how to use google cloud speech API

Question

I am new to use the google API's. I am trying to use the google speech recognition, to convert my speech to text and vise versa. But don't know how to use the google speech API. I download the google cloud package using this command

composer require google/cloud

But I dont know how to use this. I am following tutorial https://github.com/GoogleCloudPlatform/google-cloud-php from this link. but it showing me errors.

Fatal error:  Uncaught Google\Cloud\Exception\ServiceException: Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information in /var/www/html/googlevoice/vendor/google/cloud/src/RequestWrapper.php:221

First things first it looks like you need to generate your service account credentials :).

Please take a look at this guide in order to get that set up: https://googlecloudplatform.github.io/google-cloud-php/#/docs/latest/guides/authentication

From there you'll want to do the following:

require 'vendor/autoload.php';

use Google\Cloud\Storage\StorageClient;

// Pass the key file directly into your client.
$storage = new StorageClient([
    'keyFilePath' => '/path/to/service/credentials.json'
]);

// OR

// Store the key file as an environment variable
putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service/credentials.json');

$storage = new StorageClient();
