A new open-source model for generating speech from text has been released by a group called OpenMOSS. Named [Soprano-1.1-80M](https://huggingface.co/ekwek/Soprano-1.1-80M), the model is exceptionally compact at just 80 million parameters and is available under the permissive Apache 2.0 license.

What sets Soprano apart is its foundation. The model adapts the architecture of Qwen3, a family of models primarily known for large-scale text generation. Applying a modern large language model (LLM) architecture to the specialized task of text-to-speech (TTS) represents an increasingly common strategy for leveraging the power of these advanced designs across different modalities.

The model's small size is a significant advantage, making it suitable for developers who need to run speech synthesis on consumer-grade hardware or in resource-constrained environments. By combining this efficiency with an open license, Soprano lowers the barrier for integrating custom, high-quality voice generation into a wide range of applications, from accessibility tools to creative projects.

Soprano-1.1-80M is available for download and experimentation now from the Hugging Face Hub.
