Usage

In your Unity scene, create a new GameObject and attach the StreamingRecognizer MonoBehavior to it.

If you want to quickly test that things are working, check the Enable Debug Logging option on the StreamingRecognizer, then play your scene. You should see some debugging messages appear in the Console, along with a live transcription of any speech audible to your computer's microphone.
