Introduction

Features include:

• Query based on features. E.g., {fricative}
• Custom phone classes. E.g., \c, \v, \w (consonants, vowels, consonant or vowel respectively.)
• Query based on constituent type. E.g., {fricative}:C (fricative codas)
• Query based on stress. E.g., \c!1 (stressed consonants)
• Query based on tone. E.g., \v:tn("214") (vowel with tone 214)
• Aligned phonex for comparing IPA Target vs IPA Actual transcriptions
• Comments for annotating complex expressions

Note: An understanding of regular expressions (or regex) is useful for understanding phonex. Many online regular expression tutorials and guides are available for reference.

The || operator combines results from independent expressions. Each expression is evaluated separately against the input, and all matches from all expressions are returned together.

(\c)$ || (?<\v)(\c)(?>\v)

This finds consonants that are either word-final or intervocalic. Each side of || runs as a separate pattern; the results are unioned.

Unlike alternation (|) inside a group, || produces separate match results for each expression. Use || when you need to combine independent queries that cannot be expressed as a single pattern.

• Phone Matchers — character, feature, regex, and class matchers
• Quantifiers — greedy, reluctant, and possessive
• Groups — capture, named, lookahead/behind, back references
• Supplementary Matchers — stress, syllable type, diacritics, tone
• Syllable Matcher — the sigma (σ) matcher
• Aligned Phonex — alignment operator, deletions, deferred matching
• Phonex Constructs — complete single-page reference table
