Speech-to-SFT pipeline ablation reveals data quality gains don't always boost downstream performance

A new research paper published on arXiv details a factorial ablation study of a speech-to-SFT pipeline, investigating the impact of different refinement stages on data quality and downstream model performance. The study found that while improvements in QA data quality consistently increased scores from LLM judges, these gains did not uniformly translate to better performance on downstream multiple-choice QA benchmarks. The positive transfer of improvements was concentrated on family-domain aligned pairs, suggesting a potential format mismatch between the SFT data composition and the nature of MCQA probes. AI

IMPACT Investigates how different stages of speech-to-SFT data refinement impact downstream model performance, highlighting potential mismatches between data quality improvements and benchmark gains.

    A Factorial Ablation of a Speech-to-SFT Pipeline: Differential Effects on Data Quality and Downstream Transfer

    arXiv:2608.20394v1 Announce Type: cross Abstract: Industry pipelines that turn speech into supervised fine-tuning (SFT) data via multi-stage refinement are increasingly adopted but, to our knowledge, have not been publicly ablated stage-by-stage, leaving each stage's marginal val…
