使用JAVA实现语音朗读一段文本

需求要用JAVA去调用windows自带的语音引擎去朗读一段文字,网上资料少得可怜,把百度和bing都翻遍了,总算找到一段代码,而且朗读起来还有感情色彩(win7测试),不过多音字还是暂时没解决。
需要做的工作:

1、下载jacob-1.17-M2.rar (内含demo示例)
rar地址:http://download.csdn.net/download/cjava_math/10234098

2、解压jacob-1.17-M2.rar

3、向工程里导入jacob.jar

4、将jacob-1.17-M2-x86.dll拷贝到jdk的bin目录和windows/system32目录

5、源代码如下

public static void main(String[] args) throws IOException {
    // ?? 这个Sapi.SpVoice是需要安装什么东西吗,感觉平白无故就来了
    ActiveXComponent sap = new ActiveXComponent("Sapi.SpVoice");
    // Dispatch是做什么的?
    Dispatch sapo = sap.getObject();
    try {

        // 音量 0-100
        sap.setProperty("Volume", new Variant(100));
        // 语音朗读速度 -10 到 +10
        sap.setProperty("Rate", new Variant(-2));

        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");
        // 执行朗读
        Dispatch.call(sapo, "Speak", new Variant("曾小明小朋友,早上好"));

    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        sapo.safeRelease();
        sap.safeRelease();
    }
    }
                                                            有其他更强大的技术,欢迎讨论!
