 1. 准备您的数据集。必须满足以下要求：
     - 文件结构不重要
+    - 每条音频长度必须在1-30秒之间，否则会被自动忽略
     - 所有音频文件必须是以下格式之一：`.wav` `.flac` `.mp3` `.m4a` `.opus` `.ogg`
     - 不需要说话人标签，但请确保每位说话人至少有 1 条语音
     - 当然，数据越多，模型的表现就越好

 1. Prepare your own dataset. It has to satisfy the following:
     - File structure does not matter
+    - Each audio file should range from 1 to 30 seconds, otherwise will be ignored
     - All audio files should be in on of the following formats: `.wav` `.flac` `.mp3` `.m4a` `.opus` `.ogg`
     - Speaker label is not required, but make sure that each speaker has at least 1 utterance
     - Of course, the more data you have, the better the model will perform
