第一次应用程序工作正常。但是当我第二次单击“语音”按钮时它会出错

这是代码。

public void speechFile(){

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();
        }
    }

我不明白的是首先它工作正常。第二次出错。如何解决这个问题。

我对这个库或技术知之甚少，但对我来说，每次使用都要注册一次引擎似乎很奇怪，而且很奇怪你不会重用现有的合成器。

您是否尝试过创建合成器一次并使用它两次？

要使代码多次读取，您只需删除 synth.deallocate(); 从您的代码中，您将能够循环到您想要的为止。
