The method resolves three error types—inconsistent values, omitted slots, and audio-unsupported values—using vote, add, and swap operators restricted to specific slots, with the audio verifier providing a statistically significant gain.", "body_md": "arXiv:2609.01828v1 Announce Type: new\nAbstract: Spoken dialogue state tracking recovers slot-value pairs from speech, where ASR errors concentrate in entity values and persist across turns, making it both a generation and an editing problem. A strong per-turn text editor corrects much of this but, operating on the transcript alone, leaves three recoverable errors: a value predicted inconsistently across turns, an omitted slot, and a value the audio does not support. We present AVERT, which scores each candidate value by combining cross-turn agreement with a trained audio-conditioned verifier and resolves the three error types with three operators, vote, add, and swap, each restricted to the slots where its error is common. On SpokenWOZ, a base speech-LLM reaches 33.04 JGA, a text editor 38.34, and AVERT 40.13, without retraining either. This is in the range of a 1B end-to-end system that consumes the full spoken history (39.32), though AVERT uses two 1B decoders rather than one. The audio verifier contributes a statistically significant gain, and restricting each operator to a selected slot subset matters: removing it lets unrestricted voting overwrite correct categorical values and fall below the editor.", "url": "https://wpnews.pro/news/avert-audio-verified-adjudication-for-spoken-dialogue-state-tracking", "canonical_source": "https://arxiv.org/abs/2609.01828", "published_at": "2026-09-03 04:00:00+00:00", "updated_at": "2026-09-03 04:25:36.775373+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "natural-language-processing", "ai-research"], "entities": ["AVERT", "SpokenWOZ"], "alternates": {"html": "https://wpnews.pro/news/avert-audio-verified-adjudication-for-spoken-dialogue-state-tracking", "markdown": "https://wpnews.pro/news/avert-audio-verified-adjudication-for-spoken-dialogue-state-tracking.md", "text": "https://wpnews.pro/news/avert-audio-verified-adjudication-for-spoken-dialogue-state-tracking.txt", "jsonld": "https://wpnews.pro/news/avert-audio-verified-adjudication-for-spoken-dialogue-state-tracking.jsonld"}}
