Speak To Me - Mozilla Speech Recognition API

Node.js module for SpeakToMe, Mozilla's Speech-to-text REST API.

Supports recording of audio on local system, encoding and sending the recording to Mozilla's service for processing, and retrieval of results.

Installation

Support for recording from system or USB mics is through the mic package, which depends on installation OS-specific recording utilities:

Windows and Mac OS X require SOX and Linux requires ALSA tools.

• Windows: Download and install SOX from the website

• Linux: sudo apt-get install alsa-base alsa-utils

• Mac OS X: brew install sox

Install via npm:

 
npm install speaktome-node

Usage

var speech = require('speaktome-node');
 
speech.record().then(results => {
 
  // Results is an array of objects containing
  // `text` and `confidence` properties:
  //
  // [
  //   { confidence: "0.8090", text: "TEST" }
  // ]
  console.log(results);
 
}).catch(console.error);
