Google Cloud Speech for PHP

Idiomatic PHP client for Cloud Speech.

Latest Stable Version Packagist

NOTE: This repository is part of Google Cloud PHP. Any support requests, bug reports, or development contributions should be directed to that project.

Enables easy integration of Google speech recognition technologies into developer applications. Send audio and receive a text transcription from the Speech-to-Text API service.


To begin, install the preferred dependency manager for PHP, Composer.

Now to install just this component:

$ composer require google/cloud-speech

Or to install the entire suite of components at once:

$ composer require google/cloud

This component supports both REST over HTTP/1.1 and gRPC. In order to take advantage of the benefits offered by gRPC (such as streaming methods) please see our gRPC installation guide.


Please see our Authentication guide for more information on authenticating your client. Once authenticated, you'll be ready to start making requests.


require 'vendor/autoload.php';

use Google\Cloud\Speech\SpeechClient;

$speech = new SpeechClient([
    'languageCode' => 'en-US'

// Recognize the speech in an audio file.
$results = $speech->recognize(
    fopen(__DIR__ . '/audio_sample.flac', 'r')

foreach ($results as $result) {
    echo $result->topAlternative()['transcript'] . "\n";


This component is considered alpha. As such, it is still a work-in-progress and is more likely to get backwards-incompatible updates.

Next Steps

  1. Understand the official documentation.
  2. Take a look at in-depth usage samples.
