Twitch Soundboard & Voice Changer
Your AI-powered live audio wingman for Twitch streaming. React to subs, donations, raids, and chat moments with the perfect sound — suggested by AI in real-time. Community-curated sound packs, TTS voice personas for character bits, and seamless OBS integration. No complex routing. No plugins. Just better audio.
Why Twitch Streamers Love EchoDeck
Soundboard apps exist. But none of them understand your stream. EchoDeck listens to game audio and chat context to suggest reactions in real-time. Accept with one tap. Your chat sees a streamer who's always on point — because your AI wingman is doing the heavy lifting.
🎉 Sub & Dono Reactions
Instant sound reactions when someone subs, donates, or raids your channel. Set custom sounds per tier — Tier 1 gets a cheer, Tier 3 gets the victory fanfare. Gifted subs? Confetti cannon. Every supporter feels special because the audio feedback is immediate and personalized.
🎭 Voice Personas for Bits
Switch to an AI voice persona mid-stream for character bits, roleplay segments, or viewer challenges. Type what your character says, AI speaks it in any voice — deep narrator, anime girl, robot, drill sergeant. Perfect for Just Chatting segments and interactive content.
🤖 AI Context Suggestions
EchoDeck's Smart Listener analyzes your game audio and conversation flow. Clutch play? Victory sound queued. Fail moment? Sad trombone ready. Chat going wild? Hype sound suggested. You're always reacting at the perfect moment — because AI handles the timing.
⌨️ Stream Deck & Hotkeys
Bind any sound to Stream Deck buttons, keyboard shortcuts, or gamepad inputs. Global hotkeys work while you're in-game — no alt-tabbing. Organize sounds into boards for different stream segments: gaming, Just Chatting, IRL, and special events.
OBS Setup — 60 Seconds, No Plugins
EchoDeck routes audio through VB-Cable (auto-installed), which OBS picks up as a standard audio source. No browser sources, no VST plugins, no complex routing matrices. Just one audio capture and you're live.

Frequently Asked Questions
Does EchoDeck work with Streamlabs OBS?
Yes. The setup is identical — add an Audio Output Capture source in SLOBS and select "CABLE Input." EchoDeck works with OBS Studio, Streamlabs OBS, and any streaming software that supports audio capture sources.
Can my Twitch chat hear the sounds?
Yes. Because OBS captures the virtual audio cable, all sounds play through your stream audio. Your viewers and VOD recordings include every sound effect, voice persona, and AI suggestion.
Can I use EchoDeck with Discord AND Twitch at the same time?
Yes. Sounds route through the virtual microphone, which both Discord and OBS can capture simultaneously. Your co-streamers on Discord and your Twitch audience both hear the audio.
Is EchoDeck free for streamers?
The free tier includes unlimited soundboard slots, unlimited uploads, hotkey bindings, and community sound packs. AI voice personas and advanced context suggestions are available on Pro ($4.99/mo). Most streamers find the free tier more than sufficient.
