## Notes

**Overall Transcript Quality:** Moderate to poor. Whisper struggled significantly with weed science terminology, herbicide product names, and chemical names throughout. The speaker's natural conversational pace and occasional garbled audio (satellite internet connection) compounded recognition errors. Technical sections (~20:00–36:00) contain the highest density of corrections.

**Dominant Error Patterns:**
1. Chemical/product name garbling — Whisper consistently phonetized herbicide names into unrelated English words ("penimethylene," "Glacisate," "glufosinite," "tranquil beer")
2. "Ornamental" consistently garbled — appeared as "ore metal," "water metals," "grape minerals," "bro woody or metals"
3. Botanical/technical terms rendered phonetically — "hypocotyl" → "hypocaudal," "radicle" → "radical," "dinitroaniline" → "dinitrietylene"
4. Speaker name inconsistency — Whisper rendered "Czarnota" differently in each introduction block

**Speaker Roster:** Dr. Mark Czarnota is not currently in the project speaker roster. Recommend adding:
- Dr. Mark Czarnota | Associate Professor of Horticulture (Weed Science), UGA Griffin Campus
