Applio

Applio is an open-source, locally hosted AI voice conversion toolkit designed for creating, training, and deploying custom voice models. It provides a graphical user interface that simplifies complex workflows, allowing users to manage datasets, train models, and run real-time or offline voice conversion without extensive command-line interaction. Applio supports multiple state-of-the-art voice conversion backends and offers tools for preprocessing audio, extracting features, and fine-tuning models to achieve higher quality and more natural-sounding results.

Users can load and manage multiple voice models, adjust inference settings such as pitch, formant, and noise reduction, and export converted audio for use in content creation, dubbing, or experimentation. The platform is suitable for developers, audio enthusiasts, and researchers who want control over their models and data while working entirely on their own hardware. With built-in logging, model management, and configuration options, Applio helps streamline the end-to-end process of voice cloning and conversion, from raw audio to deployable models, in a single, organized environment.
