VoicyTikTok Gift Sounds
Let your viewers pick what your game sounds like. Map TikTok gifts to in-game events — a rose triggers your next kill sound, a lion plays on your next goal. Auto-generated overlay shows viewers exactly which gift controls which moment.
Discord Voice Chat Goes Off
A bot drops into your voice channel and blasts millions of Voicy sounds the instant something happens in-game. Your whole squad hears it — nobody needs to install a thing.
Hands-Free for Live Gameplay
Once you map your sounds, you never touch the app again. Commentator listens for game events and drops the perfect reaction on its own — so your hype lands without breaking your flow or your face-cam.
Invisible & Safe
Runs quietly through Overwolf with zero impact on your frames. Fully TOS compliant — no screen reading, no game file access, just event hooks. Safe for ranked, safe for tournaments, safe for streaming.

Got questions? Here's the quick rundown.
Yes — Streaming Mode plays sounds locally so any capture software (OBS, Streamlabs, TikTok Live Studio, YouTube Studio, Twitch Studio) picks them up automatically. No special integration, no plugins. If you can hear it, your stream can hear it.
Coming in v0.5.0 — TikTok Gift Sounds let your viewers control your in-game audio with the gifts they send. Map a rose to your kill sound, a lion to your goal sound, and the next time the event happens, that gift's sound plays. Commentator auto-generates the on-stream overlay so viewers see exactly which gifts trigger which moments.
Nope. Streamers get the most out of it, but if you just play games with friends on Discord, Discord Mode drops sound effects right into your voice channel — no stream needed.
Completely free while we're in early access. Download it, use everything, no credit card, no trial limits.
Windows, through the Overwolf platform. If you don't have Overwolf, the installer takes care of it for you. Works alongside any streaming software — OBS, Streamlabs, Twitch Studio, TikTok Live Studio.
Commentator doesn't read your screen or touch game files. It listens to Overwolf event hooks, which means practically zero CPU or GPU overhead — safe for streaming at high resolutions and frame rates.
The Sound Hub is a built-in browser with millions of community sounds powered by Voicy. Search by name or category, preview before you pick, and assign sounds to any game event in seconds — no need to hunt for your own audio files. Live in v0.4.0.
Yes — upload any audio clip (8 seconds max) to your personal library, then assign it to whatever in-game event you want. Goals, kills, wins, you name it. You can also mix your own uploads with Voicy sounds on the same event.
Rocket League, Fortnite, Rematch, ARC Raiders, and League of Legends. We add new games based on what the community asks for — drop a request in our Discord.
Yes. Both modes run at the same time, and you can set up different sounds for each one — perfect for streamers who also play with a squad on Discord.
You sign in with Discord, pick your server and channel, and Commentator sends a bot into your voice chat. When something happens in-game, the bot plays the sound — everyone in the call hears it.
