About Hume AI
Hume AI builds voice technology that pays attention to how people sound, not only what they say. Its Empathic Voice Interface listens for tone and emotion and adjusts its own voice and responses accordingly.
Developers can use it to create assistants for coaching, wellbeing, customer care or games, and the platform also offers expressive text to speech with controllable emotion. Research on emotion measurement underlies the products.
Hume has a free tier and usage-based pricing. It is an interesting option for teams that want conversations to feel warmer and more responsive.
