Ranked Free AI Voice Cloners For Singing
1. Applio — Best Overall Free Voice Conversion
Applio is a free, open-source voice conversion suite for Windows, macOS, Linux, and Colab. It supports real-time and uploaded-audio conversion, custom model training, voice-model blending, batch inference, exports, text-to-speech, and command-line automation. It needs a voice model for conversion, so it is best understood as a way to convert a vocal into another voice, rather than a tool that writes a finished song from a text prompt.

7. RVC WebUI — Best For Detailed Local RVC Control

For a singing conversion, the workflow is to set up the project, train or select an authorized voice model, adjust pitch and retrieval settings, then compare an offline render with the original vocal. The project page references MIT licensing, but that alone does not settle rights for recordings, model data, voices, or covers; check the repository and relevant terms before distributing output. RVC WebUI
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How To Choose For A Singing Voice
Voice cloning for singing has a different practical target from ordinary text-to-speech: the converted vocal needs to follow a melody and phrasing while remaining usable in a mix. A tool that converts an existing vocal is a closer fit when you already have a sung performance; a text-to-singing workflow is useful when you want to enter lyrics and generate a vocal. The listed products establish different parts of that workflow, so confirm that your chosen tool accepts the input you have and provides the output you need.
- For a free local or flexible setup: begin with Applio; consider DDSP-SVC or RVC WebUI if you want an open-source project and can handle technical setup.
- For a quick phone experiment: Humlo is the option here explicitly built around recording your voice on iPhone.
- For a browser trial: Vocalize states a three-credit signup allowance; check whether that trial covers the length and type of cover you want.
- For stems or a custom model workflow: TopMediai lists custom training and separate vocal, instrumental, and full-mix exports, but its free limits are not stated.
- For lyric-driven generation: Uberduck lists singing from text, but verify whether the free access includes the custom voice and singing features you need.
Voice And Song Rights To Check Before Sharing
Use your own voice or get permission from the person whose voice you want to reproduce. Also check each service’s terms for the source song, model data, covers, and commercial use; the tools do not establish one shared set of rights. Spotify’s September 2025 policy announcement said vocal impersonation on its service is allowed only when the impersonated artist authorized it, and it supports AI disclosures in credits. Read the report on Spotify’s policy announcement.
