What is Zonos?

Zonos is an open-source text-to-speech (TTS) tool developed by the Zyphra team, featuring two advanced 1.6 billion parameter models: a transformer and a hybrid SSM model. Released under the Apache 2.0 license, Zonos aims to provide high-fidelity, expressive, and real-time voice cloning capabilities. It addresses the challenge of generating natural and emotionally rich speech from text, supporting multiple languages with a focus on English and several major world languages. Zonos is designed for researchers, developers, and businesses seeking customizable TTS solutions with fine control over speaking rate, pitch, emotions, and voice cloning from short audio samples. Its models are trained on extensive speech datasets, enabling nuanced and high-quality audio output suitable for applications such as audiobooks, virtual assistants, and accessibility tools. The tool fits workflows that require open, flexible, and high-quality speech synthesis with an emphasis on research and innovation.
