About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

CMUdict

The Carnegie Mellon Pronouncing Dictionary.

The Carnegie Mellon University Pronouncing Dictionary (CMUDict), created by the Speech Group in the School of Computer Science at CMU, is "an open-source machine-readable pronunciation dictionary for North American English that contains over 134,000 words".

Installation

npm install @stdlib/datasets-cmudict

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch (see README).
• If you are using Deno, visit the deno branch (see README for usage intructions).
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch (see README).
• To use as a general utility for the command line, install the corresponding CLI package globally.

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

Usage

var cmudict = require( '@stdlib/datasets-cmudict' );

cmudict( [options] )

Returns datasets from the Carnegie Mellon Pronouncing Dictionary (CMUdict).

var data = cmudict();
/* returns
    {
        'dict': {...},
        'phones': {...},
        'symbols': [...],
        'vp': {...}
    }
*/

The function accepts the following options:

• data: dataset name. The following names are recognized:

  • dict: the main pronouncing dictionary
  • phones: manners of articulation for each sound
  • symbols: complete list of ARPABET symbols used by the dictionary
  • vp: verbal pronunciations of punctuation marks

To only return the main pronouncing dictionary, set the data option to dict.

var opts = {
    'data': 'dict'
};

var data = cmudict( opts );
/* returns
    {
        'A': 'AH0',
        'A(1)': 'EY1',
        'A\'S': 'EY1 Z',
        // ...
    }
*/

To return only sound articulation manners, set the data option to phones.

var opts = {
    'data': 'phones'
};

var data = cmudict( opts );
/* returns
    {
        'AA': 'vowel',
        'AE': 'vowel',
        'AH': 'vowel',
        // ...
    }
*/

To return only ARPABET symbols used by the dictionary, set the data option to symbols.

var opts = {
    'data': 'symbols'
};

var data = cmudict( opts );
/* returns
    [
        'AA',
        'AA0',
        'AA1',
        // ...
    ]
*/

To return only the verbal pronunciations of punctuation marks, set the data option to vp.

var opts = {
    'data': 'vp'
};

var data = cmudict( opts );
/* returns
    {
        '!exclamation-point': 'EH2 K S K L AH0 M EY1 SH AH0 N P OY2 N T',
        '"close-quote': 'K L OW1 Z K W OW1 T',
        '"double-quote': 'D AH1 B AH0 L K W OW1 T',
        // ...
    }
*/

Notes

• Vowels carry a lexical stress marker (0: No stress, 1: Primary stress, 2: Secondary stress).
• The phoneme set is based on the ARPAbet symbol set developed for speech recognition.

Examples

var cmudict = require( '@stdlib/datasets-cmudict' );

var opts = {};

opts.data = 'phones';
console.dir( cmudict( opts ) );

opts.data = 'symbols';
console.dir( cmudict( opts ) );

opts.data = 'dict';
console.dir( cmudict( opts ) );

CLI

Installation

To use as a general utility, install the CLI package globally

npm install -g @stdlib/datasets-cmudict-cli

Usage

Usage: cmudict [options]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --data name           Dataset name: dict, phones, symbols, vp.

Notes

• If the --data option is set to a supported dataset name, the CLI prints the contents of the respective dataset file as plain text. Otherwise, the output format is newline-delimited JSON (NDJSON).

Examples

$ cmudict --data symbols
AA
AA0
AA1
AA2
...
