    Your Post controller takes an Activity as an argument. The Audio message will show up in the Attachment array as a link to the audio location provided by Facebook. You can pass that to the Bing Speech API. One thing to note that the ContentType provided by Facebook is “video/mp4” (which could be confusing).

    You get an attachment of the type “audio/aac”. You need to access it via your activity object.

    var sound = activity.Attachments?.FirstOrDefault(a => a.ContentType.Equals("audio/aac"));

    Now you can easily access the actual message via sound.ContentUrl and have a URI to the file, which you then can put into an encoder to convert it to wav. Then you can put it into you Bing speech Api.
