CMU sphinx livespeech example

Question

my goal is to let users speak by clicking a button and then when they click the button for stopping, the console outputs the result. I tried to apply the code that the CMU sphinx official website writes, as the following code:

LiveSpeechRecognizer recognizer = new LiveSpeechRecognizer(configuration);
// Start recognition process pruning previously cached data.
recognizer.startRecognition(true);
SpeechResult result = recognizer.getResult();
// Pause recognition process. It can be resumed then with startRecognition(false).
recognizer.stopRecognition();

This is how I implemented with zk-maven project:

public class SphinxSpeechRecog extends SelectorComposer<Component> {
    Configuration configuration = new Configuration();
    private LiveSpeechRecognizer recognizer;
    private SpeechResult result;

    public SphinxSpeechRecog() {
        // TODO Auto-generated constructor stub
    }

    @Listen("onClick=#speakbtn")
    public void startSpeaking() throws IOException, InstantiationException {
        //System.out.println("hi");
        configuration.setAcousticModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us");
        configuration.setDictionaryPath("resource:/edu/cmu/sphinx/models/en-us/cmudict-en-us.dict");
        configuration.setLanguageModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us.lm.bin");
        recognizer = new LiveSpeechRecognizer(configuration);

        recognizer.startRecognition(true);
        result = recognizer.getResult();
        recognizer.stopRecognition();

    }
    @Listen("onClick=#stopspeakbtn")
    public void stopSpeaking() {

        System.out.print("result: "+result);
    }

}

the frontend(.zul file):

<?page title="sphinx speech recognition" contentType="text/html;charset=UTF-8"?>
<zk>
    <window title="sphinx speech recognition" border="normal" apply="sphinx.SphinxSpeechRecog">
        <button id="speakbtn" label="speak"/>
        <button id="stopspeakbtn" label="stop speaking"/> 
    </window>
</zk>

The java(eclipse) console outputs some weird result like this (after so many minutes):

result: edu.cmu.sphinx.api.SpeechResult@3be41473

What can I do to optimize my code? And how to get the spoken words I really want to see?

Answer 1

for(WordResult word : result.getWords()) {
    System.out.print(word.toString());          
}
