众所周知，由于阅读障碍和其他学习障碍，有些人难以阅读大量文字。有些人具有基本的文学水平。他们经常尝试浏览Internet时感到沮丧，因为其中很多都是文本形式的，或者另一方面，某些人更喜欢听或看新闻文章(或类似的东西)而不是阅读。因此，要解决所有这些问题，就会想到一个概念，即“文本到语音”。

打开电脑自带TTS语音路径

Balabolka

http://balabolka.site/balabolka.htm

是一个文本到语音 (TTS) 程序。Balabolka可以使用您系统上安装的所有计算机语音。屏幕上的文本可以保存为音频文件。该程序可以读取剪贴板内容、从文档中提取文本、自定义字体和背景颜色、从系统托盘或全局热键控制读取。 Balabolka支持文本文件格式：AZW、AZW3、CHM、DjVu、DOC、DOCX、EML、EPUB、FB2、FB3、HTML、LIT、MD、MOBI、ODP、ODS、ODT、PDB、PRC、PDF、PPT、PPTX、 RTF、TCR、WPD、XLS、XLSX。

eSpeak

http://espeak.sourceforge.net/index.html

eSpeak 是一款小巧的开源软件语音合成器，可以将语音输出生成为 WAV 文件，适用于中文和其他语言，适用于 Linux 和 Windows

http://espeak.sourceforge.net/test/latest.html

中文简体文本需要编码为ANSI

安装界面，中文zh zh+f5

要使用语言的替代语音，您可以选择其他命令来更改各种语音和发音属性。有关更多信息，请访问http://espeak.sourceforge.net/voices.html。通过附加加号 ( + ) 和变体名称，可以将预设语音变体应用于任何语言语音。男声的变体是+m1、+m2、+m3、+m4、+m5、+m6和+m7。女声的变体是+f1、+f2、+f3、+f4和+f5. 您还可以选择可选的语音效果，例如+croak或+whisper。
