JAVA Watson Speech to text using microphone (LIVE detection)

Question

so I'm making an application to dictate speech into a textbox using IBM Watson Speech to text java API. Essentially I want to remake the demo using a microphone in this link.

https://speech-to-text-demo.mybluemix.net/?cm_mc_uid=46038392292114635825813&cm_mc_sid_50200000=1464188794

I want to remake this in JAVA. So I have this sample code from their documentation

public class SimpleServlet {
  private static CountDownLatch lock = new CountDownLatch(1);

  public static void main(String[] args) throws FileNotFoundException, InterruptedException {
    SpeechToText service = new SpeechToText();
    service.setUsernameAndPassword("username","pass");

    //FileInputStream audio = new FileInputStream("src/test/resources/4.flac");

    AudioInputStream audio = null;


    RecognizeOptions options = new RecognizeOptions.Builder()
        .continuous(true)
        .interimResults(true)
        .contentType(HttpMediaType.AUDIO_FLAC)
        .build();

    service.recognizeUsingWebSocket(audio, options, new BaseRecognizeCallback() {
      @Override
      public void onTranscription(SpeechResults speechResults) {
        System.out.println(speechResults);
        if (speechResults.isFinal())
          lock.countDown();
      }
    });

    lock.await(1, TimeUnit.MINUTES);
  }
}

How would you open a socket to continuously add in an audiostream? If that is even the correct way to go about this.

Any help is appreciated.
