这个Laravel\Lumen扩展包使用百度云语音识别API，提供一个简单的方法从语音文件中提取文本。代码基于官方php sdk构建。

使用前，请先前往百度AI开放平台，找到人工智能下的百度语音，创建应用。 百度的语言识别api是免费的，默认有50000/天的调用限制，需要的话可以申请提高配额到1000000/天。

由于百度的api只接受特定码率的文件，所以代码中使用ffmepg进行了转码。 所以有个需要注意的地方：

• 本地必须安装ffmepg
• PHP必须有shell_exec执行权限

To use this package, you should go to , find 人工智能->百度语音 and create a applicaton,then get the AppID, API Key, and Secret Key。

Require this package with composer by using the following command:

$ composer require pinkong/baidu-speech-recognition

Then, add the service provider:

If you are using Laravel, add the service provider to the providers array in config/app.php:

[
    'providers' => [
        Pinkong\BaiduSpeechRecognition\BaiduSpeechServiceProvider::class,
    ],
]

as optional, you can use facade:

    'aliases' => [
        'SpeechHelper' => Pinkong\BaiduSpeechRecognition\SpeechHelper::class,
    ],

If you are using Lumen, append the following code to bootstrap/app.php:

$app->register(Pinkong\BaiduSpeechRecognition\BaiduSpeechServiceProvider::class);

The defaults are set in config/baiduspeech.php. Copy this file to your own config directory to modify the values. You can publish the config using this command:

php artisan vendor:publish --provider="Pinkong\BaiduSpeechRecognition\BaiduSpeechServiceProvider"

If you are using Lumen, append the following code to bootstrap/app.php:

$app->configure('baiduspeech');

$result = SpeechHelper::convertMp3FileToPCM('test4.mp3');
