Here is the code.

String context=jTextArea1.getText();
        try
 {
   System.setProperty("freetts.voices","com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");

   Central.registerEngineCentral("com.sun.speech.freetts.jsapi.FreeTTSEngineCentral");
   Synthesizer  synthesizer =Central.createSynthesizer(new SynthesizerModeDesc(Locale.US));
   synthesizer.allocate();
   synthesizer.resume();
   synthesizer.speakPlainText(context, null);
   synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);
   synthesizer.deallocate();
  }
   catch(IllegalArgumentException e)
   {
     e.printStackTrace();
   }    catch (InterruptedException e) {
       e.printStackTrace();
        } catch (AudioException e) {
            e.printStackTrace();
        } catch (EngineException e) {
            e.printStackTrace();
        }
    }

to make the code read more than once, all you have to do to remove the synth.deallocate(); from your code, then you will be able to loop till you want.

I don't know much about this library or technique, but to me it seems odd that you would register the engine once for each use, and odd that you wouldn't reuse an existing synthesizer.

Have you tried creating the synthesizer once and using it twice?
