Voidol
Real-time AI voice changer for VTubers with licensed character voices
About Voidol
Voidol is a real-time AI voice changer from Japan's Crimson Technology, built for VTubers and creators. The current Voidol3R combines an AI mode for character voice conversion, a SYNTH mode for low-latency pitch and formant shaping, and an RVC mode for higher-quality AI conversion on NVIDIA GPUs. Its character voice models are produced with official permission.
