How to make AI sing a melody you wrote

By the builder of Mozarella, a software engineer and musician. Updated July 27, 2026.

You wrote a melody. You have lyrics. You want to hear them sung, and you cannot sing. Half the tools that promise this will throw your melody away and generate their own. This is the map of the ones that actually sing what you wrote.


Two different products are sold as AI singing

Melody generators take your lyrics and invent everything else. Suno, Udio, and a long tail of lyrics-to-song sites work this way. Fast, sometimes impressive, but the tune is theirs. If you came in with a melody, it does not survive the trip.

Melody followers take notes plus words and perform exactly that line. The field is called singing voice synthesis. This is the session singer you can afford: your pitches, your rhythm, your words, a voice you chose.

The test is simple: if there is nowhere to enter notes, it is not going to sing your melody.

Mozarella (ours)

Mozarella is our tool, so read this entry knowing that. It is a song sketch pad in the browser: you set key and chords, write the melody in the app or let it propose one you then edit, type lyrics, pick one of four voices, and get a sung take of exactly that line inside the arrangement. Nothing to install, and the melody never leaves your hands.

It is the only tool here where writing the song and hearing it sung happen in the same place. The honest limits: it is a sketch pad, not a vocal-editing suite. You will not do surgical vibrato work here, and the deep vocal features sit in premium. Composing is free to try.

Synthesizer V Studio

The quality ceiling of the field. Desktop software: you draw or import the melody, type lyrics on the notes, and shape pitch curves, tension, and breath until it stops sounding synthesized at all. Producers use it on finished records. The Studio 2 Pro editor is $99 one time with a voice included, and each additional voice is $79, so the cost grows singer by singer. Expect a real learning curve to match the ceiling.

ACE Studio

The most complete dedicated vocal studio: a desktop app for Windows and Mac with some companion tools on the web, over a hundred voices, and voice cloning. Subscription pricing at roughly $21 a month regular price, with rendering metered by monthly credits. If your melody already exists as MIDI and you want deep control over the performance, this is the serious dedicated option. You bring the composition; it only handles the singing.

Vocaloid 6

The tool that invented the category, and still the center of a huge voicebank culture. Desktop, one-time license: starter packs with the editor and a voice run about $198. The sound is more stylized than Synthesizer V, which is either its charm or its problem, depending on whether you want a Vocaloid record or a human-sounding demo.

Emvoice One

A plugin that lives inside your DAW. Type lyrics onto MIDI notes in Logic, Ableton, or Reaper, and it renders a realistic vocal in place. Voices are licensed one at a time, and current prices only appear once you install the plugin and log in. The right answer when the song already lives in a DAW session and you want the vocal to appear on a track, not in another app.

The different job: voice conversion

Tools like Kits AI and the RVC family do not read notes at all. You sing the line, badly if necessary, and they replace your timbre with another voice while keeping your pitch and timing. If you can carry a tune but hate your tone, this path is cheap and fast. If you cannot sing it at all, you are back to the tools above.

Generators answer "write me a song." These tools answer "sing the one I wrote." Know which question you are asking.

Common questions

Can Suno or Udio sing my exact melody?

Not reliably. They generate a song influenced by your input, and the melody that comes back is theirs, not yours. If the notes matter, you need singing voice synthesis: a tool that takes notes plus lyrics and performs exactly that line.

What if my melody is just a hum or a voice memo?

Convert it to notes first. Audio-to-MIDI tools can transcribe a clean hum, or you can retype it into a piano roll by ear. Once it exists as notes, any tool on this page can sing it. The other route is voice conversion: sing the line yourself, keep your timing, and have AI replace the timbre.

Do I still own the song if an AI sings it?

The melody and lyrics you wrote remain your work. An AI performing them does not change who wrote them, the same way a session singer would not. Prompt-generated songs are the murky case, not this one.

Is there a free way to try this?

Mozarella is free to compose in, with vocal takes as part of premium. Synthesizer V offers 14-day trials of the editor and each voice. Both let you hear the idea before committing.

On ownership, the longer answer is in Who owns a song made with AI? For how this differs from prompt generation, see Mozarella vs Suno.
