使用 Microsoft 音频堆栈 (MAS)
项目
语音 SDK 集成 Microsoft 音频堆栈 (MAS),允许任何应用程序或产品对输入音频使用其音频处理功能。 有关概述,请参阅音频处理文档。
本文介绍如何将 Microsoft 音频堆栈 (MAS) 与语音 SDK 结合使用。
重要
在适用于 C++ 和 C# v1.33.0 及更高版本的语音 SDK 上,必须安装 Microsoft.CognitiveServices.Speech.Extension.MAS 包才能在 Windows 上使用 Microsoft 音频堆栈;如果你使用 NuGet 来安装语音 SDK,则必须在 Linux 上使用 Linux 音频堆栈。
