Common questions
What is an AI voice changer?
An AI voice changer converts a recorded voice with a different voice model while following the original words, melody and timing. NiceVois uses RVC voice-to-voice conversion for singing and speech; it does not generate a song or read typed text.
Can I use it without training a voice?
Yes. Open Choose a voice and switch to NiceVois voice library. These voices are used with their creators' permission. Each voice has its own credit and conditions; commercial use is allowed only where that voice explicitly permits it. Library model files cannot be downloaded.
Is the voice changer free?
Your account includes five free voice-conversion download minutes, and listening is free. Conversion downloads use a separate allowance from the free separators. Additional downloads have paid options; an active Unlimited subscription includes unlimited conversion under the fair-use terms.
Can I change the singer in a full song?
Yes. Select Separate the stems first before converting a full song. NiceVois separates the lead vocal, backing vocals and instrumental, converts the lead, then returns a mixed cover and the separated parts. The original instrumental and backing vocals stay in the mix.
Is this a real-time voice changer for calls or games?
No. NiceVois changes uploaded audio files. It does not change your live microphone in Discord, calls or games. Upload your recorded singing or speech, convert it and download the result.
How is voice changing different from voice cloning?
Voice cloning trains a reusable voice model from permitted recordings. Voice changing applies an existing model to another recorded performance. If you want to create your own voice model first, use the AI voice cloning for singing page.
