我想要男性和女性语音的文本到语音的java代码，之后我想将该音频保存到wav文件。我尝试使用此代码，但它只给出男性声音。请建议我一种无需下载 jar 文件即可获得女性声音的方法（只需添加 maven 依赖项左右）。

目前使用此代码 -

     try

     {
     // set property as Kevin Dictionary
     System.setProperty("freetts.voices",
     "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");

     // Register Engine
     Central.registerEngineCentral("com.sun.speech.freetts.jsapi.FreeTTSEngineCentral");

     // Create a Synthesizer
     Synthesizer synthesizer = Central.createSynthesizer(new
     SynthesizerModeDesc(Locale.US));

     // Allocate synthesizer
     synthesizer.allocate();

     // Resume Synthesizer
     synthesizer.resume();

     // speaks the given text until queue is empty.
     synthesizer.speakPlainText("Hi, this is me. Fine.", null);
     synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);

     // Deallocate the Synthesizer.
     synthesizer.deallocate();
     }

     catch (Exception e) {
     e.printStackTrace();
     }

而这段代码 -

  try {
        System.setProperty("FreeTTSSynthEngineCentral", "com.sun.speech.freetts.jsapi.FreeTTSEngineCentral");
        System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");
        Central.registerEngineCentral("com.sun.speech.freetts.jsapi.FreeTTSEngineCentral");

        SynthesizerModeDesc desc = new SynthesizerModeDesc(null, "general", Locale.US, null, null);

        Synthesizer synth = Central.createSynthesizer(desc);
        synth.allocate();
        desc = (SynthesizerModeDesc) synth.getEngineModeDesc();
        Voice voice = new Voice();
        // "business", "casual", "robotic", "breathy"
        voice.setAge(Voice.AGE_TEENAGER);
        voice.setGender(Voice.GENDER_FEMALE);
        voice.setStyle("breathy");
        synth.getSynthesizerProperties().setVoice(voice);
        synth.resume();
        synth.speakPlainText("Hi, this is me. Fine.", null);
        synth.waitEngineState(Synthesizer.QUEUE_EMPTY);
        synth.deallocate();
    } catch (Exception ex) {
        ex.printStackTrace();
    }

但两者都发出男性声音（并且 KevinVoiceDirectory 中没有任何女性声音）。
