java - 语音合成空指针异常

Question

我得到空指针异常，我也知道原因。这是因为合成器获得空值。我应该怎么做才能删除这个？请帮忙

public class HelloWorld {

    public static void main(String args[]) {
        try {
           // Create a synthesizer for English
           Synthesizer synth = Central.createSynthesizer(new SynthesizerModeDesc(Locale.ENGLISH));

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

           synth.resume();

           // Speak the "Hello world" string

           synth.speakPlainText("Intiallizing the components, we are online and ready,sir", null);

          // Wait till speaking is done

          synth.waitEngineState(Synthesizer.QUEUE_EMPTY);

         // Clean up

         synth.deallocate();

    } catch (Exception e) {

         e.printStackTrace();

    }

}

即使在代码中包含所有 jar 文件之后，您也应该为字典设置属性并设置引擎。您可以通过在 try 中包含此代码块来完成此操作:

System.setProperty("freetts.voices","com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");
       Central.registerEngineCentral("com.sun.speech.freetts.jsapi.FreeTTSEngineCentral");
