The simplest AI voice workspace
One-tap RVC training turns your audio into a voice model you own —
.pth, .index and ZIP. Convert vocals with it, then separate
stems, remove noise and remove reverb, all on one page.
- You own the files. Every voice you train downloads as .pth, .index and ZIP and works anywhere RVC runs - no platform can take it away
- No installation, notebook, or local GPU
- Explore paid options if you need more
Training is working normally again. Earlier today more people were training at once than the GPUs we had available could handle, and some training jobs failed for a few hours. Apologies if yours was one of them - please try it again.

Voice training
Train an RVC voice from an audio file
Voice conversion
Convert a vocal or full song with your voice
Convert a vocal or a full song with a saved NiceVois voice or your own RVC model. Every conversion includes the normal RVC output and a NiceVois Clean Consonants version for more natural sibilance and breaths. Hear standard RVC versus NiceVois.
Voice: AIみな〜ぎ（CV 花夜みなぎ）. Example made with NiceVois Training. Results vary.
Once you've selected a voice, Auto-convert will start the conversion right away, no need to press Convert.
Check this for a full song, or for a vocal with harmonies layered over it. We split the lead out, convert only the lead, and mix it back with the untouched music and harmonies. Leave it unchecked if your file is already a clean solo vocal.
Converts ten seconds of your file at every pitch from −12 to +12, so you can hear which one suits this voice.
Choose a voice and audio on the left, then press Convert.
Credit this voice when you publish:
Voice models buzz on the sounds that carry no pitch: the s, f, sh, ch and t sounds, plus the breaths between lines. We put the original vocals back in those spots, so the singing changes voice and the consonants stay human.

A few things to know
Can I hear it before I pay?
Yes. Your first training is free, and every finished model comes with a listening proof before you decide anything.
How do the Lite allowances work?
Lite includes two training runs per paid billing month and 5 voice conversions every 24 hours, measured from when each one starts, not midnight. A conversion counts once when it starts and comes back if it fails; listening and downloads are free. Unused allowances do not carry over. Both subscriptions include unlimited vocal separation, lead/back separation, noise removal, reverb removal and Vocal Enhancer.
What does unlimited actually mean?
No minutes to count on any tool, every output included, up to 500 epochs per training run. Fair use applies. Unlimited also unlocks batch processing: drop multiple files, start once and get a separate result for each. Free and Lite process audio files one at a time. Multi-file training datasets and manual mixes are unchanged.
Do I keep my voices if I leave?
Yes. Every model is a .pth, .index and ZIP you download, and they work anywhere RVC runs.
How do I cancel?
One click from your account, no email needed. You keep everything until the end of the period you paid for, a month or a year.
What if a training fails?
You are not charged for it. A failed or cancelled run releases what it reserved, and an upload that never arrives does not spend your free run.
Do I need an account to pay?
No. Pay with any email. Sign in with that same email on any device and everything you paid for is there.
What happens to my audio?
It is processed for your job and never shared. New trainings keep your original recordings as a private dataset ZIP, plus an MP3 listening preview. Your dataset follows your voice's retention: paid runs stay until you delete them; free runs are kept for 7 days. Older voices may only have the MP3 listening copy. Temporary training files are removed after validation.
Who sees my card?
Lemon Squeezy, the merchant of record. NiceVois never sees card details, and tax is handled at checkout.

Persistent cloud storage
Your model library
Your voice models are files you own. Download them once and no platform can take them away.
Your model files and private MP3 listening preview remain available after closing the browser. New trainings also keep the original recordings in a downloadable dataset ZIP. Paid voices and their saved datasets stay until you delete them. Free voices and their saved datasets are kept for 7 days; download them before then. Older voices may only have the MP3 listening copy. Temporary training files are removed after validation.

Simple by design
Drop a file, press once, download the result
No notebook, commands, local setup, or GPU. Every tool on this page works the same way, and each one runs on its own - you never have to train a voice to use the others.
- 1Choose your tool
Train a voice, convert a vocal or full song, split stems, remove noise, or remove reverb.
- 2Drop your audio and press once
NiceVois runs it on a cloud GPU. You can close the page; training and conversion keep going.
- 3Download the files
Stems, cleaned audio, converted vocals, or a trained voice as .pth, .index and ZIP - yours to keep.
Your files, not ours
Everything you make here is yours to keep
NiceVois is not a hosted voice platform. A trained voice is a file - .pth, .index and a ZIP - that you download once and use anywhere RVC runs. Cancel, leave, or forget about us, and it still works.
- PortableStandard RVC v2 files. They load in Applio, RVC WebUI and any runtime that reads a .pth - not only here.
- Not tied to an accountThe subscription pays for the work. It is never the price of keeping your own files.
- Not at a platform's mercyWhen Weights.gg shut down, hosted models went with it. A file on your own disk cannot be shut down.

About NiceVois
Common questions
Common questions
Common questions
Common questions
What can NiceVois do?
Five things, all on this page: train a voice model from your audio, convert a vocal or a full song with a voice, split a song into vocals and instrumental, remove noise from a recording, and remove reverb from a vocal.
Do I own the model?
Yes. Every voice you train is delivered as a portable .pth and .index that you download and keep. They load in any RVC v2 runtime - Applio, RVC WebUI and others - and keep working whether or not you keep a NiceVois account or subscription. Nothing is hosted-only.
Do I have to train a voice to use the other tools?
No. Both separators, noise remover and reverb remover take any audio file and need no voice model. Conversion needs a voice - either one you trained here or your own .pth you upload.
What does training look like?
Upload your audio, choose the epochs, name your model, and press Start Training. NiceVois handles everything else and returns a downloadable .pth, matching .index, and complete ZIP.
Is this literally converting audio into a .pth file?
It is training an RVC voice model from the audio. A .pth is the resulting model-weight file, so the operation requires dataset preparation and GPU training rather than a simple format conversion.
Which audio formats can I upload?
Every tool accepts WAV, MP3, FLAC, M4A, and OGG. For training, clean dry voice audio with minimal background sound produces the most reliable result.
How much audio should I use?
Two to fifteen minutes of clean, single-speaker audio is the practical range, and recordings shorter than one minute may not produce a reliable model. NiceVois shows an exact quote from the total audio length and epochs before training starts.
Do I need an NVIDIA GPU or local RVC installation?
No. Training runs on an external cloud GPU. Once training has started, you can close the page or shut down your computer and return later.
What can I download?
You can download the named .pth by itself, the .index by itself, or a ZIP package containing both. When available, an early inference-ready checkpoint can also be downloaded while the final run continues.
How long are beta files stored?
Free-training models, saved datasets and listening previews are available for seven days. Paid models and their saved datasets remain while your account exists, unless you delete them. New trainings save the original recordings in a downloadable dataset ZIP; older voices may have only an MP3 listening copy. Temporary training files are removed after validation. Check the displayed expiry date for a free voice.
