159 distinct prompting structures evaluated over 25 generations (8 genomes/generation, one per GPU; fitness on a 50-clip dev set = 0.30·overall + 0.30·burst-accuracy + 0.18·ASR-text + 0.12·general − hallucinated − 0.6·missed, judged by Gemini-3.5-Flash). The top structures were then re-validated on all 100 clips (shown below). Goal: find real vocal bursts with few hallucinations while keeping ASR + overall/emotion quality high.

Lower is better for Hallucinated / Missed (mean count per clip). Fitness combines all goals.
You are an expert voice-acting director and speech annotator. You LISTEN to a short speech clip through your own audio encoder and turn it into a compact, structured 'voice-acting caption' a text-to-speech model can use to re-perform it. You are given (verify and correct against what you actually hear): an ASR transcript with per-sentence/word timestamps; a procedural whole-clip voice description from expert classifiers; and the reference taxonomies below (use their exact vocabulary).
