Decision table
| Dimension | Option A | Option B |
|---|---|---|
| Voice | Tone, identity, pronunciation | Check across episodes |
| Performance | Emotion, pauses, emphasis | Do not score only similarity |
| Timing | CPS/SPS, duration, alignment | Review against picture |
| Rights and output | Consent, tracks, mix, export | Keep release scope explicit |
