AI Voice Cloning Software Built Around a Voice Library
Cloning one voice is a demo. Running a studio, an agency or a localisation team means managing many voices, remembering which client consented to what, and picking the right one months later. Musely treats the library as the product: named voices, up to 20 active on Business, reusable from every text-to-speech tool on the account.
Add a voice sample
MP3, M4A or WAV · 10 seconds to 5 minutes · up to 20MB
Upload audio
MP3, M4A or WAV · 10 seconds to 5 minutes · up to 20MB
Best results: one person speaking clearly and naturally — no background music or noise.

Musely AI Voice Cloning Software is a hosted tool for building and managing a set of cloned voices rather than a single one. Each voice is created from a 10-second to 5-minute consented sample, given a name you choose, and stored in a library that every Musely text-to-speech tool can draw from. The Creator plan holds 5 active voices and Business holds 20.

Running a voice library
Collect consent before you collect audio
Get written permission from each speaker, covering synthetic reproduction specifically. Musely asks you to confirm consent per voice; keeping your own signed record is what protects you later.
Clone each voice once
One consented sample per speaker, 10 seconds to 5 minutes, MP3, M4A or WAV up to 20MB. Costs 200 credits per voice, charged at creation, not per generation.
Name for the person who inherits the account
The library is only useful if names still make sense in six months. "Client A, warm read" beats "final v2". Names matching high-risk public figures are refused.
Generate from any tool
Any voice in the library can be selected from every Musely text-to-speech tool, in any of 39 languages, without re-uploading the sample.
Teams that run more than one voice
A voice per client
Five clients, five named voices, one account. I stopped keeping a spreadsheet of which file was whose.
Character voices for a series
Recurring characters need to sound the same across episodes recorded months apart.
One presenter, many markets
The same presenter voice ships in every language instead of a different stranger per region.
Instructor voices across a catalogue
Each instructor has a voice in the library, so updates match the original lesson.
Executive updates without diary time
Leadership records once, then monthly updates go out in their voice without booking them again.
Consistent voice in a product
Our in-app guidance had five different narrators. Now it has one, and new strings match.

From teams running several voices
What matters once you pass the second or third voice.
“Twenty active voices on one plan is what made it viable. Per-voice pricing elsewhere would have cost us several times more.”
“Naming is underrated. Being able to label voices properly means anyone on the team can pick the right one without asking me.”
“The consent confirmation is a good prompt but it is not a contract. We still keep our own signed releases, which the docs are upfront about.”
Running cloning software at team scale
Up to 5 active cloned voices on the Creator plan and up to 20 on Business. Voices stay in the library until you delete them, and deleting one frees a slot.
Each cloned voice costs 200 credits once, at creation. Generating with a voice you already have does not spend that fee again — generation draws from your monthly media credit allowance (1,000 on Creator, 10,000 on Business).
Voices live on the account, so anything cloned there can be selected from any Musely text-to-speech tool on that account. Treat account access as the control — anyone who can sign in can use the voices in the library.
Musely records that you confirmed consent, against a consent version, at the moment each voice was created. That is an internal record of your confirmation, not a signed release from the speaker. For commercial work, keep your own written permission from each person whose voice you clone.
A consent confirmation at upload and a name-based deny-list that refuses clones named after high-risk public figures. The deny-list only reads the name typed in, so it will not catch a public figure's voice uploaded under an ordinary name. It is a deterrent rather than voiceprint verification, and account-level process still matters.
Between 10 seconds and 5 minutes of clean speech as MP3, M4A or WAV, up to 20MB. A quiet room, one speaker, natural pace, around 30 to 60 seconds is the sweet spot. Ask for it in the same message as the written permission so you get both together.
