Voice Cloning: Turn a Short Recording Into a Reusable Voice
Voice cloning takes a sample of someone speaking and builds a synthetic voice that can read any text you type. Musely needs 10 seconds to 5 minutes of clean audio and your confirmation that you have permission to use it. The result is a named voice in your library that speaks 39 languages and works across every Musely text-to-speech tool.

Voice cloning is the process of building a synthetic speaking voice from a recording of a real one. Musely Voice Cloning does this from a single short sample rather than hours of studio audio: upload 10 seconds to 5 minutes of speech, confirm consent, and the voice is ready in about 30 seconds. It differs from ordinary text-to-speech, where you pick from a fixed library of stock voices — here the voice is one you supplied.

How voice cloning works here
Supply a sample you have the right to use
The single most important input. 10 seconds to 5 minutes of one person speaking, in MP3, M4A or WAV, up to 20MB. Clean audio matters more than length — room echo, background music and overlapping speakers all degrade the clone.
Confirm consent
You confirm you have the speaker's permission before anything is created. If the voice is not yours, get that permission in writing; the legal exposure for cloning someone without it is real and varies by jurisdiction.
Name the voice
Give it a label you will recognise later — "narration, warm" beats "voice 3". Names matching high-risk public figures are refused.
Generate as often as you like
The voice is saved. Type any script, pick any of 39 languages, and generate. You pay for the voice once, not per sentence.
What people clone voices for
Narrate a book in your own voice
I recorded one clean minute and let the clone read the chapters I did not have the stamina to voice.
Update course audio without re-recording
When a module changes I retype the paragraph instead of rebooking a recording slot.
Keep one voice across every channel
Our ads, our explainers and our IVR all use the same voice now, which we could never afford before.
Preserve a voice that matters
With her permission I cloned my mother's voice so my kids will hear her read to them later.
Speak with a voice that sounds like you
Standard synthetic voices never sounded like me. This one does, and it reads what I type.
Carry a presenter into other languages
The presenter records once in English and the same voice delivers the Spanish and German cuts.

Voice cloning questions
Voice cloning builds a synthetic speaking voice from a recording of a real one, so the synthetic voice can read text it never actually said. Modern systems including Musely do this from a short sample — 10 seconds is enough — instead of the hours of studio audio older systems required.
Between 10 seconds and 5 minutes. Quality matters far more than length: one speaker, minimal background noise, no music underneath. A clean 30-second sample usually produces a better clone than a noisy five-minute one.
Cloning your own voice is straightforward. Cloning someone else's requires their permission, and doing it without consent can breach publicity rights, biometric-data law and fraud statutes depending on where you are. Musely asks you to confirm consent before creating a voice. If the voice is not yours, get permission in writing.
Yes — one cloned voice can read text in any of 39 languages. The accent from the original sample carries across, so an English sample reading Spanish sounds like an English speaker reading Spanish. For native-sounding regional delivery, a stock voice in that language is often the better choice.
Creating a voice costs 100 credits, charged once. Cloning is included on the Creator plan ($19.9/mo, up to 5 active voices) and Business ($99.9/mo, up to 20). Free and Professional plans include text-to-speech with the stock voice library but not cloning.
It does not sing. It does not change accent between languages. Wide emotional range — shouting, sobbing, heavy character acting — still reads as synthetic. It is strongest on narration, explainer and conversational delivery, which is what most people need it for.
