java实现文字转语音播报功能

一、pom.xml引入jar包依赖

<!-- https://mvnrepository.com/artifact/com.jacob/jacob 文字转语音 -->
<dependency>
  <groupid>com.hynnet</groupid>
  <artifactid>jacob</artifactid>
  <version>1.18</version>
</dependency>

二、把jacob-1.18-x64.dll文件复制到jdk安装位置的bin目录下。

https://files.cnblogs.com/files/w1441639547/jacob-1.18-x64.rar

三、把jacobtest.java类导入至项目中测试运行。

package com.interface.util;

import com.jacob.activex.activexcomponent;
import com.jacob.com.dispatch;
import com.jacob.com.variant;

            dispatch.put(spvoice, "rate", new variant(-2));
            // 开始朗读
            dispatch.call(spvoice, "speak", new variant(txt));

            // 关闭输出文件
            dispatch.call(spfilestream, "close");
            dispatch.putref(spvoice, "audiooutputstream", null);

            spaudioformat.saferelease();

            spvoice.saferelease();
