AI Voice Changer vs Clownfish Voice Changer

AI Voice Changer is an open-source project for real-time voice conversion in streaming, gaming, content creation, and online communications. It supports Windows, macOS, and Linux, with a local web dashboard at localhost:8000 for switching models, adjusting audio settings, monitoring gain, and managing presets. Its conversion pipeline uses SoftVC, ContentVec, or HuBERT feature extraction with retrieval-based RVC models and pitch-guided conversion. Audio tools include noise suppression, voice activity detection, pitch correction, formant shifting, equalization, compression, and reverb. Virtual audio routing can connect output to OBS Studio, Discord, Zoom, Twitch, and other calling or streaming platforms. A FastAPI backend provides REST controls and real-time streaming over WebSockets. Custom voice training covers dataset preparation, pitch extraction, model training, and feature indexing; the training guide calls for at least 10 minutes of clean continuous speech. The README gives a 35–48 ms end-to-end delay target for specified hardware and supports CPU fallback, which can reach about 200 ms. It recommends a compatible NVIDIA GPU. The project describes imperceptible audio watermarks and instructs users to obtain documented consent before voice cloning, disclose AI voice synthesis, and avoid deceptive impersonation, fraud, and harassment.

Clownfish Voice Changer is free system-level software that changes audio from a microphone or another capture device for compatible applications. Listed effects include Alien, Atari, Clone, Mutation, male and female pitch, Helium, Baby, Radio, Robot, and Custom pitch. It provides a virtual microphone, character voices, a music player with playlist controls, a sound player with built-in sounds, and VST plugin support. Voice Assistant converts text to speech and lets users select a voice. Since version 1.90, VCClient can provide real-time AI voice conversion as an external effect. Compatibility examples include Steam, Skype, Hangouts, Viber, Jitsi, TeamSpeak, Mumble, and Discord. The download page lists version 2.05 for 32-bit and 64-bit Windows 10/11, plus Chrome/Chromebook and Terminal Edition options. Installation uses the default capture device and requires administrative rights.
