word-phoneme-map

Provides a two-way map between the words and phonemes listed in the CMU Pronouncing Dictionary. You can look up words that correspond to phoneme sequences and look up phoneme sequences that correspond to words.

Installation

npm install word-phoneme-map

Usage

Sometime before you use the map, you need to call setUpDatabase to set up a database, like so:

var setUpDatabase = require('word-phoneme-map').setUpDatabase;
setUpDatabase(
  {
    dbLocation: __dirname + '/where-you-want-it/a-word-phoneme.db'
  },
  done
);

function done(error) {
  if (error) {
    console.log(error)
  }
  else {
    console.log('Successfully set up database.');
  }
}

You only need to do this once.

From then on, you can use the map like this:

var createWordPhonemeMap = require('word-phoneme-map').createWordPhonemeMap;
var wordPhonemeMap = createWordPhonemeMap({
  dbLocation: __dirname + '/where-you-want-it-/a-word-phoneme.db'
});

wordPhonemeMap.wordsForPhonemeSequence(['AA', 'R', 'K'], showWords);

function showWords(error, words) {
  if (error) {
    console.log(error);
  }
  else {
    console.log(words);
  }
}

Output:

[
  'ARC',
  'ARK'
]

To do lookups in the opposite direction, do this:

wordPhonemeMap.phonemeSequencesForWord('ARK', showPhonemes);

function showPhonemes(error, phonemeSequences) {
  if (error) {
    console.log(error);
  }
  else {
    console.log(phonemeSequences);
  }
}

Output:

[
  ['AA', 'R', 'K']
]
