About Hume AI

Deep Dive with Clara AI

Hume AI introduces Octave, the first voice-based large language model (LLM) built for text-to-speech (TTS). Unlike traditional systems, Octave understands context, predicting emotions, cadence, and vocal nuances to deliver highly expressive AI voices. Users can create any voice imaginable by providing a prompt or script, customizing emotional delivery and speaking style with natural language instructions. Perfect for podcasts, audiobooks, and voiceovers, Octave gives creators total control over voice expression, enabling unmatched flexibility and creativity in audio content. Powered by Hume AI’s advanced technology, Octave integrates seamlessly into applications through a streaming API, redefining how voice technology is used. It marks a new era for expressive, context-aware AI voices, offering precision and adaptability. Additionally, the Empathic Voice Interface (EVI) complements Octave by capturing detailed conversation histories, allowing developers to analyze past interactions and measure expression alongside language. With Octave, Hume AI is transforming TTS, making emotionally rich, context-driven voice generation the new standard.
