# PocketSphinx for Node.js

This module aims to allow basic speech recognition on portable devices

through the use of PocketSphinx.

## Installation

Windows installation is not supported yet.

To build this module you need to have following dependencies:

  

  * node at least 4.2

  * cmake at least version 3.1

  * cmake-js https://github.com/cmake-js/cmake-js (install with `npm install -g cmake-js`) 

  * sphinxbase latest from github

  * pocketsphinx latest from github

  * swig at least 3.0.7

  * pkg-config

Make sure that pocketsphinx is installed properly, adjust LD_LIBRARY_PATH if libraries are not found. You can test pocketsphinx with

     pocketsphinx_continuous -infile goforward.raw // Recognize goforward.raw file

Make sure that PKG_CONFIG_PATH includes the folder where you installed pocketsphinx, for example, if you installed with default prefix, export PKG_CONFIG_PATH:

     export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

You can test installation with 

     pkg-config --modversion pocketsphinx // This should print the version

To build simply use npm install, it should detect everything automatically. Carefully read

build logs in order to see if there are any issues.

## Example

```javascript

var fs = require('fs');

var ps = require('pocketsphinx').ps;

modeldir = "../../pocketsphinx/model/en-us/"

var config = new ps.Decoder.defaultConfig();

config.setString("-hmm", modeldir + "en-us");

config.setString("-dict", modeldir + "cmudict-en-us.dict");

config.setString("-lm", modeldir + "en-us.lm.bin");

var decoder = new ps.Decoder(config);

fs.readFile("../../pocketsphinx/test/data/goforward.raw", function(err, data) {

    if (err) throw err;

    decoder.startUtt();

    decoder.processRaw(data, false, false);

    decoder.endUtt();

    console.log(decoder.hyp())

});

```
