Hume AI has raised a $50 million Series B round led by EQT Ventures and joined by Union Square Ventures, Nat Friedman & Daniel Gross, Metaplanet, Northwell Holdings, Comcast Ventures, and LG Technology Ventures. The company is also launching its Empathic Voice Interface (EVI), a conversational AI with emotional intelligence that uses vocal tones to understand when users finish speaking, predict their preferences, and optimize responses for satisfaction over time. EVI is powered by a new form of multimodal generative AI called an empathic large language model (eLLM) developed by Hume.
