Resemble AI has publicly released Dramabox, a new text-to-speech (TTS) model designed for generating expressive and high-quality audio. The model's standout feature is its ability to perform one-shot voice cloning, replicating a speaker's voice from just a single short audio clip.

Under the hood, Dramabox employs a diffusion-transformer architecture. According to the company, this approach is built upon their LTX-2 flow-matching audio technology, which enables fine-grained control over the generated speech. This allows the model to produce not just clear narration but also audio with emotional nuance and expressiveness, a key challenge in speech synthesis.

## Availability and License

Developers and researchers can access the model weights and inference code on the [Hugging Face Hub](https://huggingface.co/ResembleAI/Dramabox). It's important to note that Dramabox is released under a custom Community License. This license permits non-commercial use and research, but requires a separate commercial license for any business applications.

The release of Dramabox provides the open-weights community with a powerful tool for creative and research-oriented audio projects. Its combination of a modern architecture and effective voice cloning makes it a significant new entry in the landscape of publicly available TTS models, offering a high-quality foundation for non-commercial applications.
