Why

Gemini 3.8 Flash is a better judge than Gemini 3.0 Flash.

What changes

  • AudioJudgeMetric.default_model: gemini-3-flash-preview → gemini-3.8-flash, with the same parameters.
  • Docs: the judge model in docs/metrics/README.md, the three speech-fidelity metric pages and the judge table in docs/experiment_setup.md.
  • Website: the judge model of the three speech-fidelity metrics on the methodology page (website/src/data/metricsData.ts). The site is not rebuilt here.
  • tests/fixtures/metric_signatures.json regenerated.

Before merging

  • The judge accuracy shown on the website (0.8957) was measured with Gemini 3 Flash; it has not been re-measured with Gemini 3.8 Flash.
  • Re-build the website.
