科大讯飞语音合成 文本转语音
一、引入依赖：
<dependency>
<groupId>net.java.dev.jna</groupId>
<artifactId>jna</artifactId>
<version>5.5.0</version>
</dependency>
二、下载响应的sdk，我这里是下载的java win版本的sdk
SDK下载 - 科大讯飞api接口 - 讯飞开放平台
三、具体代码：
从下载的依赖里面找到对应文件，给代码里面替换成你的绝对路径，运行即可文章来源：https://www.toymoban.com/news/detail-606182.html
备注：这个地方需要你自己的账号下载的才能使用，因为他官方做了sdk校验文章来源地址https://www.toymoban.com/news/detail-606182.html
