Is there any well known established framework for C or Java or PHP to do speech recognition applications? Microphone audio input and it will recognize English words. Such as pseudo code:

Speech s = new Speech();
s.input(micStream);
result = s.recognise("Hello");
if (result) { printf("Matched hello"); } else { printf("No match found"); }

    b) use this:

    package edu.cmu.sphinx.demo.hellowrld;
    import edu.cmu.sphinx.frontend.util.Microphone;
    import edu.cmu.sphinx.recognizer.Recognizer;
    import edu.cmu.sphinx.result.Result;
    import edu.cmu.sphinx.util.props.ConfigurationManager;
    import java.io.IOException;
    import java.util.logging.Level;
    import java.util.logging.Logger;
    import models.Tts;
    
    public class Speech {
    
      public static void main(String[] args) {
        ConfigurationManager cm;
    
        if (args.length > 0) {
            cm = new ConfigurationManager(args[0]);
        } else {
            ///tmp/helloworld.config.xml
            cm = new ConfigurationManager(Speech.class.getResource("speech.config.xml"));
    
        }
        Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
        recognizer.allocate();
    
        Microphone microphone = (Microphone) cm.lookup("microphone");
        if (!microphone.startRecording()) {
            System.out.println("Cannot start microphone.");
            recognizer.deallocate();
            System.exit(1);
        }
    
        System.out.println("Say: (Hello | call) ( Naam | Baam | Caam | Some )");
    
        while (true) {
            System.out.println("Start speaking. Press Ctrl-C to quit.\n");
    
            Result result = recognizer.recognize();
    
            if (result != null) {
                String resultText = result.getBestFinalResultNoFiller();
                System.out.println("You said: " + resultText + '\n');
    
                    Tts ts = new Tts();
                    try {
                        ts.load();
                        ts.say("Did you said: " + resultText);
                    } catch (IOException ex) {
    
                    } 
            } else {
                System.out.println("I can't hear what you said.\n");
            }
        }
      }
    }
