Why Narrow Speech Tasks Still Need Large Models

Building speech recognition for short navigation addresses seems like a job for a tiny model trained from scratch. However, transfer learning research on Parakeet and QuartzNet shows that small datasets cause models to overfit or forget acoustic fundamentals without massive pretrained priors. Exploring catastrophic forgetting, format scoring artifacts on the AN4 corpus, and knowledge distillation reveals why even the most specific audio tasks perform best when starting from large foundation models rather than clean slates.
