Summary

ModeratorLM is a novel role-playing voice agent designed to improve turn-taking in real-time multi-party spoken conversations, particularly amidst dynamic floor competition. This system utilizes a speech large language model operating in a chunk-wise streaming manner, conditioning its turn-taking behavior on an explicitly assigned role. A reasoning-augmented variant further enhances its capabilities by incorporating chain-of-thought reasoning based on conversational context and the agent's role. To facilitate development and evaluation, the researchers constructed RolePlayConv, a large-scale synthetic dataset featuring diverse assistant roles in multi-party dialogues. Experimental results, conducted on both real-world meeting data and the RolePlayConv dataset, demonstrate substantial improvements: turn-taking precision increased by over 40% and recall by more than 70%, alongside a significant reduction in false-positive interruptions compared to baselines not conditioned on roles.

Key takeaway

For Machine Learning Engineers developing multi-party voice agents, you should integrate explicit role-conditioning into your turn-taking models. This approach, demonstrated by ModeratorLM's 40% precision and 70% recall improvements, significantly reduces disruptive false-positive interruptions. Consider incorporating chain-of-thought reasoning to enhance context awareness, ensuring your agents contribute more naturally and effectively in complex conversational environments.

Key insights

Role-conditioned turn-taking significantly improves multi-party voice agent performance by reducing interruptions.

Principles

• Explicitly assigned roles enhance voice agent turn-taking precision.
• Chain-of-thought reasoning improves context-aware conversational decisions.

Method
