About Hume AI

Hume AI is an advanced, emotionally intelligent Voice AI platform built for creators, developers, and enterprises. Leveraging decades of research, Hume AI offers a suite of groundbreaking models designed to understand and reproduce human emotion. Its core products include Octave, a next-generation text-to-speech model that generates highly expressive, natural speech, and the Empathic Voice Interface (EVI), an instructible speech-to-speech foundation model with an ultra-low latency of 250ms. Hume's platform detects over 600 tags of emotions and voice characteristics, enabling unmatched realism. Users can generate custom voices simply by describing them in natural language, clone existing voices instantly from mere seconds of audio, and maintain consistent voice identities across more than 100 languages. Through granular acting instructions, creators can direct the AI to whisper, shout, or speak with sarcasm. Whether for building multi-character audiobooks, studio-quality podcast dialogues, expressive video voiceovers, or highly empathetic conversational agents, Hume AI provides a comprehensive API and SDKs (TypeScript, Python, .NET, Swift) to seamlessly scale emotionally intelligent audio applications.
