About Applio
Applio is an open-source AI voice conversion suite. It converts audio into another voice using ready-made voice models, and it can also train custom voice models from a user's own audio dataset. The homepage lists use cases including AI covers, live voice changes for songs, streams, and calls, and speech generated from text. It is offered as a standalone desktop app or the classic Gradio WebUI, and the homepage names Windows, macOS, and Linux, along with a cloud option.
The software is MIT licensed, and the homepage says it can be used, modified, and redistributed for personal, research, or commercial work. The homepage says no account or telemetry is required and that everything runs locally on the user's machine. It also mentions cloud use, so data handling may differ depending on how the software is run. The homepage describes Applio as free but does not list pricing details. It also says model access was changed in December 2024 to support responsible usage and community safety, without giving details on the page.
