Speech-to-text crossed the "good enough for drafts" threshold years ago. In 2026, Whisper-large-class models on clean studio audio often exceed 95% word accuracy. That does not mean zero editing — it means editing is fast, not foundational.
What still breaks ASR
- Overlapping music — especially EDM or live drums under voice
- Heavy accents + rare domain terms — medical, legal, gaming handles
- Crosstalk — podcasts with three guests talking over each other
- Phone speaker audio — TikTok street interviews, etc.
Five-minute QA checklist
- Skim the first and last minute — intros/outros have the most name drops
- Search for your brand name and product names — fix capitalization
- Spot-check numbers, prices, and dates
- Export SRT and scan timestamp gaps > 3s for missed speech
- Read one random middle paragraph aloud — catches homophone errors ("their/there")
When to re-transcribe vs hand-edit
If more than one error per paragraph, re-run with better source audio (extract WAV, reduce background noise) before manual fixes. Hatcut resamples to 16 kHz mono before Whisper — the same prep pros use for API pipelines.
