Quickstart

Before you begin

1. Select or create a Cloud Platform project.

   Go to the projects page

2. Enable billing for your project.

   Enable billing

3. Enable the Google Cloud Speech API API.

   Enable the API

4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install --save @google-cloud/speech

Using the client library

mports the Google Cloud client library
t speech = require('@google-cloud/speech');
t fs = require('fs');

reates a client
t client = new speech.SpeechClient();

he name of the audio file to transcribe
t fileName = './resources/audio.raw';

eads a local audio file and converts it to base64
t file = fs.readFileSync(fileName);
t audioBytes = file.toString('base64');

he audio file's encoding, sample rate in hertz, and BCP-47 language code
t audio = {
ntent: audioBytes,

t config = {
coding: 'LINEAR16',
mpleRateHertz: 16000,
nguageCode: 'en-US',

t request = {
dio: audio,
nfig: config,


etects speech in the audio file
nt
ecognize(request)
hen(data => {
const response = data[0];
const transcription = response.results
  .map(result => result.alternatives[0].transcript)
  .join('\n');
console.log(`Transcription: ${transcription}`);

atch(err => {
console.error('ERROR:', err);
;

Samples

Samples are in the samples/ directory. The samples' README.md has instructions for running the samples.

| Sample | Source Code | Try it | | ————————— | ——————————— | —— | | Speech Recognition | source code | | | Speech Recognition v1p1beta1 | source code | |

The Speech API Node.js Client API Reference documentation also contains samples.

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.
