java - 使用 kevin 或 mbrola 时 Freetts 异常

Question

我正在尝试使用 freetts 运行一个程序。我能够编译该程序，但是我无法使用 kevin 或 mbrola 声音 我在最后得到以下输出消息

System property "mbrola.base" is undefined. Will not use MBROLA voices.
LINE UNAVAILABLE: Format is pcm_signed 16000.0 Hz 16 bits 1 channel big endian

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

class freetts {

    public static void main(String[] args) {
        try{ 
            Calendar calendar = new GregorianCalendar();
            String sayTime = "It is " + calendar.get(Calendar.HOUR) + " " + calendar.get(Calendar.MINUTE) + " " + (calendar.get(Calendar.AM_PM)==0 ? "AM":"PM");
            Synthesizer synth = Central.createSynthesizer(null);
            synth.allocate();
            synth.resume();
            synth.speakPlainText(sayTime, null);
            synth.waitEngineState(Synthesizer.QUEUE_EMPTY);
            synth.deallocate();
        }
        catch(Exception e){
            e.printStackTrace();
        }
    }
}

Answer 1

似乎“要为 MBROLA 启用 FreeTTS 支持，只需将 mbrola/mbrola.jar 复制到 lib/mbrola.jar。然后，无论何时运行任何 FreeTTS 应用程序，都将“mbrola.base”目录指定为系统属性:

  java -Dmbrola.base=/home/jim/mbrola -jar bin/FreeTTSHelloWorld.jar mbrola_us1"

我在以下位置找到了它:
