Voice Cloning

How to Clone a Voice

1. Start creating a new host (or edit an existing one).
2. Complete the Name and Backstory steps.
3. On the Voice Type step, select Voice Clone.
4. Upload or record your audio samples on the Voice Clone step.
5. Complete the remaining steps and save.

Jellypod creates your voice clone after you finish creating the host. You will see a toast notification: "Creating your voice clone! This may take a few moments..." followed by confirmation when it is ready.

Uploading Audio Samples

Drag and drop a file into the upload zone, or click Browse files. Each sample starts uploading right away, so you can keep adding samples while earlier ones are still in progress.

Accepted formats: MP3, WAV, M4A, OGG, OGA, FLAC audio, or a video file (MP4, M4V, MOV, WEBM, MKV, AVI). If you pick a video or an audio file in a format Jellypod cannot use directly, Jellypod pulls the audio track out in your browser and converts it to MP3 before uploading, so you can use a selfie clip, Zoom recording, or phone video as a sample. You will see "Extracting audio from your file…" while this happens. If the file has no audio track, or it cannot be processed, Jellypod shows an error so you can pick a different file.

Recording Audio

Click the Record Audio button to record directly in your browser. A three-second countdown appears, then a live recording state with a red pulsing dot, timer, and audio visualizer. Click Save Sample when finished.

Audio Requirements

• Minimum total audio: 30 seconds across all samples (60 seconds recommended)
• Minimum per sample: 10 seconds
• Maximum samples: 10
• Maximum file size: 10 MB for an audio file. Video files (or other files that need audio extraction) can be up to 500 MB, but the extracted audio must still be 10 MB or under.

Managing Samples

After uploading or recording, each sample appears in the Audio samples list showing:

• File name
• Duration
• A play/pause button to preview
• A download button to save the sample
• A remove button to delete the sample

While a sample is uploading, its row shows Uploading…. If an upload fails, the row shows Upload failed with a Retry button to try again. Removing a sample cancels its upload if one is still in progress. You can continue to the next step once every sample finishes uploading; retry or remove any failed sample first.

Tips for High-Quality Clones

The page displays three tip cards to guide you:

• Record somewhere quiet: Background noise and room echo get cloned right along with your voice.
• Use a good mic: A wired headset or external mic captures you far more cleanly than a laptop.
• Vary your delivery: Read from a script and shift your tone, pace, and emotion. A monotone read makes a monotone clone.

Your voice clone captures not just your voice, but also your tone, pace, emotion, and speaking style. Poor audio quality in your samples directly affects clone quality.

If Your Voice Clone Doesn't Sound Right

If your clone sounds different from your original recording, try these steps:

1. Check recording quality: Make sure your samples had clear audio with minimal background noise.
2. Re-record with better delivery: Record again with a clear, consistent tone and varied emotion. Avoid monotone delivery.
3. Try the style toggle: Some voice clones have a "More Consistent vs More Expressive" style option. Try switching between styles to find one that works better for your needs.
4. Regenerate speech blocks: If the clone works overall but specific episodes sound off, try regenerating those speech blocks to get a different rendering with the same clone.

If you consistently get poor results, you may need to start over with new, higher-quality audio samples.

Frequently Asked Questions

How much audio do I need to create a voice clone?

You need a minimum of 30 seconds of total audio across all samples (60 seconds is recommended), with each individual sample being at least 10 seconds. You can upload up to 10 samples, each up to 10 MB after processing.

Can I upload a video instead of an audio file?

Yes. Jellypod extracts the audio track from a video file (MP4, M4V, MOV, WEBM, MKV, or AVI) in your browser and converts it to MP3 automatically, so you can use a selfie clip or screen recording as a sample.

Can I clone someone else's voice?

You should only clone voices you have permission to use. Make sure you have the consent of the voice owner before creating a clone.
