GTA Voice Models (RVC AI) – Create Custom Character Voices for FiveM

Want to take your FiveM roleplay to the next level with unique character voices? RVC (Retrieval-based Voice Conversion) AI technology lets you transform your voice into different characters, celebrities, or completely original personas in real-time. Whether you’re creating a gruff mob boss, a professional news anchor, or a quirky shop owner, RVC AI gives you the tools to match your voice to your character.

This guide walks you through everything you need to know about using RVC AI for GTA V and FiveM roleplay. We’ll cover what RVC is, how it works, installation steps, and practical tips for creating convincing character voices that enhance immersion without sounding robotic or artificial.

What is RVC AI?

RVC AI (Retrieval-based Voice Conversion Artificial Intelligence) is a free, open-source voice conversion technology that transforms your voice into another person’s voice while preserving your words and emotions. Unlike text-to-speech which generates speech from text, RVC converts existing speech from one voice to another in real-time or near real-time.

The technology uses neural networks to analyze voice characteristics and apply them to your input audio. You can train custom voice models using just 10-30 minutes of clean audio samples, making it accessible for creating unique character voices for roleplay scenarios.

Why Use RVC for FiveM Roleplay?

• Character Immersion – Sound like your character actually should, not just you with a funny accent
• Voice Variety – Play multiple characters without everyone recognizing your real voice
• Professional Quality – Rivals commercial voice changers costing $15-30 monthly
• Completely Free – Open-source with no subscription fees or limitations
• Real-Time Processing – Works during live gameplay with minimal latency (50-200ms)
• Custom Training – Create unlimited unique voices tailored to your characters
• Privacy Protection – Mask your real voice if preferred
• Cross-Character Consistency – Save different voice models for different characters

Step 6: Launch RVC WebUI

Start the interface:

python infer-web.py

The web interface opens at http://localhost:7865 in your browser.

Creating Your First Character Voice

Gathering Training Audio

You need 10-30 minutes of clean audio from the voice you want to clone. For GTA character voices, you can:

• Extract audio from GTA V cutscenes or mission dialogue
• Download voice clips from GTA wiki or YouTube compilations
• Record yourself performing the character voice (if creating original characters)
• Use celebrity or public figure voices from interviews and videos

Audio Quality Tips:

• Use mono audio at 44.1kHz or 48kHz sample rate
• Remove background music using tools like Ultimate Vocal Remover
• Trim silence and normalize audio levels
• Include varied emotions and speech patterns for better results

Training Your Model

1. Open the “Train” tab in RVC WebUI
2. Enter a model name (e.g., “trevor_phillips” or “mob_boss”)
3. Upload your prepared audio files
4. Select version v2 for better quality
5. Set target sample rate to 48kHz
6. Use “rmvpe” for pitch extraction (best accuracy)
7. Train for 150-300 epochs (iterations)
8. Click “Train model” and wait 1-3 hours depending on your GPU

Using RVC During FiveM Gameplay

Once your voice model is trained, here’s how to use it during live roleplay:

1. Launch RVC WebUI and navigate to the “Real-time” tab
2. Select your trained character voice model from the dropdown
3. Choose your microphone as the input device
4. Select your speakers or a virtual audio cable as output
5. Configure FiveM to use the virtual audio cable as your microphone
6. Adjust buffer size (lower = less latency, higher = better quality)
7. Start speaking – your voice converts in real-time with 50-200ms delay

Optimizing for Best Quality

Getting natural-sounding results requires tweaking a few settings:

• Index Rate: Set to 0.5-0.65 for speaking (0.75+ for singing)
• Protect Value: Use 0.25-0.33 to preserve consonants
• Transpose: Adjust ±12 semitones for gender changes
• Filter Radius: Set to 3 for smooth output

Common Issues & Solutions

Issue: Voice sounds robotic or artificial

Solution: You need more training data (aim for 15-20 minutes) or more epochs (try 200-300). Make sure your training audio is clean without background music. Lower your index rate to 0.5 for more natural speech.

Issue: High latency during real-time conversion

Solution: Reduce buffer size in settings. Close other programs using your GPU. If using CPU-only, expect higher latency – consider upgrading to a GPU setup.

Issue: CUDA out of memory error

Solution: Lower batch size during training. Close other GPU applications. Try gradient checkpointing if available in settings.

Issue: Voice model not appearing in dropdown

Solution: Click “Refresh voice list” multiple times. If still missing, restart RVC WebUI completely. Check that the .pth file is in the /weights folder.

Best Practices for FiveM Roleplay

• Train separate models for each character you play regularly
• Keep model names organized (character_name format)
• Test voices offline before using in live scenarios
• Have backup plans if RVC crashes during important roleplay
• Respect server rules about voice changers (some prohibit them)
• Don’t use copyrighted voices commercially without permission
• Label AI-generated content when sharing clips or recordings
