使用JAVA實現語音朗讀一段文本

需要做的工作：

1、下載  jacob-1.17-M2 或 jacob-1.18 

2、解壓jacob-1.17-M2 或 jacob-1.18 

3、向工程里導入jacob.jar

4、將 jacob-1.18-x64.dll 拷貝到jdk的bin目錄和windows/system32目錄

5、源代碼如下

public static void main(String[] args) throws IOException {
    // 這個Sapi.SpVoice是需要安裝什么東西嗎，感覺平白無故就來了
    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));
        // 語音朗讀速度 -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");
        // 執行朗讀
        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();
    }
    }

如果不行：
1.戴上耳機試試；
2.檢查下電腦上是否安裝了office（金山的wps不行）
