一、前言

本文基于Windows自带的SAPI.SpVoice，通过java代码实现文本转语音的功能。

二、实现流程

2.1 下载jacob-1.18.zip

链接：https://pan.baidu.com/s/1-zYB9I4VF5cPuj3ok1WLyg
提取码：7t1g

2.2 拷贝jacob-1.18-x64.dll

将 jacob-1.18-x64.dll拷贝到jdk的bin目录或windows/SysWOW64目录中

2.3 pom 添加依赖

<dependency><groupId>com.hynnet</groupId><artifactId>jacob</artifactId><version>1.18</version>
</dependency>

2.4 代码实现
