IHBench: Evaluating Post-Interruption Recovery in Voice Agents with Structured Workflows

arXiv:2606.19595v1 Announce Type: new Abstract: Voice agents deployed in structured workflows (customer service, healthcare scheduling, account management) must handle frequent user interruptions while maintaining progress through multi-step procedures. Existing benchmarks for speech-capable models focus on the timing of interruptions: barge-in detection, endpointing, and turn-taking dynamics. They leave unmeasured what happens after the interruption: does the agent resume the workflow at the correct step? Does it address the user's interjection? Does it avoid re-delivering content the user al

Why this matters
Why now

The proliferation of voice agents in critical applications requires robust evaluation beyond basic conversational turns, highlighting the urgent need for benchmarks like IHBench.

Why it’s important

Improved evaluation for post-interruption recovery drives more reliable and effective voice AI, accelerating their adoption in complex, high-stakes workflows.

What changes

The focus for voice agent development shifts from mere interruption detection to comprehensive workflow resilience, setting a new standard for performance in structured environments.

Winners
  • · AI voice agent developers
