How to Clone a Voice

Voice cloning lets you create a custom AI voice from a short audio recording. Once created, you can use it exactly like any other voice on VocalLab.

Before you start

• You need a VocalLab account (free accounts get 1 clone slot)
• You need a short audio recording of the voice you want to clone — 5 to 30 seconds
• The voice must be your own, or you must have explicit permission from the voice owner

Step 1 — Name your clone & pick a language

1. Go to Clone Voice
2. Enter a name for your clone (e.g. "My Voice", "Digital Twin")
3. Select the language the voice will speak — this affects the accent and phoneme model used

Supported languages: English, Spanish, French, German, Portuguese, Italian, Japanese, Korean, Chinese, Russian, Arabic, Hindi, Hebrew, Polish.

Note: Japanese, Russian, Hindi, and Polish are marked Experimental — quality may vary.

Step 2 — Upload your audio sample

You have two options:

Option A — Upload a file

• Drag and drop or click to browse
• Accepted formats: MP3, WAV, WebM
• Maximum file size: 4 MB
• Duration: 5–30 seconds (longer files are auto-trimmed to 30 s)

Option B — Record directly in the browser

• Click Record and allow microphone access
• Speak naturally — recording stops automatically at 30 seconds
• Click Stop when done

What makes a good sample

• One clear voice, no background music or noise
• Normal speaking pace and volume — not whispering or shouting
• A quiet room with minimal echo
• Recorded close to the microphone

Optional: Remove background noise

Enable Noise Removal to automatically clean up background noise before cloning. Recommended if your recording isn't in a quiet environment.

Consent

Check the consent box to confirm you have the right to clone this voice. This is required before proceeding.

Click Start Cloning when ready.

Step 3 — Processing

VocalLab sends your audio to the AI engine. This usually takes 30–90 seconds. Do not close the tab.

Step 4 — Done

Your clone is ready. You'll see a success screen with two options:

• Use Now — go to My Voices and start generating
• My Cloned Voices — view all your clones

Using your clone

Your clone appears in My Voices under the Cloned tab. Select it in the voice picker on any generation page and use it like any other voice.

Clone limits

Free and Lite users with 1 existing clone must delete it before creating a new one.

Troubleshooting

"You must upload at least one audio file" Add a file before clicking Start Cloning.

"Audio is too short" Your recording is under 5 seconds. Record or upload something longer.

File not accepted Only MP3, WAV, and WebM files are supported. Convert other formats (M4A, AAC, FLAC) to MP3 or WAV first.

"Your plan includes 1 voice clone. Delete your current clone to create a new one." Free and Lite plans allow 1 clone at a time. Go to My Voices, delete your existing clone, then try again.

Clone sounds robotic or wrong language Make sure you selected the correct language in Step 1. Re-create the clone with a cleaner, longer sample (15–25 seconds works best).
