import com.sun.speech.freetts.Voice;
import com.sun.speech.freetts.VoiceManager;
import com.sun.speech.freetts.audio.SingleFileAudioPlayer;
import java.io.FileInputStream;

public class Voice{

void call(String msg){
System.out.println("U r here");
Voice voice;
FreeTTS freetts;
System.out.println("---------************");
VoiceManager vm=VoiceManager.getInstance();
System.out.println("--------------////");
voice=vm.getVoice("kevin16");
System.setProperty("com.sun.speech.freetts.voice.defaultAudioPlayer", "com.sun.speech.freetts.audio.SingleFileAudioPlayer");
FileInputStream fis ;
SingleFileAudioPlayer sfap;
if(voice==null)
System.out.println("voice is null");
System.out.println("---0---");
if(voice!=null)
{
voice.allocate();
}
System.out.println("---1---");
freetts=new FreeTTS(voice);
String text = new String(msg);
byte b[] = text.getBytes();
if(b==null)
{
System.out.println("no byte array");
System.exit(1);
}
try
{
sfap = (SingleFileAudioPlayer)voice.getDefaultAudioPlayer();
sfap.write(b);


}
catch(Exception e)
{

}
voice.speak(msg);
voice.deallocate();

System.out.println("---------?????-----------");
try {
System.out.println("inside copy try block");
String command="copy \"C:\\Program Files\\Apache Software Foundation\\Apache Tomcat 6.0.18\\bin\\freetts.wav\" \"C:\\Program Files\\Apache Software Foundation\\Apache Tomcat 6.0.18\\webapps\"";
System.out.println("copying file from "+command);
Runtime.getRuntime().exec("cmd.exe /c"+command);
System.out.println("file copied");
