tipa v1.0.14
tipa
tipa is a TypeScript package supporting parsing of linguistic input in Unicode, HTML Entity, and Branner (1994) formats. It contains extensive features from Hayes (2009) and Riggle (2012), allowing you to transform sounds reliably.
const tipa = require("tipa")
tipa.get("t") === tipa.devoice(tipa.get("d")) // true
const word = tipa.parse("liŋˈɡwɪ.stɪks")
const nucleus = word[0].nucleus[0].name // high front tense unrounded vowelInstallation
For Yarn:
$ yarn add tipaFor NPM:
$ npm install tipaFunctions

parse | string => word | parse("liŋˈɡwɪ.stɪks") |
get | string => ipa_symbol | get("low back rounded vowel") |
tokenize | string => ipa_symbol[] | tokenize(".ʕe.es.a.án.") |
collapse | ipa_symbol[] => ipa_segment[] | collapse(tokenize("kætz̥")) |
syllabify | ipa_segment[] => word | syllabify(collapse(tokenize("lu.nə"))) |
devoice | phone => phone | devoice(get("g")) |
Types
| Type | Meaning |
|---|---|
ipa_symbol | Base type which includes ipa_diacritic, ipa_suprasegmental, and ipa_letter. |
ipa_diacritic | Sub-type of ipa_symbol. Used to modify an ipa_letter in some way. Includes tone diacritics (1 - 5), secondary articulation, and length diacritics (long, half long, and extra short). |
ipa_suprasegmental | Sub-type of ipa_symbol. Used to create syllable boundaries and/or provide syllable-level information such as primary or secondary stress. |
ipa_letter | Sub-type of ipa_symbol. Can either be a vowel or consonant. Has a feature matrix defined by Hayes (2009). |
phone | A single, standalone sound. Can be an ipa_letter (e.g. [p]) or an ipa_letter followed by diacritics (e.g. [v̥̄]). |
ipa_segment | The building block of syllables. Can be a phone or a suprasegmental. |
syllable | A group of ipa_segments and the building block of words. Has an onset, nucleus, and coda, as well as a list of all constituent segments. |
word | A group of syllables and the end result of parsing. |
