IHBench: Evaluating Post-Interruption Recovery in Voice Agents with Structured Workflows
Researchers introduce IHBench, a benchmark for evaluating how voice agents recover from user interruptions while executing multi-step workflows in enterprise settings. Testing 27 model configurations reveals closed-weight models (OpenAI, Google) significantly outperform open-weight alternatives in handling interruptions, recovering 3.3x more gracefully and maintaining task completion rates.
