Fish Speech: An In-Depth Introduction
Fish Speech is an innovative open-source project that brings advanced text-to-speech (TTS) capabilities to a wide audience, allowing for seamless voice cloning across multiple languages. Here is a detailed overview of the project's features, functionalities, and contributions.
Features of Fish Speech
-
Zero-shot & Few-shot TTS: Fish Speech empowers users to perform high-quality text-to-speech conversions by using as little as a 10 to 30-second vocal sample. This makes it easy to clone voices with minimal input. Detailed instructions for optimizing voice cloning can be found in their Voice Cloning Best Practices.
-
Multilingual & Cross-lingual Support: One of Fish Speech's standout features is its ability to handle text input in various languages without requiring users to navigate language settings manually. It currently supports English, Japanese, Korean, Chinese, French, German, Arabic, and Spanish, making it a versatile tool for global communication.
-
No Phoneme Dependency: Unlike some TTS models that rely heavily on phoneme inputs, Fish Speech does not require phonemes, demonstrating strong generalization abilities across different language scripts.
-
High Accuracy: Fish Speech achieves an impressively low Character Error Rate (CER) and Word Error Rate (WER) of around 2% for texts up to five minutes long in English, ensuring clarity and precision in output.
-
Speed Efficiency: Benefiting from fish-tech acceleration, Fish Speech operates efficiently with a real-time factor of approximately 1:5 on an Nvidia RTX 4060 laptop and 1:15 on an Nvidia RTX 4090, offering fast processing times for users.
-
Web User Interface: The project includes a Gradio-based web UI, offering a user-friendly experience across various web browsers such as Chrome, Firefox, and Edge.
-
Graphical User Interface (GUI) Inference: The project also supports a PyQt6 graphical interface that works smoothly with the API server, available on Linux, Windows, and macOS systems. More details can be seen on their GUI page.
-
Deployment Flexibility: Fish Speech is designed for easy deployment, providing native support for servers on Linux, Windows, and MacOS, while minimizing speed losses.
