Song to your voice
Add the finished song and a clean recording of your voice. Press once. NiceVois trains your private voice, separates the song, converts the lead vocal, cleans the consonants, and mixes the finished track.
Voice conversion
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.

Train your voice nowCheck 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.
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.

Finished
The lead is converted into your trained voice, cleaned, and mixed back with the original music and backing vocals.
NiceVois uses the voice recording to create a private, reusable RVC model. It then separates the finished song, changes only the lead singer, restores the consonants and breaths that RVC tends to smear, and mixes the song back together.
The usual giveaway in a voice conversion is the consonants. RVC reproduces sung vowels well and smears the sharp sounds around them — the s, t and k, and the breaths between phrases. NiceVois splices those back in from the original performance, matched in level and tone to the converted voice. That single step is the difference between a cover that sounds like a person and one that sounds like software.
Your model is yours. It trains from your own clean recordings, stays private to your account, and downloads as a portable .pth and .index pair you can take anywhere. Training once is the point: the model is reusable for every song you make from then on.
Suno Voices can generate new songs with a verified voice profile. That is useful when you want Suno to create a new performance. Changing only the singer in a finished song is different: you are trying to preserve the existing timing, arrangement, and backing track while replacing the performed lead vocal.
Suno's own help center explains that an exported song contains the music and words in one file, so changing the voice in that rendered version requires stem extraction or another editing workflow. That separation step is the reason a normal voice changer cannot safely treat the full mix as one vocal.
Download the highest-quality audio file you can. Avoid repeatedly converting it between compressed formats before separation. Every watery edge or smeared cymbal created at this stage can become more obvious after the vocal is removed and rebuilt.
Use a clean clip of your own voice, or a speaker who knowingly gave permission for a reusable voice model. Dry, single-speaker audio is best. Background music, overlapping singers, strong room reverb, and heavy effects all make it harder for the model to learn the voice itself.
If you already have a private RVC .pth and matching .index, keep them together. If you do not, train the voice on NiceVois or follow the same RVC training process yourself.
The model is the reusable voice. Training prepares the voice audio, extracts pitch and voice features, learns the target voice, and packages the result as a .pth plus its retrieval .index. NiceVois keeps those files portable, so this cover workflow does not lock the model to one website.
At minimum, split the record into a vocal stem and an instrumental. A better cover keeps the lead vocal separate from harmonies and backing vocals. The lead is the part that changes voice. The instrumental and backing vocals should retain the record's stereo width and timing.
Separation is not lossless. Listen for instrumental bleed in the vocal stem, missing transients, watery high frequencies, or harmonies that were accidentally grouped with the lead. Those problems carry into the conversion if they are not caught here.
Run only the isolated lead through the RVC model. Choose the transpose in semitones so the source performance sits in the target voice's natural range. Zero preserves the source pitch; twelve semitones moves one octave.
Ordinary RVC often sounds most artificial on unpitched sounds such as s, f, sh, ch, and t, plus the breaths between lines. The NiceVois Clean Consonants stage detects those moments and restores them from the source vocal, so the vocal changes identity without turning every consonant into a metallic buzz.
Place the converted lead back over the instrumental and backing vocals. Preserve the backing track's stereo image, match the original lead-to-instrumental balance, and check the total loudness against the source record. Then listen through the full song for timing drift, clipping, missing phrases, separation residue, and sudden changes in voice identity.
The finished deliverable is the mixed cover. It is also useful to keep the cleaned isolated vocal so you can make your own mix in a DAW. NiceVois returns both and includes a vocal-level control before download.
| If you do it yourself | Managed NiceVois route |
|---|---|
| Prepare and train the RVC voice separately | Drop in the permitted voice clip or use a private model |
| Separate instrumental, lead, and backing vocals | NiceVois runs the separation chain |
| Load the model and convert the lead | NiceVois carries the trained voice into conversion |
| Repair robotic consonants and breaths | Clean Consonants runs before the remix |
| Line up, balance, and export the mix | NiceVois returns the cover and cleaned vocal |

Yes. The finished song has to be separated first, because the export contains the music and the vocal in one file. NiceVois does that for you: it splits the song, converts the isolated lead through your voice, restores the consonants and breaths, and mixes it back over the original instrumental and backing vocals.
Suno has a Voices feature for generating songs with a verified voice profile. Replacing only the singer in an already rendered song is a different production task because the exported song contains music and vocals in one mixed file.
Yes. Add the finished song and a clean permitted voice recording, then press once. NiceVois trains the voice, separates the song, converts and cleans the lead, and returns the finished cover along with the lead vocal, backing vocals, and instrumental as separate files.
Only when you have the rights required for both the voice and the song. Training or converting a voice does not grant rights to a recording or composition.
Add the finished song and a recording of your permitted voice. NiceVois handles the training, separation, conversion, cleaning, and mix as one project.
