160 CHAPTER 5 ■ SPEECH

// sample program
public static void main(String args[]) {
int i;
i = 0;
String strRecognizedText;
System.out.println("Beginning speech recognition...");
// create speech recognition class
QuadmoreSR sr = new QuadmoreSR();
// wait until four words are heard
while (i < 4) {
strRecognizedText = sr.TakeDictation();
System.out.println("\n");
System.out.println(strRecognizedText);
i++;
}
System.out.println("Done.");
}
}

Just like Example 5-9, I could use the QuadmoreSR class in my programs, but I decided to
create a wrapper class that implements the SpeechRecognizer interface. There is no need to
implement the methods start(), stop(), open(), and close(), but they are required for the interface
so I will just create stubs. See Example 5-17.

Example 5-17. MicrosoftSR.java
package com.scottpreston.javarobot.chapter5;

public class MicrosoftSR implements JRecognizer {

// class used for recognizer
private QuadmoreSR ear;

// holds single instance of recognizer
private static MicrosoftSR instance;

// private constructor prevents initialization
// called by getInstance()
private MicrosoftSR() {

ear = new QuadmoreSR();
}
