Metric: Mean ROUGE-L F1 (%, 0-100) of the predicted against the transcribed real next utterance; next-utterance anticipation: given the interviewer's question and up to 16 video frames of the speaker's reaction, the model writes the speaker's next answer, zero-shot with one shared prompt (temperature 0.7), on the cross-scenario protocol on IEMOCAP adapted to the task (4,113 turns of acted and improvised dyadic dialogue); higher is better.
