Why some YouTube transcripts come out wrong
YouTube generates automatic captions for most videos, and for a clearly recorded monologue in English they are usually fine. The trouble starts when the recording is not clean. Two people talking over each other, a strong accent, background music, technical vocabulary, a phone recording in a room with hard walls — automatic captions degrade quickly in all of these, and no extraction tool can improve them, because it is copying a file that is already wrong.
The second gap is coverage. Livestreams, videos published in the last few hours, private and unlisted uploads, and many small channels have no caption track at all. An extractor has nothing to copy and returns an empty result, which is why so many of them fail silently on exactly the videos people care about.
Real transcription reads the audio instead of the caption file, so neither of those situations stops it. It costs more compute and takes longer than copying a text file — a two-hour podcast is a few minutes of work, not a few seconds — but it produces a transcript where there was none, and a correct one where the captions were wrong.
WhoScribe does the second. Paste a link and we transcribe the audio itself, with speaker labels and timestamps, in the original language or translated into any of 90+ others.
