我是使用 google API 的新手。我正在尝试使用谷歌语音识别，将我的语音转换为文本，反之亦然。但不知道如何使用谷歌语音API。我使用这个命令下载了谷歌云包

composer require google/cloud

但我不知道如何使用它。我正在关注此链接中的教程https://github.com/GoogleCloudPlatform/google-cloud-php。但它向我展示了错误。

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

首先，看起来您需要生成服务帐户凭据:)。

请查看本指南以进行设置：https ://googlecloudplatform.github.io/google-cloud-php/#/docs/latest/guides/authentication

从那里您将要执行以下操作：

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();
