Question

I am trying to run the dialog demo of sphinx 4 pre aplha but it gives errors.

I am creating a live speech application.

I imported the project using maven and

The answer of aetherwalker worked for me - in more detail I overwrote the following files with my own implementations where I only changed the used SpeechSourceProvider:

First one is the AbstractSpeechRecognizer:

public class MaxAbstractSpeechRecognizer {
protected final Context context;
protected final Recognizer recognizer;

protected ClusteredDensityFileData clusters;

protected final MaxSpeechSourceProvider speechSourceProvider;

/**
 * Constructs recognizer object using provided configuration.
 * @param configuration initial configuration
 * @throws IOException if IO went wrong
 */
public MaxAbstractSpeechRecognizer(Configuration configuration)
    throws IOException
{
    this(new Context(configuration));
}

protected MaxAbstractSpeechRecognizer(Context context) throws IOException {
    this.context = context;
    recognizer = context.getInstance(Recognizer.class);
    speechSourceProvider = new MaxSpeechSourceProvider();
} .......................

Then the LiveSpeechRecognizer:

public class MaxLiveSpeechRecognizer extends MaxAbstractSpeechRecognizer {

private final Microphone microphone;

/**
 * Constructs new live recognition object.
 *
 * @param configuration common configuration
 * @throws IOException if model IO went wrong
 */
public MaxLiveSpeechRecognizer(Configuration configuration) throws IOException
{
    super(configuration);
    microphone = speechSourceProvider.getMicrophone();
    context.getInstance(StreamDataSource.class)
        .setInputStream(microphone.getStream());
}......................

And last but not least the SpeechSourceProvider:

import edu.cmu.sphinx.api.Microphone;

public class MaxSpeechSourceProvider {

private static final Microphone mic = new Microphone(16000, 16, true, false);

Microphone getMicrophone() {
    return mic;
}
}
