@google-cloud/speech
Advanced tools
The Cloud Speech API enables easy integration of Google speech recognition technologies into developer applications. Send audio and receive a text transcription from the Cloud Speech API service.
Set up authentication with a service account so you can access the API from your local workstation.
Install the client library:
npm install --save @google-cloud/speech
Try an example:
// 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
client
.recognize(request)
.then(data => {
const response = data[0];
const transcription = response.results
.map(result => result.alternatives[0].transcript)
.join('\n');
console.log(`Transcription: ${transcription}`);
})
.catch(err => {
console.error('ERROR:', err);
});
Samples are in the samples/

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.
