如何在Java netbeans中使用TTS(文本到语音)?

我正在努力让一个TTS在java的netbeans中工作。我解压缩了JSAPI文件并将以下jar添加到库

  • cmu_us_kal.jar
  • cmulex.jar
  • en_us.jar
  • freetts.jar
  • cmulex.jar
  • jsapi.jar

当我运行以下代码时:

package demofreetts2;

import javax.speech.*;
import java.util.*;
import javax.speech.synthesis.*; 

public class Demofreetts2 {

String speaktext ="";
public void doSpeak(String speak, String voicename)
 {
   speaktext = speak;
   String voiceName = voicename;
   try
    {
    SynthesizerModeDesc desc = new SynthesizerModeDesc(null, "general", Locale.US, null, null);
     Synthesizer synthesizer = Central.createSynthesizer(desc);
     synthesizer.allocate();
     synthesizer.resume();
     desc = (SynthesizerModeDesc)synthesizer.getEngineModeDesc();
     Voice[] voices = desc.getVoices();
     Voice voice = null;
     for(int i = 0; i< voices. length; i++)
      {
       if(voices[i].getName().equals(voiceName))
        {
         voice = voices[i];
         break;
        }
      }
     synthesizer.getSynthesizerProperties().setVoice(voice);
     synthesizer.speakPlainText(speaktext, null);
     synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);
     synthesizer.deallocate();
    }
   catch (Exception e)
    {
    String message = "missing speech properties in " + System.getProperty("user.home") + "\n";
        System.out.println (""+e);
    }
 }
public static void main (String[]args)
{
 Demofreetts2 obj = new Demofreetts2();
  obj.doSpeak(args[0],"kevin16");
 }
}

我收到以下消息:

**run:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at demofreetts2.Demofreetts2.main(Demofreetts2.java:46)
Java Result: 1
BUILD SUCCESSFUL (total time: 1 second)**

当我改变主要方法时:

public static void main (String[]args)
{
 Demofreetts2 obj = new Demofreetts2();
 obj.doSpeak("hello","kevin16");
}

我收到此消息:

**run:
java.lang.NullPointerException
BUILD SUCCESSFUL (total time: 1 second)**

有谁知道如何才能让它发挥作用?

我只是将字符串转换为语音的程序。

答案 0 :(得分:0)

错误#1:您必须将一些参数传递给main方法才能使用args[0]。有关其他信息,请参阅What is "String args[]"? parameter in main method Java

错误#2:您在代码中遇到NullPointerException,这意味着您尝试在等于null的实例上使用方法。要么使用调试器,要么使用e.printStackTrace();而不是System.out.println (""+e);扩展调试信息,以便知道哪个实例是罪魁祸首。
