TL;DR. Best reward is without a LoRA (plain BASE 0.490, barely ahead of BASE_P 0.468 and LoRA50 0.474), but be aware the actual disgust signal is essentially zero (~0.001-0.003) in all of these — the model does not natively voice disgust. Only LoRA150 makes disgust audible (emo 0.236), at a punishing cost: WER 0.856 and quality down to 0.308. Its side-effect is that it doesn't produce clean disgust but shoves the delivery into Anger and Impatience (shift +1.31/+1.27) plus Fear, so you get an enraged read, not a revolted one. Recommendation: use the prompt for best reward if literal disgust isn't required; if it must be heard, accept LoRA150's near-total intelligibility loss.
Without a LoRA
Best: neutral prompt, no LoRA → reward 0.49
GENERAL: A voice intensely expressing disgust, a revolted voice, curling with disgust, repulsed and sickened, in every breath.
