1、下载jacob-1.18-M2.zip

2、解压，向工程导入jacob.jar

3、将jacob-1.18-M2-x64.dll复制到jdk的bin目录下，windows/system32最好也复制，不过我没复制也可以用

4、运行代码，注意这里输出文件和朗读不同时存在。

	public static void test3() {
		ActiveXComponent ax = null;
		
		try {
			ax = new ActiveXComponent("Sapi.SpVoice");
			Dispatch spVoice = ax.getObject();
			
			ax = new ActiveXComponent("Sapi.SpFileStream");
			Dispatch spFileStream = ax.getObject();
			
			ax = new ActiveXComponent("Sapi.SpAudioFormat");
			Dispatch spAudioFormat = ax.getObject();
			
			//设置音频流格式
			Dispatch.put(spAudioFormat, "Type", new Variant(22));
			
			//设置文件输出流格式
			Dispatch.putRef(spFileStream, "Format", spAudioFormat);
			//调用输出 文件流打开方法，创建一个.wav文件
			Dispatch.call(spFileStream, "Open", new Variant("D:\\test.wav"), new Variant(3), new Variant(true));
			//设置声音对象的音频输出流为输出文件对象
			Dispatch.putRef(spVoice, "AudioOutputStream", spFileStream);
			//设置音量 0到100
			Dispatch.put(spVoice, "Volume", new Variant(100));
			//设置朗读速度
			Dispatch.put(spVoice, "Rate", new Variant(-2));
			//开始朗读
			Dispatch.call(spVoice, "Speak", new Variant("这真是，蛋疼啊"));
			
			//关闭输出文件
			Dispatch.call(spFileStream, "Close");
			Dispatch.putRef(spVoice, "AudioOutputStream", null);
			
			spAudioFormat.safeRelease();
			spFileStream.safeRelease();
			spVoice.safeRelease();
			ax.safeRelease();
			
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
