New method suppresses spurious speech in full-duplex LLMs

By PulseAugur Editorial · [1 sources] ·

Researchers have identified and addressed an issue in full-duplex speech LLMs where models like Moshi and PersonaPlex inappropriately initiate speech during prolonged user silence. The problem stems from a sudden spike in speech probability, not repeated sampling. A new inference-time method was developed to suppress these spurious onsets by evaluating whether the model's response would change if user input were muted, successfully eliminating all tested spurious onsets without affecting genuine responses. AI

IMPACT Introduces a real-time, retraining-free method to improve the reliability of full-duplex speech LLMs.

    Causal Analysis and Mitigation of Spurious Onsets in Full-Duplex Speech LLMs

    arXiv:2609.13445v1 Announce Type: new Abstract: Speech-to-speech LLMs like Moshi, and its derivative PersonaPlex, can listen and speak concurrently through full-duplex generation. However, they can begin speaking inappropriately during prolonged user silence: under digital-zero i…
