Java文字转语音功能实现

需要下载jacob-1.18，网上一堆
项目中引入pom文件

<!-- https://mvnrepository.com/artifact/com.jacob/jacob 文字转语音 -->

合成：

public class Test {
    
    

	/**
	 * 语音转文字并播放
	 * 
	 * @param txt

	public static void textToSpeech(String text) {
    
    
		ActiveXComponent ax = null;
		try {
    
    
			ax = new ActiveXComponent("Sapi.SpVoice");

			// 运行时输出语音内容
			Dispatch spVoice = ax.getObject();
			// 音量 0-100
			ax.setProperty("Volume", new Variant(100));
			// 语音朗读速度 -10 到 +10
			ax.setProperty("Rate", new Variant(-2));
			// 执行朗读
			Dispatch.call(spVoice, "Speak", new Variant(text));

			// 下面是构建文件流把生成语音文件

			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("./text.mp3"), 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

			// 设置朗读速度

			// 关闭输出文件
			Dispatch.call(spFileStream, "Close");

			spAudioFormat.safeRelease();
			spFileStream.safeRelease();
			spVoice.safeRelease();
			ax.safeRelease();

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

	public static void main(String[] args) {
    
    
		String s = "当月亮和太阳处于地球两侧，并且月亮和太阳的黄经相差180度时，从地球上看，此时的月亮最圆，称之为“满月”";
		textToSpeech(s);
		File file = new File("result.mp3"); // 打开mp3文件即可播放
		String fileName = "Operator.doc".toString(); // 文件的默认保存名
		// 读到流中
		try {
    
    
			InputStream inStream = new FileInputStream("c:/Operator.doc");
		} catch (FileNotFoundException e) {
    
    
			// TODO Auto-generated catch block
			e.printStackTrace();
		} // 文件的存放路径
	}

}

但是项目启动后出现了no jacob-1.18-x64 in java.library.path

找不到的可以私信我。下载之后ddl文件放在JDK的目录下即可
