How to combine small audio segments to make 30 seconds chunks in the dataset?

[omarabb315]

I am trying to prepare a dataset for whisper fine-tuning , and I have a lot of small segment clip , most of them less than 6 seconds, I read the paper, but didn’t understand this paragraph:

“ When a final tran- script segment is only partially included in the current 30- second audio chunk, we predict only its start time token for the segment when in timestamp mode, to indicate that the subsequent decoding should be performed on an au- dio window aligned with that time, otherwise we truncate the audio to not include the segment”

Anyone could help?
