This release uses the clean English/Russian 25-second teacher and its matching eight-step CFG-3 distilled student. > **Important — Russian stress is automatic.** Text inside ` … ` receives > stress markers automatically by default. Explicit `+` markers always win. > > **Important — cross-language prompts.** When an English reference voice is > speaking Russian, experiment with `duration_scale` below `1` (for example > `0.8`).
