如何使用.NET SDK检测语音垃圾内容_内容安全(Content Moderation)-阿里云帮助中心

本文介绍了如何使用.NET 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。

功能描述

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API文档。

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。

前提条件

已安装.NET依赖。关于安装.NET依赖的具体操作，请参见安装.NET依赖。

说明

请一定按照安装.NET依赖页面中的版本安装，否则会导致调用失败。
