Zonos

Zonos is an open-source text-to-speech (TTS) model that delivers high-quality, natural voice generation, supports multiple languages, and features real-time voice cloning capabilities.

Features

High-Fidelity Voice Cloning

Zonos supports high-fidelity voice cloning, allowing users to generate speech that closely resembles a given sample with just 5 to 30 seconds of audio input. This feature enables users to create personalized voice content quickly.

Multi-Language Support

Zonos supports multiple languages, including English, Chinese, Japanese, French, and German. This broad language coverage makes it highly applicable for global users with diverse linguistic needs.

Emotion and Audio Quality Control

Users can fine-tune various aspects of generated speech, including speech speed, pitch, audio quality, and emotional expression (e.g., happiness, anger, sadness). This flexibility ensures that the generated speech sounds more natural and expressive.

Real-Time Performance

When running on high-end GPUs such as the NVIDIA RTX 4090, Zonos achieves low-latency real-time speech generation, with a delay of approximately 200-300 milliseconds and a real-time factor of around 2x. This makes it suitable for applications requiring rapid responses.

User-Friendly Interface

Zonos comes with a Gradio-based user interface, making speech generation straightforward and user-friendly.

Open-Source and Extensibility

Released under the Apache 2.0 license, Zonos allows researchers and developers to freely use and modify the model. This open-source nature encourages community participation and further technological advancements.

Architecture Design

Zonos follows a streamlined architecture, incorporating text normalization and phonemization, followed by DAC token prediction using transformer or hybrid models. This design ensures efficiency and scalability.
