Voice Processing Skill

This skill provides comprehensive voice processing capabilities for ElevenLabs including voice cloning (instant and professional), voice library management, audio format conversion, and voice settings configuration.

Voice Cloning Overview

ElevenLabs offers two voice cloning approaches:

Instant Voice Cloning (IVC)

Voice Cloning Best Practices

Audio Quality Requirements

1. Sample Rate: 22,050 Hz or higher recommended
2. Format: MP3, WAV, FLAC, or OGG
3. Quality: Clear audio with minimal background noise
4. Duration:
   • Instant: 1-5 minutes minimum
   • Professional: 30+ minutes recommended
5. Content: Natural speech, avoid music/effects

Multiple Files

• More files improve clone quality
• Each file should be 30 seconds to 5 minutes
• Vary intonation and emotion across files
• Consistent recording environment

Voice Settings Parameters

Stability (0.0-1.0)

• Lower values: More expressive, variable
• Higher values: More consistent, stable
• Default: 0.75
• Use case: Narration (high), Dialogue (medium), Emotional (low)

Similarity Boost (0.0-1.0)

• Lower values: More creative, varied
• Higher values: Closer to original voice
• Default: 0.75
• Use case: Clone fidelity vs. versatility trade-off

Style (0.0-1.0)

• Lower values: More neutral
• Higher values: More expressive
• Default: 0.0
• Use case: Character voices (high), Neutral narration (low)

• POST /v1/voices/{voice_id}/edit - Update voice
• DELETE /v1/voices/{voice_id} - Delete voice
• GET /v1/voices/{voice_id}/settings - Get voice settings
• POST /v1/voices/{voice_id}/settings/edit - Update settings

Troubleshooting

Common Issues

Voice clone quality is poor

• Increase audio sample duration
• Ensure clear, noise-free recordings
• Use multiple audio files
• Consider upgrading to professional cloning

API authentication fails

• Verify ELEVEN_API_KEY is set correctly
• Check API key has necessary permissions
• Ensure account has Creator plan or higher

Audio processing errors

• Verify audio file format is supported
• Check file is not corrupted
• Ensure ffmpeg is installed for conversions
• Validate sample rate and bitrate

Voice not appearing in library

• Only Professional Voice Clones can be shared
• Verify voice verification (captcha) is complete
• Check voice meets library quality standards
• Allow time for processing and review

Dependencies

Required

• curl - API requests
• jq - JSON parsing
• python3 - Audio processing scripts
• ElevenLabs API key (Creator plan or higher)

Optional

• ffmpeg - Advanced audio processing
• pydub - Python audio manipulation
• librosa - Audio analysis
