About Hume
Hume is a web-based evaluation platform for voice AI, speech systems, and conversational agents. It combines automated measurement with structured human judgment to assess how voice systems perform in realistic conditions, including timing, tone, expression, interruption, and contextual appropriateness beyond words and transcripts.
Users can turn real-world use cases into targeted test suites, stress-test models and agents, diagnose failures, and validate improvements. The platform provides tools to measure vocal expression across languages, prepare audio for evaluation and training, and run evaluations with trained raters through APIs.
It suits teams developing text-to-speech, speech-to-speech, speech recognition, or cascaded voice systems, as well as enterprises deploying voice agents. Example use areas described include healthcare, contact centers, financial services, and retail, where interaction quality and user experience matter.
