- What happened
- Ruby-OPD improves Japanese text-to-speech by combining Ruby text representations with on-policy distillation to achieve 97.13% pronunciation accuracy while maintaining controllability.
- Why it matters
- Matters for engineers building Japanese TTS systems that need both accurate pronunciation handling of kanji-kana mixing and explicit control over output.
- Watch out
- Paper is marked work-in-progress with only five pages; no code or implementation details provided yet; results limited to Joyo-Kanji-Yomi benchmark.
