Using Google Speech Recognition API with PHP - php

Question

I want to make a simple script that uses google speech recognition, I have tried various ways so that I can access the API with Request Body, but has always failed.
Example URL: https://content-speech.googleapis.com/v1/speech:recognize?prettyPrint=true&alt=json&key=AIzaSyD-XXXXXXXXXXXXXXXXX-Al7hLQDbugrDcw
JSON example:
{
"audio": {
"content": "ZkxhQwAAACIEg....more......FzSi6SngVApeE="
},
"config": {
"encoding": "FLAC",
"sampleRateHertz": 16000,
"languageCode": "en-US"
}
}

Documentation:

Code samples:
https://cloud.google.com/speech-to-text/docs/samples
Consider using a library:
Google Cloud Client Library PHP (also has code samples):
https://googlecloudplatform.github.io/google-cloud-php/#/docs/google-cloud/v0.61.0/speech/speechclient
Speech-to-Text Client Libraries
https://cloud.google.com/speech-to-text/docs/reference/libraries#client-libraries-install-php
Speaker is a 3.party library you could use:

Quick example from google/cloud-speech:
Install:
composer require google/cloud-speech
Sample:
# Includes the autoloader for libraries installed with composer
require __DIR__ . '/vendor/autoload.php';
# Imports the Google Cloud client library
use Google\Cloud\Speech\SpeechClient;
# Your Google Cloud Platform project ID
$projectId = 'YOUR_PROJECT_ID';
# Instantiates a client
$speech = new SpeechClient([
'projectId' => $projectId,
'languageCode' => 'en-US',
]);
# The name of the audio file to transcribe
$fileName = __DIR__ . '/resources/audio.raw';
# The audio file's encoding and sample rate
$options = [
'encoding' => 'LINEAR16',
'sampleRateHertz' => 16000,
];
# Detects speech in the audio file
$results = $speech->recognize(fopen($fileName, 'r'), $options);
foreach ($results as $result) {
echo 'Transcription: ' . $result->alternatives()[0]['transcript'] . PHP_EOL;
}
