疑难解答“系统属性 mbrola.base 未定义。不会使用MBROLA声音”使用 FreeTTS 将文本转换为语音时
import com.sun.speech.freetts.*;
import java.util.*;
public class Demofreetts
{
private String speaktext;
public void doSpeak(String speak, String voice)
{
speaktext = speak;
try
{
VoiceManager voiceManager = VoiceManager.getInstance();
Voice voices = voiceManager.getVoice(voice);
Voice sp = null;
if(voices != null)
sp = voices;
else
System.out.println("No Voice Available");
sp.allocate();
sp.speak(speaktext);
sp.deallocate();
}
catch(Exception e)
{
e.printStackTrace();
}
}
public static void main(String[]args)
{
Demofreetts obj = new Demofreetts();
obj.doSpeak(args[0],"Kelvin16");
}
}
上面的代码会导致以下错误：
System property "mbrola.base" is undefined. Will not use MBROLA voices
No Voice Available
java.lang.NullPointerException
at Demofreetts.doSpeak(Demofreetts.java:24)
at Demofreetts.main(Demofreetts.java:39)
import com.sun.speech.freetts.*;
import java.util.*;
public class Demofreetts
{
private String speaktext;
public void doSpeak(String speak, String voice)
{
speaktext = speak;
try
{
VoiceManager voiceManager = VoiceManager.getInstance();
Voice voices = voiceManager.getVoice(voice);
Voice sp = null;
if(voices != null)
sp = voices;
else
System.out.println("No Voice Available");
sp.allocate();
sp.speak(speaktext);
sp.deallocate();
}
catch(Exception e)
{
e.printStackTrace();
}
}
public static void main(String[]args)
{
Demofreetts obj = new Demofreetts();
obj.doSpeak(args[0],"Kelvin16");
}
}
The above code causes the following error:
System property "mbrola.base" is undefined. Will not use MBROLA voices
No Voice Available
java.lang.NullPointerException
at Demofreetts.doSpeak(Demofreetts.java:24)
at Demofreetts.main(Demofreetts.java:39)

只需添加 System.setProperty
just add System.setProperty
这是解决方案
将字符串语音参数更改为以下之一。
1.kevin16（所有字母均应小写）
2.alan（这也是您替代 kevin16 语音的下一个选择。
但消息
系统属性“mbrola.base”未定义。不会使用 MBROLA 声音。仍然存在，但你可以获得你需要的声音。幸运的是，你可以通过设置 mbrola 声音的属性来解决这个问题。不管怎样
，它对我有用，请尝试一下。
