An AI singing voice generator that sounds like you.

An AI singing voice generator produces a sung vocal from lyrics and a melody. Octa already does that for every song with its stock voices. The singing voice cloning layer goes one step further: it learns the timbre of a specific person — you — and performs generated songs with that voice, on pitch and in time.

Two systems work together. The generation engine, Octa-Initium, writes and arranges the song and produces the performance. OctaTune, our in-house pitch-correction model family, keeps the cloned vocal in tune with the arrangement without flattening it into a robot. Both are ours, trained on licensed data, and documented with their limits.

The goal is not “a voice”. It is your voice, on a song that did not exist a minute ago.

• Record over a guided beatThe app plays a beat and scrolls lyrics; you sing along for about a minute. No studio, no microphone beyond the phone’s.
• A private profile is builtYour voice model belongs to your account. Nobody else can select it, and you can delete it any time.
• Generate a song as usualType a sentence or paste lyrics, pick your voice as the singer, press Generate.
• OctaTune keeps it in tuneThe clone’s pitch is corrected against the arrangement gently — the model learned where rule-based tuning over-corrects and smooths those moments.

Recording languages: English, French, Japanese, Hindi and Indonesian. You can keep several voices and switch between them.

Cloned vocals drift. Classic pitch correction snaps every note to a grid, which is why cheap tools sound like a robot. OctaTune v10 was trained to predict the correction a grid would apply and then evaluated on its own: it corrects less than the grid on average and smooths the mechanical jumps at note boundaries, while a separate rule leaves fragile frames untouched. The result is a vocal that is in tune but still breathes.

We tested a heavier alternative — a neural pitch tracker plus a vocoder resynthesis path — and rejected it: the tuning was identical, but the resynthesis shifted the timbre by several decibels and dulled the highs. Keeping your timbre intact mattered more than the extra model.

You may clone your own voice. The recording flow is designed around that: you sing live, in the app, over our beat. Octa does not accept uploaded recordings of other people, does not imitate named singers, and blocks artist names in prompts. Your voice profile is private to your account and deleted when you delete it.

• A noisy one-minute recording gives a rougher clone; a quiet room and a steady phone distance make the biggest difference.
• Extreme ranges — a whisper-low verse or a screamed chorus — are performed, but the clone is most convincing near the range you recorded in.
• Voice profiles are periodically refreshed; when the app asks you to re-record, it takes about a minute and restores full quality.
• Voice cloning lives in the Android app today; the browser studio generates with stock voices and shares the same library.

• a warm acoustic ballad about coming home, fingerpicked guitar — sung by my voice
• upbeat pop about a summer that ends too soon, bright synths, my voice on the chorus
• a slow French chanson about Paris in the rain, piano and strings, my voice

Generate the song first with a stock voice if you want to hear the arrangement before you spend a take on it; you can regenerate with your voice afterwards.
