Hume AI provides a human‑feedback layer for voice, speech, and conversational AI through a single API call. It lets teams create custom data collections tailored to specific scenarios and evaluation needs, then auto‑generates and runs simulated agent‑to‑agent or human‑to‑agent conversations to spot issues quickly. The platform measures expression in real time and offline across more than 48 emotion categories, 50+ languages, and 600+ output metrics, giving voice‑native AI teams detailed insight into how callers feel. Pre‑screened human raters deliver per‑sample scores, free‑response feedback, and aggregated analysis within hours, and a leaderboard ranks voice models by how closely they match human judgments. From study creation to results, the service handles participant screening, fraud detection, and quality monitoring, delivering fast ratings that keep pace with model development. It is used internally for evaluating voice AI and supports custom integrations and question types, with a research engineering team available to assist developers.
