Simulate realistic users to test voice and chat agents
Evaluate voice AI conversations and identify where systems need improvement.

Hume AI provides tools for measuring and improving voice AI systems. Its evaluation platform turns conversation data into test scenarios and examines aspects such as timing, interruptions, tone, expression, and contextual responses. Teams can use these measurements to investigate failures that are not obvious from a transcript or task completion result alone.
The workflow includes generating tests, stress-testing systems, diagnosing weaknesses, and validating changes. It supports work on speech generation, recognition, and conversational agents, with benchmarks for comparing systems under realistic conditions. Expression APIs provide another way to incorporate measurements into a development or evaluation pipeline.
