For free AI voice cloning that can turn a vocal performance into a sung cover, start with Applio or RVC WebUI if you can work with local software; try Vocalize or Humlo for a simpler web or iPhone route. “Free” varies: some options are open-source, while others offer a small trial or free-to-try access. VOCALOID6 is included for its voice-style replication, but its free access is a time-limited trial.
What Free Singing Voice Cloning Needs
Singing voice cloning usually means converting an existing vocal performance into another voice. That is different from generating a sung melody from lyrics and notes. For a cover, the source needs a clear vocal performance; the model then changes its vocal character while the melody and timing come from that performance. Instrumental separation, pitch correction, and mixing may be separate steps, depending on the tool.

A useful starting workflow is to choose a short, clean vocal passage, convert it with a model you have permission to use, then listen for pitch stability, consonants, breaths, and whether the voice sits naturally in the track. For example, you might convert your own dry chorus into your own trained model, or make a test cover from a vocal recording you are authorized to use. Do not assume a tool handles instrumental removal or produces a finished mix unless its listing says so.

The Best Free AI Voice Cloners For Singing
1. Applio — Best Free All-Round Voice Conversion
Applio is the strongest starting point if you want a free voice-conversion suite that can handle uploaded audio or real-time conversion. It supports custom model training and voice-model blending, with batch inference, exports, TTS, and CLI automation. It runs on Windows, macOS, Linux, and Colab, and its site says no account is needed.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
For a cover, the practical route is to prepare a vocal recording, train or select an authorized model, convert the vocal, and then mix it with the backing track. Applio says it can be used, modified, and redistributed for personal projects, research, or commercial work; check the terms for any model and source audio you use. Its workflows depend on voice models, and CLI or self-hosting options may suit technical users better.
2. RVC WebUI — Best For Hands-On Local Control
RVC WebUI is a free, self-hosted toolkit for users comfortable installing software and managing models. Its directory listing describes real-time and offline conversion, single- and multi-speaker inference, training, model fusion, pitch controls, retrieval, batch processing, and WAV, FLAC, MP3, and M4A exports.
A basic cover workflow is to install the toolkit, train or load a voice model you are allowed to use, convert a vocal part, and export it for mixing. The project notes several hardware-dependent setup paths, so check its current instructions for your system before starting. Its repository states an MIT license for the project and related cited libraries; that does not establish rights to a trained voice or the recording you convert.

3. DDSP-SVC — Best Open-Source Singing-Specific Project
DDSP-SVC is explicitly a singing voice conversion project, making it a close match when the goal is to change the voice in an existing sung performance. Its project description says its training and synthesis have lower hardware requirements than SO-VITS-SVC and that real-time voice changing uses significantly fewer resources than SO-VITS-SVC, though probably slightly more than the latest RVC.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteExpect a technical setup: the project lists a working Windows combination of Python 3.11, CUDA 13.0, Torch 2.9.1, and Torchaudio 2.9.1. Treat those as the stated configuration, not a guarantee for every computer. The project asks users to train only on legally obtained authorized data and not use models or synthesized audio for illegal purposes.
4. Vocalize — Best Small Web Trial For AI Covers
Vocalize offers three credits when you sign up, with no card required, so it is useful for a small initial trial rather than ongoing free use. It supports custom voice cloning and RVC voice training; inputs include audio, YouTube links, and text-to-speech. The company says a cover takes 10 to 60 seconds depending on song length, because it separates, converts, and remixes vocals across the audio.

Use a short authorized source first, then judge the converted vocal before spending credits on a full song. The directory says there is no ongoing free plan and commercial use is restricted. Check the vendor’s current terms and pricing before relying on a cover for anything beyond a personal experiment.
5. Humlo — Best iPhone Option For A Personal Voice
Humlo is free to try without a credit card and is listed for iPhone running iOS 16 or later. It says a personal voice model can be trained from a 30-second recording, then used with a track to create a singing video. The site names styles and genres including pop, R&B, hip-hop, indie, electronic, rock, Latin, K-pop, country, and Afrobeats.

This is a different workflow from converting a recorded vocal: start with text or lyrics and a custom voice, then generate singing. The site says commercial use is available on any paid plan, so do not infer commercial rights from free access. Check the current plan terms and voice permissions before publishing.
8. VOCALOID6 — Best Free Trial For Building A Song From Melody And Lyrics
VOCALOID6 is not an ongoing free option: it has a 31-day trial with all features, then a listed one-time price from $225 before tax. It is relevant because it can import vocal data to replicate a singing style and can generate singing from melody and lyrics in Japanese, English, and Chinese with a single voicebank. It runs on Windows and macOS.
Use the trial to explore whether its melody-and-lyrics workflow fits your song, or to try importing vocal data to replicate your own style. Its voice-style replication is distinct from changing the identity of an arbitrary finished vocal recording. Check the vendor’s site for current purchase terms and the conditions attached to any imported voice data.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Voice Consent And Cover Rights
Clone your own voice or get clear permission from the person whose voice is being modeled. A voice model and a song recording raise separate permission questions, and a tool’s free tier does not establish permission to use either in a release. Read each platform’s current terms for uploads, generated covers, and commercial use. Spotify said in 2025 that vocal impersonation is allowed only when the impersonated artist has authorized it, and in 2026 announced an AI Persona badge for artist identities that may be AI-generated rather than a real person. Spotify’s 2025 policy announcement and its 2026 AI Persona announcement describe those platform policies.
