תקציר מקורי באנגליתarXiv:2609.38232v1 Announce Type: cross Abstract: Streaming spoken agents may take an external action before the available speech supports it, yet final-turn scores do not reveal whether each observed prefix supports that action. We introduce the Partial Speech Action Contract for Turn Taking in Speech Language Models (PACT-SLM), a controlled evaluation that assigns a first valid action time and measures action identity and timing separately. The primary diagnostic contains 80 paired contrast groups from four held-out semantic families and 1,600 prefix predictions across clean and 15 dB noise renderings. After correcting a mismatch between randomized branch codes and semantic labels, a refitted WavLM Base Plus probe reaches 26.03% pooled post-onset semantic-label accuracy (95% group-bootst
