A machine learning engineer said he initially discovered hallucinations in about half of the over 100 hours of Whisper transcriptions he analyzed. The '100 hours' is almost useless information. 'About half' is meaningless without knowing the sample size. Perhaps he had 5 transcripts averaging 20 hours each, and 2 of the 5 had issues. Or perhaps there were hundreds of short transripts, where the 'almost half' would imply significance.
