我是youtube字幕的新手。我的问题是从youtube逐句生成标题文件（格式vtt）。我尝试编写纯文本文件并将其上传到youtube。 Youtube正确生成标题文件，但不是逐句生成。我想知道我是否一个接一个地想要vtt文件，那么我需要以哪种格式编写我的纯文本文件？按照我尝试过的例子：
纯文本文件：
Good day, everyone, and welcome to this meeting of earnings release conference call. Today's call is being recorded. At this time for opening remarks and introductions, I would like to turn the call over to Anand Soni, Senior Director of Investor Relations. Please go ahead, sir.
Youtube生成如下：
WEBVTT 1 00:00:00.110 --> 00:00:03.759 Good day, everyone, and welcome to this meeting of earnings release conference 2 00:00:03.759 --> 00:00:07.860 Call. Today's call is being recorded. At this time for opening remarks and introductions, 3 00:00:07.860 --> 00:00:10.809 I would like to turn the call over to Anand Soni. Senior Director of Investor Relations. Please go ahead, sir.
我想这样：
WEBVTT 1 00:00:00.110 --> 00:00:03.759 Good day, everyone, and welcome to this meeting of earnings release conference Call. 2 00:00:03.759 --> 00:00:07.860 Today's call is being recorded. 3 00:00:07.860 --> 00:00:10.809 At this time for opening remarks and introductions,I would like to turn the call over to Anand Soni. 4 00:00:010.809 --> 00:00:11.809 Senior Director of Investor Relations. Please go ahead, sir.
我通过编程语言Ruby来做所有上述事情。我想知道我的纯文本文件在格式化方面需要做些什么，以便youtube会按句子vtt文件生成预期的句子？
感谢。
