arXiv:2606.11386v1 Announce Type: new Abstract: Full-duplex spoken language models (FD-SLMs) enable seamless speech interaction by allowing models to listen and speak simultaneously, yet the internal mechanism by which they coordinate listening and speaking remains underexplored. We analyze the predictive behavior encoded in FD-SLM hidden representations and find that they exhibit stream-specific predictive patterns: during listening, they preferentially predict the incoming user stream, whereas during speaking, they preferentially predict the model output stream. Building on this observation,
This development is happening now as researchers push the boundaries of AI models to achieve more seamless and natural human-computer interaction, particularly in conversational AI.
This work is important as it addresses a fundamental challenge in real-time conversational AI, enabling more natural and efficient interaction by allowing models to listen and speak simultaneously without internal conflicts.
This research potentially changes how full-duplex spoken language models are designed and optimized, moving towards more intelligent and context-aware internal processing that better distinguishes between input and output streams.

Advancements in FD-SLMs will lead to more fluid and less latency-prone AI assistants and interfaces.
Improved conversational AI could accelerate the adoption of autonomous AI agents in various sectors.
As AI interactions become indistinguishable from human ones, societal expectations for digital interfaces will significantly rise.
