If you modify SpeechSourceProvider to return a constant microphone reference, it won't try to create multiple microphone references, which is the source of the issue.

public class SpeechSourceProvider {
    private static final Microphone mic = new Microphone(16000, 16, true, false);

    Microphone getMicrophone() {
        return mic;
    }
}

The problem here is that you don't want multiple threads trying to access a single resource, but for the demo, the recognizers are stopped and started as needed so that they aren't all competing for the microphone.
