and this is the code for sphinx

public static Configuration configuration;
public static LiveSpeechRecognizer recognize;
public static SpeechResult result;
public static String Sphinx_Result;

public static void Sphinx() throws InterruptedException{

     try {

        configuration = new edu.cmu.sphinx.api.Configuration();
        configuration.setAcousticModelPath("resource:/edu/cmu/sphinx/models/en-us/en-us");
        configuration.setDictionaryPath("file:C:/HBSN/Dictioanary-1000.dic");
        configuration.setLanguageModelPath("file:C:/HBSN/Language Model-1000.lm");

        configuration.setUseGrammar(false);
        recognize = new LiveSpeechRecognizer(configuration);
        recognize.startRecognition(true);

        while ((result = recognize.getResult()) != null) {

            Sphinx_Result = result.getHypothesis();

        }

        recognize.stopRecognition();

    } catch (IOException e) {

       main.Error("Error In Sphinx", " sphinx speech recognition unit not working");

    }  


}

used APIs are

  • sphinx4-core-1.0.0.jar

  • sphinx4-data-1.0.0.jar

How can i resolve this issue.

You are trying to use compromised jars. You can get latest jars from official website. They should have version 5prealpha, not 1.0.0.

  • Hi Nikolay,I tried it.Even it gives the same error. – Hasitha Buddika Oct 14 '17 at 08:24
  • I do not think you understand what is going on and update the project properly. You can consult for details https://stackoverflow.com/questions/2877262/java-securityexception-signer-information-does-not-match – Nikolay Shmyrev Oct 14 '17 at 13:12
  • I created another project with only Sphinx part with the same APIs & the same code.It works perfectly.Only this project gives me this error.If signatures are not matching , how is the second project runs without any errors – Hasitha Buddika Oct 15 '17 at 05:37
  • Most likely you still link old corrupted jars in the first project. – Nikolay Shmyrev Oct 16 '17 at 08:03
  • In both projects , I used the same jar files.That's why I couldn't find the exact cause of the error – Hasitha Buddika Oct 16 '17 at 10:19
