Is AI’s next big leap understanding emotion? $50M for Hume says yes

Key Points:

  • Hume AI focuses on creating an AI assistant with emotional intelligence for chatbot integration.
  • Hume AI’s AI assistant, EVI, detects a wide range of human emotions and uses vocal cues for understanding.
  • Hume AI offers APIs like Expression Measurement, Speech Prosody Model, and Custom Models for enterprise use.


Hume AI, a startup co-founded by former Google DeepMind researcher Alan Cowen, recently secured $50 million in a Series B funding round led by EQT Ventures. The startup’s focus lies in developing an AI assistant and API that can understand and respond to human emotions, even in voice conversations. Unlike traditional text-based chatbots, Hume AI’s technology delves into vocal intonations, pauses, and other subtle cues to interpret emotions.


One of the key features of Hume AI’s offering is its Empathic Voice Interface (EVI), which claims to be the first conversational AI with emotional intelligence. The AI boasts the capability to identify 53 distinct emotions, going beyond basic feelings like happiness or sadness to include more nuanced states like admiration, craving, and shame. By tapping into a broad spectrum of emotions, Hume AI aims to enhance user interactions, customer support, and various applications across industries.


Hume AI’s technology, developed through extensive research and training on experimental data involving facial expressions and vocal bursts from diverse populations worldwide, incorporates a speech prosody model. This model allows the AI to understand vocal cues, tune, rhythm, and timbre of speech, thereby enhancing its ability to comprehend user intentions, preferences, and emotional nuances.


The startup offers Expression Measurement API for enterprises to leverage its emotional AI capabilities, including understanding facial expressions, vocal bursts, and emotional tone inferred from transcribed text. Additionally, Hume AI provides an Empathic Voice Interface API and Custom Models API for tailored emotional expression recognition in various datasets.


While the potential applications for Hume AI’s technology span areas such as health, customer service, coaching, and robotics, concerns have surfaced regarding the ethical implications and potential misuse of empathic AI. To address these issues, the startup established The Hume Initiative, a non-profit organization dedicated to establishing ethical guidelines for the responsible use of empathic AI. These guidelines aim to safeguard user well-being, prevent exploitation and manipulation, and regulate the development and deployment of empathic AI technology.


Following the unveiling of Hume AI’s EVI demo, tech industry professionals and early adopters lauded the technology for its naturalistic dialogue, sophisticated capabilities, and impressive latency. The demo showcased the AI’s advanced emotional intelligence and its potential to revolutionize human-computer interactions.


As Hume AI continues to innovate in the field of empathic AI, balancing technological advancement with ethical considerations remains a critical aspect of its mission to provide meaningful and responsible AI solutions. The startup’s dedication to promoting user well-being, fostering emotional awareness, and adhering to ethical guidelines underscores its commitment to creating a positive impact with its AI technologies.
