Speaker Identification runs forever

[themoonraker13]

I've developed a Java program that consumes sphinx to perform speaker-clustering using SpeakerIdentification.
The program/algorithm works fine giving outputs in the same amount of time when I test it with small audio files with similar attributes(time duration, bit-rate, mono/stereo, etc.)

The program run into trouble when I supply it with a large audio file i.e. greater than 1-1.5 hour (wav, 16khz, mono, pcm). The program runs for many hours and sometimes runs forever if the file is excessively large.

I do not know if I'm consuming sphinx the right way. Please guide me solve the problem as it would help me optimize my application's performance to a great extent.

hi,
did you success on speaker identification, if you got success can you help me to do that.
I m getting error on and please help how to run it.

File voiceFile = new File("output2.wav");
URL url = voiceFile.toURI().toURL();
ArrayList clusters = sd.cluster(url.openStream());

Thanks in advance

Seems like you are consuming the SpeakerIdentification implementation of CMU Sphinx in a wrong way.

I had implemented a SpeakerID java class long back which used to accept a audio file name as command-line argument and print speaker identification/clustering information on console. Hope this might help you.

public class SpeakerID {
    public static void main(String args[]) {
        try {
            SpeakerIdentification speakerIdentification = new SpeakerIdentification();
            InputStream fin = new FileInputStream(new File(args[0]));
            ArrayList<SpeakerCluster> clusters = speakerIdentification.cluster(fin);

            int clusterid=1;
            for (SpeakerCluster cluster : clusters) {
                ArrayList<Segment> segments = cluster.getSpeakerIntervals();
                System.out.println("########################");
                System.out.println("Cluster: " + clusterid);
                int segmentid = 1;
                for (Segment s : segments) {
	            long startTime = s.getStartTime();
	            long endTime = s.getStartTime() + s.getLength();
	            System.out.println("---------------");
	            System.out.println("Segment: " + segmentid);
	            System.out.println("Start Time: " + startTime);
	            System.out.println("End Time: " + endTime);
	            System.out.println("---------------");
	            segmentid++;
               }
               clusterid++;
               System.out.println("########################");
            }
        } catch (Exception e) {
	    e.printStackTrace();
        }
    }
}

Thanks for reply but again i am getting the same error.

InputStream fin = new FileInputStream(new File("test.wav"));
ArrayList clusters = speakerIdentification.cluster(fin);

Dear Sir,

Actually i want to make an application in java where if user voice authenticate then it should print welcome else it should say invalid credential, if you have something like this can share with me and that will be great help for me.

Thanks in advance

@cris7M please read the following to understand about this type of exception in general:

Check the Apache Commons Math API used by CMU Sphinx and verify that the method actually exist. If not, try changing the API version.
