That binary cannot express a third response humans use routinely: continuing to speak while incorporating what the listener just contributed. The contribution may be a missing word, a correction or a clarification. We introduce Duplex Cue, an evaluation of this [in-turn adaptation](/papers?q=in-turn%20adaptation) in [full-duplex](/papers?q=full-duplex) voice agents. Duplex Cue separates listener intent ([backchannel](/papers?q=backchannel), [collaboration](/papers?q=collaboration), or [interruption](/papers?q=interruption)) from speaker behavior: continuing unchanged, adapting within the turn, or yielding. Adaptation includes acknowledgment as well as content revision. In a single-model case study using 300 human-confirmed cues from unscripted English conversations, we compare recorded human responses with [PersonaPlex](/papers?q=PersonaPlex) continuations generated while replaying the listener's audio. We retain 208 pairs with the ongoing speaker active at cue onset and a scorable response in each condition. On the 66 collaborative pairs, recorded speakers adapt in 68.2\\% of cases, compared with 34.8\\% for [PersonaPlex](/papers?q=PersonaPlex). The model otherwise continues unchanged (42.4\\%) or yields (22.7\\%). These findings show why evaluating natural voice interaction requires measuring how an agent responds to a listener's contribution as well as whether it keeps speaking.\n\nGet this paper in your agent:\n\n`hf papers read 2609.13117` ## Don't have the latest CLI?\n\n`curl -LsSf https://hf.co/cli/install.sh | bash` ## Models citing this paper 0\n\nNo model linking this paper\n\n## Datasets citing this paper 0\n\nNo dataset linking this paper\n\n### Spaces citing this paper 0\n\nNo Space linking this paper", "url": "https://wpnews.pro/news/continue-adapt-or-yield-in-turn-adaptation-to-overlapping-speech-in-full-duplex", "canonical_source": "https://huggingface.co/papers/2609.13117", "published_at": "2026-09-14 14:10:02+00:00", "updated_at": "2026-09-14 14:47:47.732546+00:00", "lang": "en", "topics": ["artificial-intelligence", "natural-language-processing", "ai-research", "ai-agents"], "entities": ["Duplex Cue", "PersonaPlex", "Inkling-Small", "Thinking Machines"], "alternates": {"html": "https://wpnews.pro/news/continue-adapt-or-yield-in-turn-adaptation-to-overlapping-speech-in-full-duplex", "markdown": "https://wpnews.pro/news/continue-adapt-or-yield-in-turn-adaptation-to-overlapping-speech-in-full-duplex.md", "text": "https://wpnews.pro/news/continue-adapt-or-yield-in-turn-adaptation-to-overlapping-speech-in-full-duplex.txt", "jsonld": "https://wpnews.pro/news/continue-adapt-or-yield-in-turn-adaptation-to-overlapping-speech-in-full-duplex.jsonld"}}
