TL;DR: Whisper occasionally hallucinates and credits “Nicolai Winther” at the ends of Norwegian transcriptions during silent audio segments, likely because the real Nicolai Winther - a former YouTuber who created subtitles—appears frequently in its (likely YouTube‑based) training data. This highlights how limited Norwegian training (only ~266 hours) can cause the model to overfit on specific names and phrases when uncertain.
