PHP implementation of the Google Speech to Text API

PHP Speech To Text

About

This is an example file to demonstrate how to interact with the Google Speech API.

Getting Started

Visit: https://code.google.com/apis/console/ Enable the Speech API listed on the page.

Don't see Speech API?

That's a fairly common thing. It seems that only developers on the chromium-dev list actually can see it listed.

Don't worry. Go to: http://groups.google.com/a/chromium.org/group/chromium-dev/topics

Now, sign up for the list.

Go back to the API Console and refresh the page. You'll see it listed.

Usage

See the sample/example.php file, or use this below:

<?php
include 'GoogleSpeechToText.php';

// Your API Key goes here.
$apiKey = '';
$speech = new GoogleSpeechToText($apiKey);
$file = realpath(__DIR__ . '/quick.flac'); // Full path to the file.
$bitRate = 44100; // The bit rate of the file.
$result = $speech->process($file, $bitRate, 'en-US');
var_dump($result);

Running the example file outputs:
