• Expression Measurement API: Analyze expression across face, voice, and language to quantify emotional states.
• Conversational Voice: Full developer platform for deploying emotionally intelligent voice agents with flexible prompts and voice modulation.
• TTS Creator Studio: Tools to generate and edit long-form audio content.
• Developer Platform & API: Access to APIs, documentation, playground, and a community for integrating Hume’s voice capabilities into applications.
• Research & Ethos: Emphasis on human well-being with The Hume Initiative guidelines for empathic AI.
• Multi-Modal & Multilingual: Support for diverse voices, tones, and accents, with dynamic emotion control and multilingual capabilities (EVI 2).
• Real-Time Voice Modulation: Fine-grained control over voice properties such as pitch, femininity, nasality, and cadence.
• Prompts & Voices Library: A gallery of predefined voices and prompts for rapid prototyping and customization.
• Studio-Grade Outputs: Generate high-quality audio suitable for podcasts, voiceovers, audiobooks, and more.
• Integrations & API Access: API keys, usage monitoring, documentation, and developer resources to embed capabilities into your apps.
• Safety & Alignment: Guidelines and best practices to ensure responsible use of empathic voice technologies.
