Demo

Basic Usage

 
var Speech = require('speech')
var recognizer = new Speech({
    lang: 'cmn-Hans-CN', // Mandarin Chinese, default is English.
    // all boolean options default to false
    debugging: true, // will console.log all results
    continuous: true, // will not stop after one sentence
    interimResults: true, // trigger events on iterim results
    autoRestart: true, // recommended when using continuous:true
                      // because the API sometimes stops itself
                      // possibly due to network error.
})
 
// simply listen to events
// chainable API
recognizer
    .on('start', function () {
        console.log('started')
    })
    .on('end', function () {
        console.log('ended')
    })
    .on('error', function (event) {
        console.log(event.error)
    })
    .on('interimResult', function (msg) {
        document.body.innerHTML = msg
    })
    .on('finalResult', function (msg) {
        document.body.innerHTML = msg
    })
    .start()
 

You can also access Chrome's native recognition object:

recognizer.recognition.continuous = false
