Elevenlabs Voice Cloning

Language Considerations:

• Record in target output language
• Cross-language may have accent
• Example: English sample → Spanish output = English accent

Audio Characteristics

What AI Learns:

• Emotional range in samples
• Prosody variations
• Speaking pace patterns
• Voice timbre and characteristics
• Inflection patterns

Important: AI can only replicate what it's trained on. Flat, monotonous samples = flat, monotonous voice.

Cloning Workflow

// 1. Prepare samples (3+ files recommended)
const samples = [
  'sample1_conversational.mp3',
  'sample2_professional.mp3',
  'sample3_emotional.mp3'
]

// 2. Clone voice
await mcp__elevenlabs__voice_clone({
  name: "Professional Narrator",
  files: samples,
  description: "Warm, authoritative voice for educational content"
})

// 3. Test and refine
// Generate test samples
// Evaluate quality
// Re-record if needed

Quality Optimization

Pre-Recording Checklist

• Silent room test (record 10s silence, check for noise)
• Microphone positioned correctly
• Pop filter in place
• Recording levels set (-12dB to -6dB peaks)
• Script prepared with varied content
• Warm up voice (read aloud 5 minutes)

Post-Recording

• Listen to each sample
• Remove takes with mistakes
• Normalize volume if needed
• Export as high-quality MP3 or WAV
• Verify no clipping or distortion

Common Issues & Solutions

Issue: Clone sounds robotic

• Add more expressive samples
• Include varied emotional range
• Record longer samples (3+ hours)

Issue: Inconsistent voice

• Ensure consistent microphone technique
• Record all samples in one session
• Same environment/equipment

Issue: Background noise

• Re-record in quieter location
• Use noise reduction (carefully)
• Better microphone/acoustic treatment
