Build Status

This simply uses the eSpeak cli program to generate wav audio data from text strings. You can then use the raw binary data to output to a file, send as a http download, get as a base64-encoded data URI string, or whatever else.

Install

$ npm install espeak

Usage

var espeak = require('espeak');

// optionally set the path to the `espeak` cli program if it's not in your PATH
//espeak.cmd = '/usr/bin/espeak';

espeak.speak('hello world', function(err, wav) {
  if (err) return console.error(err);

  // get the raw binary wav data
  var buffer = wav.buffer;

  // get a base64-encoded data URI
  var dataUri = wav.toDataUri();
});

// optionally add custom cli arguments for things such as pitch, speed, wordgap, etc.
espeak.speak('hello world, slower', ['-p 60', '-s 90', '-g 30'], function(err, wav) {});

There are some related modules, although there seems to be some scattered forks and it wasn't clear to the author which was updated and/or compatible with Node.js/npm at the time of writing this.

npm loves you
