How to Get Started with Applio: From Zero to Your First Voice Conversion

Updated

Applio is a free, open-source AI voice conversion suite that runs on Windows, macOS, and Linux (or in the cloud). To go from zero to your first conversion, you follow three steps: download the app, pick or train a voice, then convert your audio. The whole path is designed so you can start with a community voice model and skip training entirely on your first run.

Step 1: Get Applio

Download the standalone Desktop app, or choose the classic Gradio WebUI if you prefer the browser-based interface. Both are listed on the official site, and Applio Desktop is now available as a dedicated app.

  • Desktop app — a standalone install for a native experience.
  • Gradio WebUI — the classic interface, useful if you want to run it in a browser or in the cloud.

Applio is MIT licensed, so you can use, modify, and redistribute it for personal projects, research, or commercial work. No account is needed, and the project states it collects no telemetry — everything runs locally on your machine.

Step 2: Pick a Voice or Train Your Own

You have two options here, and for a first conversion the faster one is to use an existing model.

  • Use community-shared voice models — browse and download ready-made models, then skip straight to conversion. This is the recommended path when you just want to see the tool work.
  • Train your own voice — bring your own audio dataset and build a custom model. Applio's training flow is: pre-process, extract, train, and export.

If you plan to train, the Audio Analyzer is worth using first. It checks your dataset's audio health and readiness before you commit time to training, which helps you catch problems early.

Step 3: Convert Your Audio

With a model selected, transform songs, speech, or microphone input. Applio supports high-fidelity conversion and real-time inference, so the same tool covers both offline files and live use.

  • Voice Conversion — convert any audio into another voice using a ready-made model. You can tune pitch, clean, upscale, and batch-process files.
  • Real-Time Voice — change your voice live with low-latency inference, aimed at songs, streams, and calls.
  • Text-to-Speech — generate speech from text and run it through your voice models.

You can test the workflow in the Playground before committing to a full setup.

What Else Applio Includes

Beyond the basic three steps, the suite ships with tools that become useful once you're past your first conversion:

Feature What it does
Voice Blender Blends multiple voice models into one new voice, with control over each contributor
Model Training Trains a voice from your dataset through pre-process, extract, train, export
Audio Analyzer Prepares datasets and checks audio health before training
Text-to-Speech Generates speech from text, then routes it through your voice models

Common Questions Before You Start

Do I need an account? No. Applio states no accounts, no paywalls, and no telemetry are required.

Can I use it commercially? The MIT license permits use, modification, and redistribution for personal, research, or commercial work.

Which platform should I choose? Windows, macOS, and Linux are all supported, plus a cloud option. Pick the Desktop app for a standalone experience or the Gradio WebUI if you prefer running it in a browser.

What if I don't have a voice model? Start with community-shared models, then train your own once you know the conversion flow works for you.
