The next-generation multilingual text-to-speech model
Hume is a research lab and technology company. Our mission is to ensure that artificial intelligence is built to serve human goals and emotional well-being.
Hume AI offers tiered pricing from free ($0) to enterprise custom plans, with SOC 2 Type II, GDPR, and HIPAA compliance available at higher tiers. Usage-based overage pricing ($0.05–$0.15 per 1,000 characters) allows cost-effective scaling, and team collaboration features support organizational growth.
Octave 2 provides unlimited voice cloning and creation across all paid tiers, allowing developers to design custom voices using descriptive prompts or clone from audio samples. This enables realistic, personalized voice experiences for games, virtual characters, and interactive applications.
Octave 2 is a closed-source LLM text-to-speech system with voice design, voice modulation, voice cloning, and voice conversion capabilities. It enables developers to create expressive speech synthesis that understands context and emotion, allowing applications to respond with appropriate tone and prosody rather than robotic speech.
Hume AI's Expression Measurement API complements Octave 2 by analyzing 48+ emotions and 600+ voice descriptors across 50+ languages. Users can measure facial expression, speech prosody, vocal bursts, and emotional language with pay-as-you-go pricing, enabling sentiment analysis and emotional intelligence insights.
Octave 2 integrates with Hume's Empathic Voice Interface (EVI) for speech-to-speech interaction. EVI provides real-time voice conversation with interruptibility, back-channeling, and expressive instruction following, enabling natural dialogue that responds to user emotion and vocal cues.
