What is Hume AI?
Hume AI builds voice AI grounded in emotion science, including expressive text-to-speech, a voice interface for conversational agents and APIs that measure more than 600 dimensions of vocal and facial expression in 50+ languages. Its VoiceEQ platform evaluates how voice systems perform with real users.
VoiceEQ turns your conversation data into targeted test suites, stress-tests a voice system, diagnoses why conversations fail and validates fixes. It scores dimensions people notice, such as timing, tone, expression, interruptions and accents, and Hume publishes benchmarks comparing speech-to-speech and TTS models.
Developers can also use Hume's own models, including the Octave text-to-speech model and the Empathic Voice Interface for building voice agents, through its API. The company draws on more than ten years of emotion research and over 100 million speech samples.
