TL;DR. Best with the LoRA at 50%, and by a wide margin — reward 0.775 vs 0.521 prompt-only and 0.671/0.598 at higher merges. Run the evolved prompt + 50% merge; it nearly doubles reward mainly by boosting vocal-burst blend (0.430 to 0.635) at low WER cost (0.214). The trade-off is speech quality/clarity: qual dips 0.565 to 0.498 and Articulation Clarity correlates strongly negative (-0.46), so delivery turns breathy and less crisp. The emo strength stays modest (0.071) — this LoRA sells the emotion through breathy vocalizations, not lexical arousal — so don't push to 150% (emo rises to 0.18 but reward drops and WER hits 0.52).
Without a LoRA
Best: evolved prompt, no LoRA → reward 0.52
GENERAL: A voice unmistakably expressing sexual lust, a husky, sultry voice, low and breathy, thick with desire and longing, pouring out.
