gTTS.js

gTTS.js (Google Text to Speech): a ported version of gTTS python library which is a interface to Google's Text to Speech API. Create an mp3 file with the gTTS module or gtts-cli command line utility. It allows for unlimited lengths of spoken text by tokenizing long sentences where the speech would naturally pause.

Install

npm install gtts

How to use

Use save method

const gTTS = require('gtts');
var gtts = new gTTS('text to speak', 'en');
gtts.save('/tmp/hello.mp3', function (err, result) {
  if(err) { throw new Error(err) }
  console.log('Success! Open file /tmp/hello.mp3 to hear result.');
});

Use stream method

const express = require('express');
const app = express();
const Gtts = require('gtts');

app.get('/hear', function (req, res) {
  const gtts = new Gtts(req.query.text, req.query.lang);
  gtts.stream().pipe(res);
});

app.listen(3000, function () {
  console.log('Open url to hear Hallelujah http://localhost:3000/hear?lang=en&text=Hallelujah');
});
