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

What You’ll Need

Before diving in, make sure you have the necessary hardware and software:

Hardware Requirements

Minimum: 8GB RAM, 4-core CPU, 10GB storage
Recommended: 16GB RAM, 6-core CPU, NVIDIA GPU with 8GB+ VRAM, 50GB storage
Optimal: 32GB RAM, 8-core CPU, RTX 3060 or better, 100GB SSD storage
Microphone: Any decent USB microphone works – quality matters more than brand

Software Prerequisites

Python 3.8 or 3.10 (avoid Python 3.11+ – compatibility issues)
Git for downloading the RVC repository
FFmpeg for audio processing
CUDA Toolkit 11.7 or 11.8 (for NVIDIA GPU acceleration)
Visual C++ Redistributables (Windows users)

Installation Guide – Step by Step

Step 1: Install Python and Git

Download Python 3.8 or 3.10 from python.org. During installation, check “Add Python to PATH” – this is critical. Install Git from git-scm.com using default settings.

Step 2: Download RVC WebUI

Open your terminal or command prompt and run:

git clone https://github.com/RVC-Project/Retrieval-based-Voice-Conversion-WebUI.git
cd Retrieval-based-Voice-Conversion-WebUI

Step 3: Install Dependencies

Install the required Python packages (takes 10-20 minutes):

pip install -r requirements.txt

For GPU acceleration with NVIDIA cards:

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

Step 4: Download Pre-trained Models

Run the automatic model download script:

python tools/download_models.py

This downloads about 2GB of essential base models.

Step 5: Install FFmpeg

Windows: Download from ffmpeg.org, extract to C:\ffmpeg, add to system PATH
Linux: Run sudo apt-get install ffmpeg
macOS: Use Homebrew with brew install ffmpeg

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

Open the “Train” tab in RVC WebUI
Enter a model name (e.g., “trevor_phillips” or “mob_boss”)
Upload your prepared audio files
Select version v2 for better quality
Set target sample rate to 48kHz
Use “rmvpe” for pitch extraction (best accuracy)
Train for 150-300 epochs (iterations)
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:

Launch RVC WebUI and navigate to the “Real-time” tab
Select your trained character voice model from the dropdown
Choose your microphone as the input device
Select your speakers or a virtual audio cable as output
Configure FiveM to use the virtual audio cable as your microphone
Adjust buffer size (lower = less latency, higher = better quality)
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

FAQ

Q: Is RVC AI legal to use on FiveM servers?

A: Yes, using voice conversion software is generally legal. However, check your server’s rules – some communities prohibit voice changers. Also respect copyright when cloning celebrity or character voices.

Q: Can I use this on a Mac or Linux?

A: Yes, RVC works on Windows, macOS, and Linux. Mac users without NVIDIA GPUs will use CPU mode, which is slower but functional.

Q: How much does RVC AI cost?

A: RVC is completely free and open-source. No subscriptions, no hidden fees. You only pay for electricity to run your computer.

Q: Will other players hear my converted voice?

A: Yes, when configured correctly with virtual audio cables, other players hear your converted voice through FiveM’s voice chat.

Q: Can I convert pre-recorded audio instead of real-time?

A: Absolutely. RVC excels at converting pre-recorded files, which you can then use for videos, compilations, or pre-scripted scenes.

Q: Does this work with other games besides FiveM?

A: Yes! RVC works with any game or application that uses voice chat – Discord, VRChat, Red Dead Redemption RP, you name it.

Advanced Tips

Once you’re comfortable with the basics, try these advanced techniques:

Combine multiple voice models for unique blended voices
Use post-processing (EQ, compression, reverb) for extra polish
Train models from multiple sources for more versatile character voices
Experiment with transpose settings for age variations
Create voice presets for quick character switching

Ethical Reminder: Voice cloning technology is powerful. Always get permission before cloning someone’s voice, clearly label AI-generated content, and never use voice conversion for impersonation, fraud, or harassment. Use this technology responsibly to enhance roleplay experiences, not to deceive or harm others.
