It gives meError creating resource: [message] fopen(): php_network_getaddresses: getaddrinfo failed: Name or service not known [file] /Desktop/php_projects/text_speech/vendor/guzzlehttp/guzzle/src/Handler/StreamHandler.php [line] 323 [message] fopen(https://oauth2.googleapis.com/token): failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known [file] /Desktop/php_projects/text_speech/vendor/guzzlehttp/guzzle/src/Handler/StreamHandler.php [line] 323

It gives me error where on this line


$response = $client->synthesizeSpeech($synthesisInputText, $voice, $audioConfig);

$client = new TextToSpeechClient([
    'credentials' => ('/Documents/gcp_credentials/config.json')
]);

$synthesisInputText = (new SynthesisInput())
    ->setText('Hello, world! This is just for testing purpose.Lorem Ipsum is simply dummy text of the printing and typesetting industry.This is just for testing purpose.Lorem Ipsum is simply dummy text of the printing and typesetting industry');

$voice = (new VoiceSelectionParams())
    ->setLanguageCode('en-IN')
    ->setName('en-IN-Wavenet-A')
    ->setSsmlGender(SsmlVoiceGender::FEMALE);

$effectsProfileId = "telephony-class-application";

$audioConfig = (new AudioConfig())
    ->setAudioEncoding(AudioEncoding::LINEAR16)
    ->setEffectsProfileId(array($effectsProfileId));

$response = $client->synthesizeSpeech($synthesisInputText, $voice, $audioConfig);
$audioContent = $response->getAudioContent();

file_put_contents('output.wav', $audioContent);

I want to output the result error free every time I run this code.
