Description
Higgs TTS 3, developed by Boson AI, is an advanced text-to-speech model designed to transform text into expressive conversational speech. It supports over 100 languages, achieving single-digit word error rates in 85 of them, making it suitable for polished, production-quality applications. The model is particularly beneficial for digital creators, allowing them to produce and monetize content such as podcasts, videos, and social media posts for free under the Creator Use Grant. This grant requires attribution to Boson AI's Higgs Audio.

The model's architecture includes a 4 billion parameter autoregressive decoder, which processes interleaved text and audio tokens. It uses the Higgs Tokenizer to encode audio into eight codebooks at 25 frames per second, which are then mapped to backbone hidden states through a multi-codebook fused embedding. The output codes are decoded back to waveform, providing high-quality audio output.
Higgs TTS 3 offers extensive control over the generated speech, including emotion, style, prosody, and sound effects. Users can insert control tokens mid-utterance to adjust these parameters, allowing for nuanced and dynamic speech synthesis. The model also supports zero-shot voice cloning, enabling users to replicate voices with high fidelity.
The model is released for research and non-commercial use under the Boson Higgs TTS 3 Research and Non-Commercial License. Commercial use, such as embedding the model in a product or reselling it, requires a separate license. The model prohibits unethical uses like non-consensual voice cloning, impersonation, and fraud.
Higgs TTS 3 is evaluated on various benchmarks, consistently outperforming previous versions and other models in terms of word error rates and overall quality. It is available for integration via the Boson AI API, and users can serve the model using the SGLang-Omni production stack for efficient deployment.
