【Python】PC听书工具，微软tts朗读_edgetts python

简介：

使用edge-tts朗读txt文本。拥有“断点续读”的功能。会缓存一大堆的mp3文件，可以手动清理，也可以动手合成一个音频发b站之类的。: )

20231205更新：

现在把源码上传到gitee了，方便手机用termux时克隆代码到本地。txtReader: termux 上使用 或 windows 上使用的 txt阅读器 (gitee.com)

git clone https://gitee.com/harryxiaocn/txt-reader.git

20230921更新：

为了避免缓存不够，听起来断断续续的，现在三线程同时下载音频……

暂停之类的功能实现起来比较麻烦，就没弄了。
