About
Hume builds voice AI models with a focus on emotional intelligence. The product line includes TADA, an open-source LLM text-to-speech system that streams text and audio together to reduce hallucinations and latency, plus Octave (closed-source TTS) and EVI, a speech-to-speech system. They also ship a Human Feedback API and Study Runner for running evaluation studies against a vetted participant pool.
Alongside the models, Hume publishes open source datasets and evaluation APIs so other teams can embed emotional intelligence into their own voice models. Coverage spans 50+ languages, 48+ emotions, and 600+ voice descriptors, drawn from research the company says identified over 30 emotion dimensions.
Stated mission: "Building AI with emotional intelligence to create technology that truly understands humanity." The team frames its work around the idea that AI should enhance human connection rather than replace it.
