node-google-tts-api

Simple node.js library for google text to speech service

Installation

npm i node-google-tts-api 

Usage

const googleTTS = require('node-google-tts-api');
const tts = new googleTTS();
 
const fs = require('fs');
 
tts.get({
  text: "hello world",
  lang: "en"
}).then(data => {
  // returns mp3 audio src buffer
  fs.writeFileSync("./audio.mp3", data);
});

Text length limit

Google forbids sending text over 200 characters - which is not very cool. Therefore, a bypass was made:

tts.get({
  text: "a".repeat(200) + "b".repeat(50),
  lang: "en",
  limit_bypass: true // required parameter
}).then(arr => {
  // returns array with mp3 audio src buffers
  let data = tts.concat(arr); // concat audio files
  fs.writeFileSync("./audio.mp3", data);
});
