Hume AI

Hume AI offers a conversational AI voice API that can measure, interpret, and generate empathic responses to human emotional expressions. Their flagship Empathic Voice Interface (EVI) uses an empathic large language model trained on millions of interactions to provide applications with nuanced emotional intelligence capabilities like interpreting vocal tones, generating emotionally-aligned responses, managing conversation flow, and coherent text-to-speech output. The Expression Measurement API detects subtle vocal, facial, and behavioral cues conveying emotion from audio, video, and images. You can try out a demo version of Hume AI by clicking the “Speak To It” button on the homepage (a microphone is required.)
