162 CHAPTER 5 ■ SPEECH

Example 5-18 is useful when you want to hear what the Microsoft speech recognition
engine “hears.” You can use whatever voice you want. Here I’m using the MicrosoftVoice to
repeat what it hears.

Example 5-18. EchoTalk.java
package com.scottpreston.javarobot.chapter5;

public class EchoTalk {

private MicrosoftVoice voice;
private MicrosoftSR ear;

public EchoTalk() throws Exception {
// generic constructor gets instance of two worker classes
voice = MicrosoftVoice.getInstance();
ear = MicrosoftSR.getInstance();
// give user instructions
voice.speak("I will repeat what you say. Say exit, to end program.");
}

public void start() throws Exception {
String words = "";
// tell user to begin talking.
voice.speak("listening");
// this will loop until it hears 'exit'
while (words.equalsIgnoreCase("exit") == false) {
// gets words heard.
words = ear.listen();
//prints this to system out (good for debugging)
System.out.println("I heard --> " + words);
// say the words
voice.speak(words);
}
// last words spoken.
voice.speak("goodbye");
}

public static void main(String[] args) {

try {
EchoTalk echo = new EchoTalk();
echo.start();
