The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Overall, we achieve a 40% relative WER decrease for Whisper and a 50% relative WER decrease for MMS, indicating that a combination of data augmentation and LLM correction is a viable strategy for the recognition of OC speech.

C2weakest assumption

The synthetic data produced by the augmentation techniques sufficiently captures the acoustic variability of real oral cancer speech and the LLM corrections do not systematically alter medically relevant content.

C3one line summary

TTS data augmentation and LLM error correction together cut relative WER by 40-50% on ASR models for oral cancer speech.
