我試圖在我的 Java 程序（來自https://freetts.sourceforge.io/docs/index.php）中使用 FreeTTS并且我收到此錯誤：java.lang.ClassCastException: com.sun.speech.freetts.en.us.cmu_time_awb.AlanVoiceDirectory cannot be cast to com.sun.speech.freetts.VoiceDirectory我嘗試將免費 TTS jar 文件重新添加到我的項目中，這是我的代碼：import com.sun.speech.freetts.Voice;import com.sun.speech.freetts.VoiceManager;public class TextToSpeech {//String voiceName = "kevin16";VoiceManager freeVM;Voice voice;public TextToSpeech(String words) { freeVM = VoiceManager.getInstance(); voice = VoiceManager.getInstance().getVoice("kevin16"); if (voice != null) { voice.allocate();//Allocating Voice } try { voice.setRate(190);//Setting the rate of the voice voice.setPitch(150);//Setting the Pitch of the voice voice.setVolume(3);//Setting the volume of the voice SpeakText(words);// Calling speak() method } catch (Exception e1) { e1.printStackTrace(); }}public void SpeakText(String words) { voice.speak(words);}我TextToSpeech從另一個類調用構造函數，如下所示： new TextToSpeech("Hello World");將不勝感激任何幫助或建議！

像這樣更改 TextToSpeech 構造函數：
public TextToSpeech(String words) {
System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");
voice = VoiceManager.getInstance().getVoice("kevin16");
if (voice != null) {
voice.allocate();// Allocating Voice
try {
voice.setRate(190);// Setting the rate of the voice
voice.setPitch(150);// Setting the Pitch of the voice
voice.setVolume(3);// Setting the volume of the voice
SpeakText(words);// Calling speak() method
} catch (Exception e1) {
e1.printStackTrace();
}
} else {
throw new IllegalStateException("Cannot find voice: kevin16");
}
}
這個想法是指示 freetts 使用com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory類而不是AlanVoiceDirectory類。

代碼更改：
而不是以下行
freeVM = VoiceManager.getInstance();
voice = VoiceManager.getInstance().getVoice("kevin16");
修改為
freeVM = VoiceManager.getInstance();
voice = freeVM.getVoice("kevin16");
