To convert a singing voice with AI, start with a clean recording of the vocal performance, then process it with a tool that explicitly supports singing voice conversion. Tunela is a web option for singing conversion; SoulX-Singer is a research-oriented toolkit for singing voice conversion. Conversion changes the voice character of an existing performance; it does not mean generating a new melody or replacing the singer’s timing and phrasing.
Choose A Singing Voice Conversion Tool
| Tool | Supported fit | Access and listed limits |
|---|---|---|
| Tunela | Explicitly supports singing conversion, including same-gender and cross-gender conversion. | Web only. Its free plan lists 2 conversions, 2 stem separations, 3 TTS generations, 1 video swap, and 24-hour history access. Monthly plans have capped usage; check the vendor site for current plan terms. |
| SoulX-Singer | Explicitly supports singing voice conversion, alongside singing generation and timbre cloning. | Open-source toolkit with Linux and self-hosted workflow support. Its listed synthesis languages are Mandarin, English, and Cantonese. Check the project instructions for current setup and model requirements. |
For the shortest route from a browser, use Tunela. Choose SoulX-Singer if you want to work with a self-hosted research toolkit and can follow its project setup. The available information does not establish support for a particular genre, target-voice library, upload format, or output format for either tool; check each vendor or project before planning around those specifics.
Prepare The Vocal Before Conversion
A voice converter needs the performance you want to preserve. Record or select a vocal with the intended melody, words, rhythm, and expression already in place. For example, if the goal is to change the voice on a four-line chorus, use that sung chorus as the input rather than typing lyrics and expecting a converted performance to emerge.

- Use an isolated vocal where possible. Instrumental bleed can make the source harder to distinguish from the accompaniment.
- If your starting point is a mixed song, Tunela lists stem separation, and SoulX-Singer lists vocal extraction. Those features may help prepare a vocal source; their precise controls and results are not established here.
- Keep a copy of the original recording. Compare the converted result against it for missed words, altered timing, or changes in expression.
- Use a short representative passage first, such as one verse line and one sustained note, before processing a longer song. This lets you judge whether the chosen voice suits both speech-like consonants and held vowels.
Convert The Singing Voice With Tunela
- Open Tunela’s web service and check its current conversion and account requirements.
- Prepare the vocal passage you want to convert. If the source is part of a full mix, consider its listed stem separation feature; the available details do not specify the exact upload steps or supported files.
- Choose the available conversion option and target voice that you have permission to use. Tunela lists same-gender and cross-gender singing conversion, but the available information does not establish which target voices or genre choices are offered.
- Run a short conversion. Listen for whether the words remain understandable, the notes stay aligned with the performance, and the sustained vowels sound consistent.
- If the result misses the character you want, revise the source performance or the available target-voice choice, then convert a short passage again. The specific adjustment controls are not established, so consult Tunela’s current instructions for its interface.
- When the short passage is satisfactory, process the remaining vocal and review the complete song in context. Check the current service for export details before building a downstream editing workflow around a particular file format.
Use SoulX-Singer For A Self-Hosted Workflow
- Review the SoulX-Singer project’s current setup instructions and confirm that its Linux or self-hosted workflow suits your computer and technical comfort.
- Prepare the source singing performance. The project lists vocal input, vocal extraction, and dereverberation; use those capabilities only as described in its current instructions.
- Follow the project’s documented singing voice conversion workflow to provide the source vocal and a permitted target voice or model. The available details do not establish exact commands, interface steps, or model-download requirements.
- Convert a brief phrase first and listen for preserved melody, lyric intelligibility, timing, and vocal expression. Compare the output with the original before processing a longer section.
- Check the project’s documented export workflow and inspect the result in your music setup. Its listing includes MIDI support and stem export, but does not establish a specific converted-audio export format here.
Check Consent And Terms Before Sharing
Use your own voice or get clear permission from the singer before converting or sharing a performance that uses their voice. Read Tunela’s current terms for voice use, uploaded audio, and commercial use; those licensing details are not established here. SoulX-Singer is listed as allowing commercial use, but check the project’s terms and the conditions attached to any voice or model you use.

- Words: Listen to consonants and word endings, where a change in voice character can reduce clarity.
