by Hume
Hume AI is a research lab and technology company building the first empathic large language model (eLLM). Their core offering is an API platform that provides AI models capable of measuring and responding to nuanced human emotional expression from vocal tones, facial expressions, and language. This goes beyond sentiment analysis to capture the full spectrum of non-verbal communication, enabling developers to create applications that understand and adapt to human emotion in real-time.

The platform features the Expression Measurement API for analyzing vocal bursts (like laughter and sighs), prosody (tone of voice), and facial expressions. The Empathic Voice Interface (EVI) is a real-time, voice-to-voice interface that can hold natural conversations, responding with appropriate emotional resonance. Hume's models are trained on a massive, proprietary dataset of human expression, aiming to align AI with human well-being.

Hume's technology is designed for developers, researchers, and enterprises looking to build more natural, engaging, and emotionally intelligent applications. Use cases span customer service, mental health tech, interactive media, market research, and human-computer interaction studies.
