Google DeepMind licensing deal (2026). EVI supports 11 languages. Projecting $100M revenue. Founded 2021, NYC. ## Company Overview Hume AI is an empathic AI company founded in 2021 with the mission of building AI systems that understand and respond to human emotional expression. The company was founded by Alan Cowen, a former Google researcher who pioneered the scientific study of emotional nuance in AI, and is built on the thesis that AI systems capable of perceiving emotional cues will be safer, more useful, and more human-centered than emotionally oblivious alternatives. Hume's research heritage gives it a defensible scientific moat in a space where most competitors treat voice AI as a purely acoustic engineering challenge.\n\nHume's flagship product is EVI (Empathic Voice Interface), a conversational voice AI API that processes not just the words spoken but the emotional tone, prosody, and expression of the speaker to generate more contextually appropriate and emotionally resonant responses. EVI supports 11 languages and is used by developers building voice agents, mental health applications, customer service systems, and AI companions. In 2026, Google DeepMind entered a licensing agreement with Hume to incorporate its emotional intelligence technology — a landmark validation of Hume's foundational research. The developer platform has attracted more than 100,000 users.\n\nHume AI is projecting $100 million in annual revenue and continues to grow its developer base through a combination of API pricing and enterprise agreements. The Google DeepMind licensing deal provides both recurring revenue and industry validation that Hume's emotional AI technology is considered best-in-class by one of the world's most credible AI research organizations. As voice AI proliferates across consumer and enterprise applications, Hume's emotional intelligence layer is increasingly seen as essential infrastructure for building AI experiences that feel natural and trustworthy. ## Frequently Asked Questions ### What is Hume AI? Empathic Voice Interface detecting and responding to emotions in real-time via voice across 11 languages. ### What is the DeepMind deal? Major licensing agreement (early 2026). Founder joined DeepMind, Andrew Ettinger became CEO. ### Who uses Hume? 100K+ developers across healthcare, education, automotive, robotics, and customer support. ### What languages does Hume support? English, Japanese, Korean, Spanish, French, Portuguese, Italian, German, Russian, Hindi, Arabic. ### What is the science behind Hume AI's emotion detection? Hume AI's emotional intelligence is trained on large datasets of human speech labeled with emotional states. The system detects prosodic features — pitch, rhythm, tempo, breathiness — and vocal quality markers that correlate with emotional states like stress, excitement, frustration, and calmness. The model processes these features in real-time to generate an emotional state estimate that the AI can factor into its responses. ### What safeguards does Hume AI have against emotional manipulation? Hume AI's models are trained to respond to detected emotions in ways that support user wellbeing rather than exploit emotional states. Hume has published research on emotionally intelligent AI ethics and designed the EVI to avoid using emotional awareness manipulatively — for example, not exploiting frustration to push upsells or using fear detection to drive compulsive behaviors. Enterprise customers can configure appropriate emotional response policies. ### How does Hume's EVI integrate with existing voice applications? Hume AI provides a developer API with WebSocket support for real-time voice streaming, REST endpoints for batch audio analysis, and SDKs for Python, JavaScript, and other languages. EVI can be integrated into customer service platforms, mental health applications, automotive interfaces, and educational tools. The API handles speech-to-text, emotional analysis, and text-to-speech in a unified pipeline. ### What is the DeepMind licensing deal and what does it mean for Hume? Hume AI entered a major licensing agreement with DeepMind in early 2026, allowing DeepMind to use Hume's emotional intelligence models in its own AI systems. This validates Hume's technology at the highest level of AI research — DeepMind is one of the world's most capable AI labs. The deal provides significant revenue and credibility while the founding researcher joining DeepMind reflects the talent flow between frontier AI organizations. ## Tags ai-powered, saas, b2b --- *Data from geo.sig.ai Brand Intelligence Database.
