# Voice Cloning

Create custom AI voices trained on your own audio samples for a branded, personalized voice agent experience.

---

Create a custom AI voice that sounds like you (or anyone you have permission to clone). Voice cloning uses ElevenLabs Instant Voice Cloning to synthesize voices from short audio samples -- no training phase, ready in seconds.

> **Warning:** Voice cloning requires a Studio plan or higher.

## How It Works

1. Record or upload a short audio sample (1-2 minutes)
2. ElevenLabs analyzes vocal characteristics (pitch, timbre, prosody, accent)
3. A custom voice is generated instantly
4. Select it as your voice agent's voice

Cloned voices are shared across all apps in your organization.

## Creating a Custom Voice


  **1.** 
    <strong>Open Voice Settings</strong>

    Go to your app's **Build** page and open the **Voice** card. Voice mode must be enabled.
  


  **2.** 
    <strong>Add Custom Voice</strong>

    Find the **Custom Voices** section and click **Add Custom Voice**.
  


  **3.** 
    <strong>Record or Upload Audio</strong>

    Choose one method:

    **Browser recording** (recommended):
    - Click Record and speak naturally for 1-2 minutes
    - Re-record if needed

    **File upload**:
    - Upload a pre-recorded audio file
    - Supported formats: WAV, MP3, M4A, OGG, WebM, FLAC
    - Maximum file size: 50MB
  


  **4.** 
    <strong>Name and Create</strong>

    Give your voice a memorable name (e.g., "CEO Rachel" or "Support Persona"). Click **Create Voice**. The voice is available immediately.
  


  **5.** 
    <strong>Select the Voice</strong>

    In the voice selection dropdown, your custom voices appear at the top. Select it to use with your voice agent.
  


## Recording Tips for Best Quality

The quality of your clone depends entirely on the quality of your audio sample.

### Duration

- **Optimal:** 1-2 minutes
- **Too short** (&lt;30 seconds): May lack vocal variety
- **Too long** (&gt;5 minutes): Can introduce instability
- The AI captures voice characteristics best from concise, focused samples

### Environment

- Record in a quiet room with soft furnishings (curtains, carpets reduce echo)
- Turn off fans, air conditioning, and notifications
- Close windows to block outside noise
- The AI replicates **everything** it hears -- background noise becomes part of the voice

### Microphone Technique

- Position the microphone about 20cm away (two fists distance)
- Speak slightly off-axis to reduce plosive sounds (hard P's and B's)
- Use a pop filter if available
- Avoid breathing directly into the mic

### Audio Quality

- Peak levels: -6dB to -3dB (loud parts don't clip)
- Avoid clipping/distortion at all costs -- the AI can't recover from it
- Standard sample rate (44.1kHz or 48kHz) works well

### Delivery

- Maintain consistent tone and energy throughout
- Don't switch between animated and subdued delivery
- Read with natural pacing -- not robotic, not theatrical
- Use your own writing or scripts for natural rhythm

## Managing Custom Voices

- **Delete a voice:** Remove it from your organization's voice library at any time. This also removes it from ElevenLabs.
- **Multiple voices:** Create as many custom voices as your plan allows
- **Cross-app usage:** All apps in your organization can use any custom voice
- **Audio privacy:** Your recording is stored encrypted and never shared publicly

## Troubleshooting

**Voice doesn't sound right?**
- Re-record with better audio quality (less background noise, no clipping)
- Try a longer sample (aim for 1-2 minutes of natural speech)
- Ensure consistent tone throughout the recording

**Voice not appearing in selection?**
- Check that the creation completed successfully
- Refresh the voice settings page
- Verify you're on a Studio plan or higher

**Upload failing?**
- Check file size (max 50MB)
- Verify the file format (WAV, MP3, M4A, OGG, WebM, FLAC)
- Try a different format or re-export the audio
