Quickstart
Before you begin
- Select or create a Cloud Platform project.
- Enable the Cloud 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/speech
Using the client library
async function main() {
// Imports the Google Cloud client library
const speech = require('@google-cloud/speech');
const fs = require('fs');
// Creates a client
const client = new speech.SpeechClient();
// The name of the audio file to transcribe
const fileName = './resources/audio.raw';
// Reads a local audio file and converts it to base64
const file = fs.readFileSync(fileName);
const audioBytes = file.toString('base64');
// The audio file's encoding, sample rate in hertz, and BCP-47 language code
const audio = {
content: audioBytes,
};
const config = {
encoding: 'LINEAR16',
sampleRateHertz: 16000,
languageCode: 'en-US',
};
const request = {
audio: audio,
config: config,
};
// Detects speech in the audio file
const [response] = await client.recognize(request);
const transcription = response.results
.map(result => result.alternatives[0].transcript)
.join('\n');
console.log(`Transcription: ${transcription}`);
}
main().catch(console.error);

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.
