VoiceChanger.Live is the home of Echo, a free real-time voice changer built for gamers, streamers and creators. The desktop app installs on Windows or Mac and automatically creates a virtual microphone, so once you pick a voice model you simply select Echo as your input device inside Discord, Fortnite, Valorant, VRChat, OBS, Zoom, Twitch or any other app that uses a mic. Because it behaves like a normal audio input, no per-app plugin or integration is needed.
At the heart of the app is AI voice conversion built on RVC (Retrieval-based Voice Conversion). You can import ready-made community voice models spanning anime characters, horror figures, gaming radio chatter and parody voices, or clone a voice from a short audio sample to make your own. On top of conversion, the app offers stackable voice effects and filters, pitch and tone design, and a soundboard with hotkey triggers so you can fire meme sounds or custom clips through your microphone mid-conversation. Audio is processed locally, which keeps latency low and avoids shipping your live audio to remote servers.
A separate set of browser tools rounds out the toolkit: a vocal remover, stem splitter, pitch detector, audio converter, voice recorder and text-to-speech, all free and designed to keep files on your machine. Echo also ships iOS and Android apps alongside the desktop version. Core voice changing and the soundboard are free forever with no credit card, while certain models, expansions or premium tools may be sold as upgrades; the app is published by Escalera Labs S.L.
