    Can you post a small program that compiles, execute and shows the problems.
    Also copy the full text of the error messages and post it here.
    If you don't understand my answer, don't ignore it, ask a question.

    Synthesizer synth = Central.createSynthesizer(
    new SynthesizerModeDesc(Locale.ENGLISH));

    // Get it ready to speak
    synth.allocate();
    synth.resume();

    // Speak the "Hello world" string
    synth.speakPlainText("Hello, world!", null);

    // Wait till speaking is done

    Where did you get the javax.speech package you are using?
