Answer 1

use a SpeakableListener when do text to speak.

private volatile boolean finished;

private SpeakableListener listener = new SpeakableListener() {

    @Override
    public void markerReached(SpeakableEvent arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void speakableCancelled(SpeakableEvent arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void speakableEnded(SpeakableEvent arg0) {
        TestSpeaker.this.finished = true;

    }

    @Override
    public void speakablePaused(SpeakableEvent arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void speakableResumed(SpeakableEvent arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void speakableStarted(SpeakableEvent arg0) {
        TestSpeaker.this.finished = false;

    }

    @Override
    public void topOfQueue(SpeakableEvent arg0) {
        // TODO Auto-generated method stub

    }

    @Override
    public void wordStarted(SpeakableEvent arg0) {
        // TODO Auto-generated method stub

    }
};

/** Speak the following string. */
public void sayIt(String str) {
    System.out.print(" " + str + " ");
    /* The the synthesizer to speak. */
    synthesizer.speakPlainText(str, listener);
