Can You Say This for Me? Speaking Up by Proxy in Co-Located Discussion

Read the original on arXiv AI →

SecondVoice is a mixed‑reality system that lets participants speak up in co‑located discussions via an embodied virtual proxy, separating the content of a point from the speaker’s identity. Users input their intent through a structured process, and the system reformulates and vocalizes it into the conversation. In a study with 16 participants, the proxy channel led to more points being voiced than an anonymous text board and sparked multi‑turn engagement that the text board did not elicit.

Speak for Me: Giving LLMs the Situational Awareness to Participate in a Meeting

The paper introduces CAPA, a Collaborative Agent Predictive Architecture designed to give large language model (LLM) agents situational awareness in online meetings. CAPA uses a Perceiver to update meeting state, a Predictor to forecast conversation flow, a Controller to decide speaking actions, and a Generator to phrase contributions. Evaluated on 137 AMI meetings, CAPA reduces the silence rate from 51.4% to 2.5%, doubles credited recovery, and maintains low hallucination, demonstrating that structured state tracking is key to effective delegation.

Speak for Me: Giving LLMs the Situational Awareness to Participate in a Meeting

The paper introduces CAPA, a Collaborative Agent Predictive Architecture designed to improve large language model (LLM) participation in online meetings. CAPA tracks meeting state with a Perceiver, predicts conversation flow, decides when and what to speak, and generates contributions in the participant’s style, all while being calibrated by judges. In experiments on 137 AMI meetings, CAPA cuts the LLM’s silence rate from 51.4% to 2.5%, doubles credited recovery, and maintains low hallucination.

Do LLM Agents Mirror Socio-Cognitive Effects in Power-Asymmetric Conversations?

The paper investigates whether large language models (LLMs) replicate socio‑cognitive effects of power asymmetry observed in human communication. By assigning high or low status personas to LLMs in simulated multi‑turn dialogues across diverse professions, the study measures language coordination, pronoun usage, persuasion success, and compliance with unsafe requests. Results indicate that LLMs exhibit key power‑related socio‑cognitive behaviors, though with nuances and variability, linking these simulated interactions to both desirable and unsafe outcomes.
