title: "Voice Cloning"
description: "Clone any voice from just a few seconds of audio"
---
## Overview
Voicebox uses **Qwen3-TTS** from Alibaba to achieve near-perfect voice cloning from just a few seconds of audio. The model captures prosody, emotion, and natural cadence.
## How It Works
<Steps>
<Step title="Upload or Record Sample">
Provide 10-30 seconds of clear speech from the target voice
</Step>
<Step title="Model Analysis">
Qwen3-TTS analyzes vocal characteristics, tone, and speaking patterns
</Step>
<Step title="Voice Profile Created">
The model generates a voice embedding for synthesis
</Step>
<Step title="Generate Speech">
Use the profile to generate any text in the cloned voice
</Step>
</Steps>
## Best Practices
### Sample Quality
<CardGroup cols={2}>
<Card title="Do" icon="check">
- Use 10-30 seconds of audio
- Clear, consistent speaking
- Minimal background noise
- Natural speaking pace
</Card>
<Card title="Don't" icon="xmark">
- Very short clips (< 5 seconds)
- Heavy background noise
- Music or overlapping voices
- Heavily processed audio
</Card>
</CardGroup>
### Multiple Samples
Adding multiple samples from the same speaker can improve quality:
- Different speaking styles (casual, formal)
- Different emotions (happy, serious)
- Different recording conditions
<Tip>
The model will learn a more robust representation from diverse samples.
</Tip>
## Supported Languages
Currently supported:
- English
- Chinese (Mandarin)
More languages coming soon.
## Limitations
<Warning>
Voice cloning should only be used with consent. Ensure you have permission to clone someone's voice.
</Warning>
- Quality depends on sample clarity
- Works best with consistent speaking tone
- May struggle with extreme accents or speech impediments
- Background noise reduces quality
