自制实时翻译小工具

在开始，先说说这个小工具的来由。我计划在11月16号在东京举办一次《AI应用开发之旅》的社区活动（https://www.just-agi.com/event.html），活动华人为主，所以用中文，朋友说要带日本人过来，问有没有日语字幕，看了一下我的Teams，只有实时字幕，并没有翻译，于是就开始自己造轮子了。

这个小工具是用WinForm开发，只保留源语言文字和翻译后文字显示，其他部分作透明化处理，实时翻译的API调用的是Microsoft Speech的翻译API，10来分钟的工作量吧。

效果图：

正好这几天与营业部开会，试用了几次，总体的意思还是能搞清楚的，与现场的环境也有一定的关系。
