🎭 Voice Cloning Guide

Why Voice Cloning?

Voice cloning makes BoliGen feel personal and authentic in any language. Instead of a generic AI voice, BoliGen can speak exactly like you, a trusted person, or any voice that creates comfort across cultural boundaries.

🚀 Quick Start: Clone Your Voice in 3 Minutes

Step 1: Record Your Voice

Requirements:

30 seconds to 2 minutes of clear speech
Quiet environment (minimal background noise)
Natural speaking style in your preferred language
Good quality microphone (built-in laptop mic works fine)

Tips for Best Results:

Speak naturally and conversationally
Include variation in tone and emotion
Read a paragraph in your native language
Don't pause too long between sentences
For multilingual cloning: Record samples in multiple languages for best results

Step 2: Clone on Cartesia

Visit Cartesia Voice Lab
Copy your Voice ID (format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)

Step 3: Configure BoliGen

Edit src/agent.py and update the TTS configuration:

# Find this section in the entrypoint() function:
tts=inference.TTS(
    model="cartesia/sonic-3", 
    voice="your-cloned-voice-id-here"  # Replace with YOUR voice ID
)

Step 4: Test Your Voice Across Languages

Restart BoliGen:

python src/agent.py console

Try speaking in different languages - BoliGen now speaks in YOUR voice across all 100+ supported languages! 🎉

🌐 Multilingual Voice Customization

Language-Specific Voice Profiles

Create different voices for different language groups:

# Professional voice for English/European languages
ENGLISH_VOICE = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

# Warm voice for Indian languages
INDIAN_VOICE = "yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy"

# Friendly voice for Asian languages
ASIAN_VOICE = "zzzzzzzz-zzzz-zzzz-zzzz-zzzzzzzzzzzz"

# Auto-switch based on detected language
voice_id = get_voice_for_language(detected_language)

Voice Parameters

Fine-tune voice characteristics per language:

tts=inference.TTS(
    model="cartesia/sonic-3",
    voice="your-voice-id",
    # Language-specific tuning:
    speed=1.0,        # Adjust for language rhythm
    emotion="neutral" # Cultural-appropriate emotions
)

🔒 Voice Cloning Ethics & Privacy

Important Guidelines:

✅ DO:

Clone your own voice
Clone voices with explicit written consent
Use for personal, educational, or authorized purposes
Respect voice ownership and intellectual property
Consider cultural sensitivities across languages

❌ DON'T:

Clone someone's voice without permission
Impersonate others maliciously
Use cloned voices for fraud or deception
Share voice models without authorization
Disrespect cultural or religious sensitivities

BoliGen's Position: We strongly advocate for ethical AI voice cloning across all cultures and languages. Always obtain consent before cloning someone's voice, and use the technology responsibly for beneficial purposes.
