TL;DR. This is a no-LoRA emotion — best reward comes from the plain neutral BASE prompt (0.498); both the evolved steering prompt (0.429) and every LoRA merge reduce reward. The failure mode is that steering and the LoRA collapse vocal-burst blend (0.453 to 0.27-0.33) faster than they add any emotion, and the LoRA also fights intelligibility (LoRA150 corr neg Articulation Clarity -0.82). If you must inject audible enthusiasm, LoRA150 does raise target emotion to 0.168 (shift up Triumph +0.94, Elation +0.91), but reward (0.454) still trails BASE. Recommendation: keep this emotion neutral with minimal steering.
Without a LoRA
Best: neutral prompt, no LoRA → reward 0.50
GENERAL: A voice deeply expressing hope enthusiasm optimism, a bright, hopeful voice, brimming with enthusiasm and optimism, uplifting, impossible to hide.
