Fatal error: Uncaught DomainException: Could not load the default credentials. Browse to https://developers.google.com/accounts/docs/application-default-credentials for more information in /jet/app/www/default/speech/vendor/google/auth/src/ApplicationDefaultCredentials.php:156 Stack trace: #0 /jet/app/www/default/speech/vendor/google/gax/src/CredentialsWrapper.php(197): Google\Auth\ApplicationDefaultCredentials::getCredentials(Array, Object(Google\Auth\HttpHandler\Guzzle6HttpHandler), NULL, NULL) #1 /jet/app/www/default/speech/vendor/google/gax/src/CredentialsWrapper.php(114): Google\ApiCore\CredentialsWrapper::buildApplicationDefaultCredentials(Array, Object(Google\Auth\HttpHandler\Guzzle6HttpHandler)) #2 /jet/app/www/default/speech/vendor/google/gax/src/GapicClientTrait.php(326): Google\ApiCore\CredentialsWrapper::build(Array) #3 /jet/app/www/default/speech/vendor/google/gax/src/GapicClientTrait.php(308): Google\Cloud\Speech\V1\Gapic\SpeechGapicClient->createCredentialsWrapper(NULL, Array) #4 /jet/app/www/default/speech in /jet/app/www/default/speech/vendor/google/gax/src/CredentialsWrapper.php on line 200

You need to secify env variable GOOGLE_APPLICATION_CREDENTIALS for service account key, see the link in the warning — Maksim
I have already did that And its working fine in command line while i run file through coomand line "php speech.php" it will working and executing result as expected but while same file run into browser it gives me above error — bhavyesh dhaduk
Try to var_dump(getenv('GOOGLE_APPLICATION_CREDENTIALS')); in browser. Next - try to chown www-data:www-data to key file. — Maksim

put it to manual

putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account-credentials.json');
