LibreTTS is a free, open-source, web-based Text-to-Speech (TTS) tool designed for users who need to convert text into speech with various voice options and adjustable parameters. It offers real-time preview, audio downloading, and supports long text processing, making it suitable for content creators, developers integrating TTS, and individuals needing accessible text-to-speech functionality.

How It Works

LibreTTS leverages existing TTS engines, primarily supporting Microsoft Edge TTS and OpenAI-compatible APIs. It acts as a frontend, abstracting the complexities of these services. The core advantage lies in its unified interface, allowing users to switch between and manage multiple TTS providers, including custom endpoints, from a single, responsive web application. This approach provides flexibility and access to a wide range of voices and quality settings without requiring individual integration for each service.
