  4. default: Best for audio that is not one of the specific audio models.

You can set model in following way
$operation = $speech->beginRecognizeOperation(
   'gs://product_id/file_name.wav',
    array('model'=>'video')
);

You can get the punctuation in transcription results by providing enableWordTimeOffsets=true in the config.

for example:
You can set enableWordTimeOffsets in following way
$operation = $speech->beginRecognizeOperation(
   'gs://product_id/file_name.wav',
    array('enableWordTimeOffsets'=>true,'model'=>'video')
); 



Question: What is office link for speech to text?
https://cloud.google.com/speech-to-text/


Question: What is Github link for speech to text?
https://github.com/GoogleCloudPlatform/google-cloud-php-speech


Question: How to install the SDK for speech to text?
php composer.phar require google/cloud-speech



Question: How to get the transcription for small audio file.?
$audioFilePath='gs://ar10w12018/1135-19114_720p.wav';//You can place your path here
$speech = new SpeechClient([
    'languageCode' => 'en-US'
]);

// Recognize the speech in an audio file.
$results = $speech->recognize(
   $audioFilePath,
);

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



Question: How to get the transcription for heavy audio file.?
for heavy files, make sure you have already uploaded to google cloud and you have path.

$audioFilePath='gs://ar10w12018/1135-19114_720p.wav';//You can place your path here
$speech = new SpeechClient([
    'languageCode' => 'en-US'
]);

// Recognize the speech in an audio file.
$operation = $speech->beginRecognizeOperation(
   $audioFilePath,
    array('enableWordTimeOffsets'=>true,'model'=>'video')
); 
echo $operation->name(); //operation name

You can get the results by using Operation Name.
$operationName='194790781308823479';
$speech = new SpeechClient([
    'languageCode' => 'en-US'
]);
$operation = $speech->operation($operationName);

$isComplete = $operation->isComplete();
if($isComplete){
$results=$operation->results();

How to upload files to Google Cloud with PHP?

Question: What are different ways to access Google Services?
  1. Using Client Libraries like PHP, Node, Java etc
  2. Using Gcloud tool command line tool, in this you need to download the cloud SDK which is available for windows, mac and linux.

Question: Question: How to start with client libraries?
  1. Set up a "GCP Console project" (Skip, if already done).
    https://cloud.google.com/resource-manager/docs/creating-managing-projects
    Create or select a project.
    Enable the Google Speech-to-Text API for that project.
    Create a service account.
    Download a private key as JSON (Important, we need this).
  2. Set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the private key JSON file that contains your service account key(which you have downloaded)
  3. Install the client library
