How to pass real-time audio stream to the Direct Line Speech endpoint?

Question

I am trying to use Direct Line Speech (DLS) in my custom voice app. The Voice app has access to the real-time audio streams which I want to (pcm encoded) it directly to Dire

I believe your answer lies in the Microsoft.CognitiveServices.Speech.Audio.AudioConfig class. Have a look at this line in the Direct Line Speech client:

this.connector = new DialogServiceConnector(config, AudioConfig.FromDefaultMicrophoneInput());

AudioConfig provides many options besides FromDefaultMicrophoneInput. I suspect you'll want to use one of the three FromStreamInput overloads. If you do that then ListenOnceAsync will use your stream instead of the microphone.
