关于Java使用Sapi.SpVoice语音合成问题

[穆牧]

ActiveXComponent sap = new ActiveXComponent("Sapi.SpVoice");
Dispatch sapo = sap.getObject();

try {

sap.setProperty("Volume", new Variant(volume));
sap.setProperty("Rate", new Variant(rate));

Variant defalutVoice = sap.getProperty("Voice");

Dispatch dispdefaultVoice = defalutVoice.toDispatch();
Variant allVoices = Dispatch.call(sapo,"GetVoices");
Dispatch dispVoices = allVoices.toDispatch();

Dispatch setvoice = Dispatch.call(dispVoices, "Item", new Variant(1)). toDispatch();
ActiveXComponent voiceActivex = new ActiveXComponent(dispdefaultVoice);
ActiveXComponent setvoiceActivex = new ActiveXComponent(setvoice);

Variant item = Dispatch.call(setvoiceActivex, "GetDescription");

Dispatch.call(sapo, "Speak", new Variant(message));

} catch (Exception e) {
e.printStackTrace();
} finally {
sapo.safeRelease();
sap.safeRelease();
}

使用以上代码可以实现将文字转换成语音朗读，但只是调用windows系统设置的默认语音库，想要换语音库还要进控制面板-语音进行语音库选择。求如何实现在代码中调用不同语音库进行朗读。

或者提供能完成以上功能的其他方式的源码也可以。
