This is quite strange behaviour, I can't understand why this happens. Notice the sentence at the beginning of the audio and at 20 seconds are very similar. But when arg "chunk_size 30" (default) it skips the first 20 second. Setting "chunk_size 20" or "chunk_size 10" helps. But why does this happen or is it normal whisperx behaviour, what do you think about it?
