Streaming voice changer
Turn a stream into a character show. Voices AI Live converts your mic with AI and OBS captures it as a normal audio input - for Twitch, YouTube, Kick, TikTok LIVE, or local recordings.
Works with OBS Studio and Streamlabs Desktop on Windows 10+ and Apple Silicon Macs with macOS 14+. Not affiliated with the OBS Project, Streamlabs, Twitch, or YouTube.
Tap a voice to preview it - open one for setup details.
Download the free app for Windows or Mac and accept the virtual microphone install. Restart if your computer asks you to.
Preview the voices in the app - or clone your own from a 5-second recording - and select one.
Click + under Sources, add Audio Input Capture, and set Device to CABLE Output (VB-Audio Virtual Cable) on Windows or Voices AI Virtual Mic on Mac.
Mute or disable your original mic in the Audio Mixer so viewers only hear the AI voice, then go live.
Add the Voices AI microphone as its own Audio Input Capture source instead of changing your global Mic/Aux device. The AI voice then gets its own fader and filters, and you can switch per scene - character voice in the gameplay scene, your real voice on Just Chatting.
In Settings > Audio, set Mic/Auxiliary Audio to Disabled (or mute it) so your real voice does not play underneath the AI voice.
Voices AI Live already outputs a clean voice, so skip heavy noise suppression on the new source - a light compressor and a limiter are usually enough. If your voice and your facecam drift apart, add a small Sync Offset to the source in Advanced Audio Properties.
Streamlabs Desktop works the same way: add an audio input source and pick the Voices AI device. Because OBS and Streamlabs stream whatever they capture, the voice change works on every platform you stream to.
VTubers can pair an AI voice with their model for a full character, and Discord can use the same virtual mic at the same time so your co-op partners hear the voice too.
Start Voices AI Live first, then fully quit and reopen OBS so it rescans audio devices. Look for CABLE Output (VB-Audio Virtual Cable) on Windows or Voices AI Virtual Mic on Mac. If it is still missing, restart your computer to finish the virtual microphone install.
Your original mic is still active. Mute it in the Audio Mixer or set Mic/Auxiliary Audio to Disabled in Settings > Audio.
Open Advanced Audio Properties and add a Sync Offset to the Voices AI source until your lips match.
Turn off extra noise suppression in the app you are talking in, close GPU-heavy programs you are not using, and check your computer meets the Voices AI Live system requirements.
