Don't know which classes to start to test sphinx4

Question

I have done these steps

1- downloaded latest version of Sphinx4 from https://sourceforge.net/projects/cmusphinx/files/sphinx4/5prealpha/

2- installed Gradle IDE Pack 3.8.x + 1.0.x in Eclipse (Gradle plugin).

3- Imported Sphinx4 as Gradle STS project.

Now I got errors as shown in below picture

For the sake of time I have commented these errors because I don't know why these errors I am getting.

Now I want to RUN Sphinx4 but I dont know what to run and how to run. I have done my best with google and trying to do for days. but did not got positive results.

If any one can help me to solve the issue and guide me how to run sphinx4 as gradle that would be great. As you can see there are 4 projects sphinx so Which one to run.

That might be silly to ask, "If I run successfully what would be output"

PS: I am new to Gradle and Sphinx4 and also have taken look at this link

You can find tutorials: -> here <-

Although i am adding the jars to the classpath differently it will work for you.

Simple example code:

import java.util.logging.Logger;

    // Variables
    private String result;

    // Threads
    Thread  speechThread;

    // LiveRecognizer
    private LiveSpeechRecognizer recognizer;

        // if you want to use LanguageModelPath disable the 3 lines after which
        // are setting a custom grammar->

Grammar File:

#JSGF V1.0;

/**
 * JSGF Grammar 
 */

grammar grammar;

public <numbers> = (one | two | three| four| five | six | seven | eight | nine | ten);
public <action>  = (plus | minus | multiply | division);
public <final> = (show result);

Answer 2

These errors occur because your encoding isn't set right.

In Eclipse go to Edit -> Set Encoding -> UTF-8

Answer 3

Tutorial says

A number of sample demos are included in sphinx4 sources in order to give you understanding how to run Sphinx4. You can run them from sphinx4-samples jar:

• Transcriber - demonstrates how to transcribe a file
• Dialog - demonstrates how to lead dialog with a user
• SpeakerID - speaker identification
• Aligner - demonstration of audio to transcription timestamping

You just need to read it carefully.
