mbrola issue while using freetts in java

Question

I have used the following code to create voice using FreeTTs and Mbrola.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    Voice voice;
    VoiceManager vm = VoiceManager.getInstance();
    System.setProperty(“mbrola.base”, “C:\\mb\\”);
    voice=vm.getVoice(“mbrola_us3″);
    voice.allocate();
    voice.speak(“hello”);
    voice.deallocate();
}

I saved the required files in c:\mb but I receive the following exception:

Exception in thread “Thread-3″ java.lang.NoSuchMethodError: com.sun.speech.freetts.Voice.log(Ljava/lang/String;)V

Can you help me how to fix the problem?

Answer 1

NoSuchMethodError at compile time means the method does not exists or the method does not accept the String parameter.

I think its this method - voice.speak(“hello”); is the poblem or better you can use a try .. catch block and get the problem result using e.toString()
