The author details five critical mistakes made while fine-tuning the F5-TTS text-to-speech model for a new writing system. These errors, primarily related to loading the correct model weights and verifying vocabulary changes, led to significant wasted GPU time. The author emphasizes the importance of rigorous measurement and cross-validation, such as diffing vocabulary files and asserting tensor matches, to avoid such pitfalls. AI
