Question

我是FreeTTS的新手，这是我的第一个程序。以下程序只是读出一个字符串传递。

如果重要的话，我正在使用Linux Mint 32位。但是我在一天前在我的Windows机器上提取jsapi.jar。我相信这没关系。

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

public class Speak
{
    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);
            System.out.print("Speaking : "+speaktext);
            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);
            System.out.println(message);
        }
    }

    public static void main(String[] args)
    {
        Speak obj=new Speak();
        obj.dospeak("Finally It speaks and speaks and  speaks","kevin16");
    }
}

我将此作为礼物。

我不能接受这份礼物。

PS

我添加了所有4个档案en_us.jar，freetts-jsapi10.jar，jsapi.jar，mbrola.jar

Answer 1

1）找出通常定义这个类的jar：
com.sun.speech.freetts.ValidationException

2）看看你是否有罐子

3）看看你是否有正确版本的这个罐子（打开它，看看是否有类文件）

4）查看jar是否在运行时位于类路径中

FreeTTS Java程序中的ClassNotFoundException
