aligned word pairs. Match % and Mismatch % divide their respective counts by Word Count and multiply by 100.

Report output

The report contains a global Summary, a Readme, and one section per participant:

Table 2. CV Pattern Match report tables
Table	Contents
Summary	One row per participant with Word Count, CV Matches, CV Match %, CV Mismatches, and CV Mismatch %. The participant section repeats these measures by session and includes age.
CV Patterns	Each target/actual pattern pair, whether it matched, its total frequency, and its percentage of the participant's results.
CV Matches and CV Mismatches	Token listings with source-record information, aligned IPA words, added tier data, word index, target and actual CV patterns, and the comparison result.

This comparison is also included in Word Match.
