To clone a voice for singing with AI, record a clean vocal reference, separate the instrumental if necessary, then either train a singing voice from lyrics or MIDI or convert an existing sung performance into the target voice. For a complete vocal draft, start with LyricToMelody AI. For a song cover, use VocalMe, On4t AI Voice Cover, Altered Studio or Applio, then check the result for pitch, timing, pronunciation and artifacts.
Choose The Singing Workflow
| Tool | Best Use | Access And Limits Stated In The Listing |
|---|---|---|
| LyricToMelody AI | Train a custom singing voice for a new vocal arrangement | Free plan; paid from $10/mo annually. Generates sung drafts from lyrics or MIDI, trains from uploaded or recorded vocals, and exports audio, MIDI and separate stems. |
| VocalMe | Replace the singer in an existing song | Paid with a 7-day trial. Preserves a song’s melody and rhythm, accepts an audio sample for custom voice cloning, and combines YouTube input with stem separation. |
| Altered Studio | Performance-to-performance voice morphing | Free plan allows 3 minutes of voice morphing per month; Creator and Professional prices are listed with annual billing from $30/mo. The listing does not establish singing-specific model support, so verify a sung workflow first. |
| Applio | Free local or real-time voice conversion | Free and cross-platform for Windows, macOS and Linux. Supports custom model training, model blending, batch inference, TTS, exports and CLI automation; results depend on the voice model. |
| On4t AI Voice Cover | Quick browser experiments with covers | Free browser-based conversion with downloadable audio, uploaded audio or YouTube URLs, and language, emotion and pitch controls. |
Prepare A Reference And Backing Track
- Get permission from the person whose voice you will model. Keep a record of that permission before uploading anything.
- Record or select a clear reference in the vocal style you need. Keep the singer close to the microphone and avoid background music, reverb and overlapping voices where possible.
- Prepare the performance you want to transform. If the source is a finished mix, use LALAL.AI to separate vocals and instruments. Its listing supports previews, batch processing on paid plans and uploads up to 2 GB; the free Starter plan provides previews but not full result downloads.
- Keep the original instrumental and the isolated vocal at the same start point. This makes it easier to compare timing after conversion.
Build A New Singing Draft In LyricToMelody AI
- Open the web application and upload or record the reference vocals for custom singing-voice training.
- Enter your lyrics or import MIDI. Set the melody and rhythm so the model has the intended notes and syllables.
- Describe the take in plain production language, such as: “Use a close, centered lead vocal; clear consonants; gentle vibrato only on sustained notes; keep the written melody and lyric timing.” Treat this as a direction for the draft, not a guarantee of a particular genre or vocal effect.
- Generate a short section first. Listen for vowel changes, clipped consonants, unstable pitch and breaths that land off the beat.
- Revise the MIDI, lyric syllables or vocal reference and regenerate only the weak section. Export separate stems when you are ready to edit the vocal against the instrumental in a DAW.
LyricToMelody AI lists commercial rights on paid plans. Starter projects are retained for 7 days, so export work you need to keep.

Consent, Licensing And Release Checks
Clone only your own voice or a voice supplied with explicit permission. Read the current terms for the tool, model and source recording before distributing the result. LyricToMelody AI states that commercial rights are included on paid plans; Altered Studio’s free plan states an attribution license. The supplied listings do not establish commercial terms for VocalMe, On4t AI Voice Cover or LALAL.AI, so confirm them with the vendors. For Applio, check the separate terms attached to the model, dataset, vocoder and any source content.
If you upload music to Spotify, identify authorized vocal impersonation and follow the platform’s AI disclosure requirements. Spotify announced that vocal impersonation is allowed only when the impersonated artist has authorized it and supports DDEX AI disclosures in credits (Spotify’s 2025 policy announcement). Spotify also announced an AI Persona badge for identities that may be AI-generated (Spotify’s AI Persona announcement).
