Google Cloud Text-to-Speech: Node.js Client
Cloud Text-to-Speech API client for Node.js
A comprehensive list of changes in each version may be found in the CHANGELOG.
- Google Cloud Text-to-Speech Node.js Client API Reference
- Google Cloud Text-to-Speech Documentation

Quickstart
Before you begin
- 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.
Installing the client library
npm install @google-cloud/text-to-speech
Using the client library
// Imports the Google Cloud client library
const textToSpeech = require('@google-cloud/text-to-speech');
// Import other required libraries
const fs = require('fs');
const util = require('util');
// Creates a client
const client = new textToSpeech.TextToSpeechClient();
async function quickStart() {
// The text to synthesize
const text = 'hello, world!';
// Construct the request
const request = {
input: {text: text},
// Select the language and SSML voice gender (optional)
voice: {languageCode: 'en-US', ssmlGender: 'NEUTRAL'},
// select the type of audio encoding
audioConfig: {audioEncoding: 'MP3'},
};
// Performs the text-to-speech request
const [response] = await client.synthesizeSpeech(request);
// Write the binary audio content to a local file
const writeFile = util.promisify(fs.writeFile);
await writeFile('output.mp3', response.audioContent, 'binary');
console.log('Audio content written to file: output.mp3');
}
quickStart();
Samples
Samples are in the samples/
directory. Each sample's README.md
has instructions for running its sample.
Sample | Source Code | Try it |
---|---|---|
Audio Profile | source code | |
List Voices | source code | |
Quickstart | source code | |
Ssml Addresses | source code | |
Synthesize | source code |
The Google Cloud Text-to-Speech Node.js Client API Reference documentation also contains samples.
Supported Node.js Versions
Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.
Client libraries targeting some end-of-life versions of Node.js are available, and
can be installed via npm dist-tags.
The dist-tags follow the naming convention legacy-(version)
.
Legacy Node.js versions are supported as a best effort:
- Legacy versions will not be tested in continuous integration.
- Some security patches may not be able to be backported.
- Dependencies will not be kept up-to-date, and features will not be backported.
Legacy tags available
legacy-8
: install client libraries from this dist-tag for versions compatible with Node.js 8.
Versioning
This library follows Semantic Versioning.
This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
