如何使用 Amazon Polly 自动播放 MP3

如何解决如何使用 Amazon Polly 自动播放 MP3

我正在为文本转语音实施 Amazon Polly。我能够成功生成一个 mp3 文件，但我希望该 mp3 播放能够自动播放。请告诉我应该在代码中添加什么来添加此功能。所以，当我点击按钮时，它应该开始说出文本框中的内容。

这是我的代码：

<?PHP
require 'vendor/autoload.PHP';

use Aws\Polly\PollyClient;

if ( isset($_POST['file']) ) {

    try {
        $config = [
            'version' => 'latest','region' => 'us-west-1','credentials' => [
                'key' => '***','secret' => '***',]
            ];

        $client = new PollyClient($config);

        $val = $_POST['file'];

        $args = [
            'OutputFormat' => 'mp3','Text' => $val,//'TextType' => 'text','VoiceId' => 'Matthew',//pass preferred voice id here
        ];

        $result = $client->synthesizeSpeech($args);

        $resultData = $result->get('AudioStream');//->getContents();

        /*header('Content-length: ' . strlen($resultData));
        header('Content-disposition: attachment; filename="text-to-speech.mp3"');
        header('X-Pad: avoid browser bug');
        header('Cache-Control: no-cache');*/

        $myfile = fopen("test.mp3","w");
        fwrite($myfile,$resultData);
        fclose($myfile);

        echo 'test.mp3';//$resultData;

    } catch(Exception $e) {
        echo $e->getMessage();
    }
}
?>
