The IPA Transliterator is a JavaScript library that translates text to the International Phonetic Alphabet (IPA) using a dictionary of words and a set of phonological rules. The library uses a trie data structure to efficiently search for words in the dictionary and apply phonological rules to the words. The library also supports pre and post processing of rules using custom rule processors.
Set a language
const language = 'en_UK'; Create a new instance of the TrieWordStepper class and load the dictionary for the language you want to translate:
const trieWord = new TrieWordStepper();
trieWord.loadDictionary(language);The TrieOrthographySteppers provide rules for generating phonetics where there may be gaps in an IPA dictionary
You can then create a new instance of the TrieOrthographyStepper class and add it as an orthography stepper to the TrieWordStepper instance:
const trieOrthography = new TrieOrthographyStepper();
trieOrthography.loadDictionary(language);
trieWord.addOrthographyStepper(trieOrthography);You can add custom rule processors to the TrieOrthographyStepper instance:
trieOrthography.addRulePreprocessor(language);
trieOrthography.addRulePostprocessor(language);Finally, you can translate a piece of text using the translateText method of the TrieWordStepper instance:
const text = 'Hello world!';
const result = trieWord.translateText(text);
console.log(result); // həˈloʊ wɔrld!The IPA Transliterator is released under the MIT License. See the LICENSE file for details.
The orthography stepper uses rules and processes heavily borrowed from Epitran https://github.com/dmort27/epitran
