Node.js idiomatic client for Cloud Text-to-Speech API.
The Cloud Text-to-Speech API converts text or Speech Synthesis Markup Language (SSML) input into audio data of natural human speech.
Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

Select or create a Cloud Platform project.
Enable billing for your project.
Enable the Google Cloud Text-to-Speech API.
Set up authentication with a service account so you can access the API from your local workstation.
npm install --save @google-cloud/text-to-speech
t fs = require('fs');
mports the Google Cloud client library
t textToSpeech = require('@google-cloud/text-to-speech');
reates a client
t client = new textToSpeech.TextToSpeechClient();
he text to synthesize
t text = 'Hello, world!';
onstruct the request
t request = {
put: {text: text},
Select the language and SSML Voice Gender (optional)
ice: {languageCode: 'en-US', ssmlGender: 'NEUTRAL'},
Select the type of audio encoding
dioConfig: {audioEncoding: 'MP3'},
erforms the Text-to-Speech request
nt.synthesizeSpeech(request, (err, response) => {
(err) {
console.error('ERROR:', err);
return;
Write the binary audio content to a local file
.writeFile('output.mp3', response.audioContent, 'binary', err => {
if (err) {
console.error('ERROR:', err);
return;
}
console.log('Audio content written to file: output.mp3');
;
