Where Voice Agents Actually Break

While modern voice agents sound increasingly natural, true reliability requires mastering turn-taking, action control, and error recovery rather than just relying on accurate transcription. The article identifies critical failure modes, such as mid-action corrections and improper handling of interruptions, which can lead to incorrect tool executions and poor user experiences. To build production-ready systems, developers must move beyond transcript accuracy and implement holistic measurement disciplines that evaluate the entire real-time interaction loop.
