A new study published on arXiv investigates the reliability of multimodal signals for understanding conversational states like cognitive load and power dynamics. Researchers developed a three-dimensional evaluation framework to assess predictive accuracy, cross-task generalizability, and test-retest reliability using interactional, acoustic, and linguistic features from dyadic conversations. The findings indicate that while linguistic features are predictive, they lack generalizability across tasks, and acoustic features are more indicative of vocal characteristics than conversational state when speaker identity is controlled. Interaction features emerged as the most reliable signal for cognitive load, but predicting conversational power role remained challenging. AI
