来自 Watson STT 的令人困惑的演讲者标签时间戳显示每个演讲者所说的秒数不正确

如何解决来自 Watson STT 的令人困惑的演讲者标签时间戳显示每个演讲者所说的秒数不正确

我正在编写一个脚本来转录 wav 文件中的单词。在 from 和 to 列中，我怀疑问题在于它显示了单词的时间戳，而不是说话者的整个句子的时间戳。这如何通过python纠正？这似乎不是 API 问题

我的脚本-

输出数据帧看起来像-

但是，from 和 to 时间戳没有任何意义，因为它们错误地显示在单词的开头以及同一个单词的结尾。而不是整个句子连续结束。可以做些什么来改变我的脚本？

您可以使用任何 wav 格式的音频文件来测试我的代码。我是新来的，不知道如何上传我的 wav 文件
