Nov 1, 2025November 2025: Delivered major Wav2Vec2 ASR pipeline enhancements for facebookresearch/fairseq2, focusing on end-to-end training/evaluation improvements, data handling, and configuration clarity. Refactored preprocessing and overall structure to enable streamlined ASR workflows, with a stronger emphasis on reproducibility and maintainability. Fixed evaluation reliability by switching WER calculations from tensors to lists for robust edit-distance compatibility, and achieved ASR parity within 0.01 WER against reference runs. These changes reduce maintenance overhead, enable faster experimentation, and improve model evaluation stability.
