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

Answer 1

For me with this change, the problem was as long as i was staying in a context of cmusphinx it was good the line can be reused many times. But if i begin to reuse the mic for another work (like recording) it was not available!
I see that the stream was open in Microphone class but never close!

So first I change in class Microphone the following attributes from static to dynamic :

private TargetDataLine line;
private InputStream inputStream;

After i change the method stopRecording for closing stream before line:

  /**
 * close the stream and line
 */
public void stopRecording() {

    if (inputStream != null )
        try {
            inputStream.close();
        } catch (IOException e) {
            throw new IllegalStateException(e);
        }

    line.stop();

}

And now with no more change (class SpeechSourceProvider is original), i can reuse alternatively mic for cmupsphinx and another recording task
