我正在尝试为 C# Windows 窗体应用程序可执行文件找到免费的语音识别，它可以作为谷歌语音识别，识别并将绝对新词转换为文本。

我尝试使用 System.Speech.Recognition；不同的方式，但它适用于预先录制的命令，我无法获得这样的结果，例如它与 Python 的 Google Speech Recognition 一起使用，这至少是 95% 的正确结果，足以说，这很好，但显然，如果我没有密钥，它就不能免费使用，也不能在可执行文件中使用。

所以我想试试微软认知服务的 Bing Speech API，但找不到任何如何编码的例子，一些基本的例子。如果有人处理过这个工具，你能帮我弄清楚吗

嗨，也许这可以帮助你一个简单的 bing 语音 api 示例，这不是 winform 这是用于 WPF 应用程序 C#
