使用PHP SDK语音反垃圾接口检测实时语音流或语音文件中的垃圾内容。

背景信息

语音流检测和语音文件检测均为异步检测，检测结果需要您以轮询或者回调的方式获取。关于调用请求中的检测场景参数scenes，返回结果中的分类参数label，以及操作建议参数suggestion的说明，请参见语音异步检测。

语音检测按照检测的语音文件、语音流的时间长度进行计费，计费粒度为分钟，每天累计检测总时长进行计量统计，每天检测总时长不足一分钟的按照一分钟进行计费。

准备工作

在进行具体的服务调用之前，请完成以下准备工作：
  • 创建阿里云AccessKey。关于阿里云AccessKey的具体操作，请参见创建AccessKey。
  • 安装PHP依赖。关于安装PHP依赖的具体操作，请参见安装PHP依赖。

提交语音异步检测任务

接口 描述 支持的地域
VoiceAsyncScanRequest 异步检测语音流或语音文件中是否包含违规内容。语音流格式支持：
  • RTMP
  • HTTP
  • FLV
 cn-shanghai：华东2（上海）
示例代码
  • 提交语音URL
    <?php

include_once 'aliyuncs/aliyun-php-sdk-core/Config.php';
use Green\Request\V20180509 as Green;

$iClientProfile = DefaultProfile::getProfile("cn-shanghai", "您自己的AccessKeyId", "您自己的AccessKeySecret");
DefaultProfile::addEndpoint("cn-shanghai", "cn-shanghai", "Green", "green.cn-shanghai.aliyuncs.com");
$client = new DefaultAcsClient($iClientProfile);
$request = new Green\VoiceAsyncScanRequest();
$request->setMethod("POST");
$request->setAcceptFormat("JSON");
$task1 = array('dataId' =>  uniqid(),
    'url' => 'http://xxxx.mp3',
);

/**
 * 语音垃圾内容检测： antispam。
 **/

// 如果是语音流检测，则live参数修改为true。
$request->setContent(json_encode(array("tasks" => array($task1),
    "scenes" => array("antispam"), "live" => false)));
try {
    $response = $client->getAcsResponse($request);
    print_r($response);
    if(200 == $response->code){
        $taskResults = $response->data;
        foreach ($taskResults as $taskResult) {
            if(200 == $taskResult->code){
                $taskId = $taskResult->taskId;
                // 将taskId保存下来，间隔一段时间来轮询结果。
                print_r($taskId);
            }else{
                print_r("task process fail:" + $response->code);
            }
        }
    }else{
        print_r("detect not success. code:" + $response->code);
    }
} catch (Exception $e) {
    print_r($e);
}
  • 提交语音本地文件
    <?php

include_once 'aliyuncs/aliyun-php-sdk-core/Config.php';
use Green\Request\V20180509 as Green;
use Green\Request\Extension\ClientUploader;

$iClientProfile = DefaultProfile::getProfile("cn-shanghai", "您自己的AccessKeyId", "您自己的AccessKeySecret");

$request->setMethod("POST");
$request->setAcceptFormat("JSON");
$uploader = ClientUploader::getVoiceClientUploader($client);
$url = $uploader->uploadFile("d:/暴恐涉政1.mp4");
// 如果是语音文件检测，type => file。
$task1 = array('dataId' =>  uniqid(),
    'url' => url,
    'type' => 'file'
);

/**
 * 语音垃圾内容检测： antispam。
 **/
$request->setContent(json_encode(array("tasks" => array($task1),
    "scenes" => array("antispam"))));
try {
    $response = $client->getAcsResponse($request);
    print_r($response);
    if(200 == $response->code){
        $taskResults = $response->data;

                // 将taskId保存下来，间隔一段时间来轮询结果。
                print_r($taskId);
