About Higgs Audio

Higgs Audio is a conversational speech system developed by The Boson AI Team. The project focuses on transitioning voice AI systems from simple text reading to expressive, natural speech. The v3 TTS model generates speech in real-time across more than one hundred languages, providing developers with zero-shot voice cloning and inline controls over emotional styling, pausing, and acoustic variations.

Our Vision

Traditional text-to-speech programs produce static vocal outputs that read sentences sequentially, often lacking the natural flow of spoken dialogue. Our goal is to supply voice models that behave as active conversational participants. By incorporating pitch alterations, pause management, and paralinguistic sounds, the speech generated by our models mirrors the natural rhythm of human conversation.

Core Model Capabilities

• Conversational Phrasing: The model automatically inserts natural pauses and adjusts intonations based on text structure.
• Vocal Customization: Through zero-shot voice cloning, the system extracts vocal fingerprints from reference audios of a few seconds.
• Direct Text Control: Inline tags let developers modify emotions and speech speeds within the target text payload.
• Broad Language Support: Accurate speech generation for over one hundred languages, spanning diverse accents and dialects.

Development & Licensing

The model weights are hosted on Hugging Face and distributed under the Apache 2.0 license, promoting open development and developer integration. We are committed to refining phonetic accuracy and reducing latency parameters to help teams deploy interactive voice applications.
