VoiceGuard is a Minecraft server plugin that moderates voice chat by automatically detecting banned words. It integrates directly with the Simple Voice Chat plugin and uses offline AI speech recognition (Vosk) to transcribe and monitor player audio in real-time.
- Real-time Voice Moderation: Automatically detects restricted words spoken in-game.
- Offline AI Processing: Powered by Vosk, meaning all voice processing happens locally on your server without sending private audio to third-party APIs.
- Evidence Recording: Saves a
.wavaudio snippet of the violation for staff review. - Discord Integration: Optionally sends violation alerts and audio evidence directly to a Discord Webhook.
- Smart Audio Processing: Includes Voice Activity Detection (VAD) and automatic gain control to optimize AI transcription accuracy and save CPU.
- Server software: PaperMC (1.21+)
- Dependency: Simple Voice Chat plugin must be installed on the server.
I wouldn't use it in production yet, as features can still break, in that case please open an issue!
