Core rule

Voice selection for Korean podcast operations should not be judged by a single "sounds good" score. The source rulebook separates four dimensions: distinction, cleanliness, stability, and long-listening fatigue. A voice can feel natural in one sample and still fail if it sounds distant, reverberant, or brittle across emotional samples.

Current candidate order

The current primary candidates are `01_charismatic`, `07_cold_detective`, and `05_wise`. `02_elegant` and `06_teacher` remain close or conditional candidates. Character-heavy voices such as `10_heroic`, `05_detective`, `04_villain`, and `08_rough` can be useful for limited roles, but should not be treated as default hosts.

Cleanup results

The first cleanup pass reduced room risk for the top three voices. A stronger close-v2 pass then lowered the measured room-risk score for `01_charismatic`, `07_cold_detective`, and `05_wise` to 0.0. The rulebook still keeps human listening as the final gate, because strong cleanup can make a voice thin or gated.

Operating checklist

Listen in this order: `dialogue`, `anchor`, and `calm`; then use `angry` and `surprised` to check cracking. For voices with room-risk flags, repeat `sad` and `calm` endings because reverberation is easiest to hear at the tail of a sentence. In a four-person podcast, avoid pairing voices that sit too close in pitch or timbre.
