The speech jammer app that actually works with AirPods. Hear your own voice played back with a slight delay and try to keep talking — it's nearly impossible. Speech Jammer uses delayed auditory feedback (DAF) to disrupt your speech in real-time, creating hilarious results at parties, on camera, or just for fun. ā–ø HOW IT WORKS Plug in any headphones, tap Start, and speak. Your voice comes back delayed through your headphones, making it incredibly hard to talk normally. • Adjustable delay — slide from 100ms to 500ms to find your breaking point • Works with AirPods — Bluetooth and wired headphones both supported • Real-time waveform — watch your voice visualized as you speak • Headphone detection — automatically warns if headphones aren't connected ā–ø 4 JAMMER MODES Go beyond basic delay with unique audio effects that make speech even harder. • Classic Delay — the original DAF effect at your chosen delay • Pitch Shift — hear your voice delayed AND pitch-shifted for extra confusion • Echo Chamber — multiple decaying echoes of your voice overlap • Speed Ramp — delay increases over time until you can't speak at all ā–ø CHALLENGE MODE 16 built-in tongue twisters and reading challenges across 4 difficulty levels. • Easy to Impossible — from "Count to Twenty" to the Gettysburg Address • Personal best timer — track how long you can speak under each challenge • Challenge a Friend — share your time and dare friends to beat it • New challenges added in updates ā–ø RECORD & SHARE Capture your funniest jammed speech moments and share them instantly. • One-tap recording — hit record while the jammer is running • Playback with progress — listen back to your jammed audio • Share anywhere — Messages, TikTok, Instagram, AirDrop • Recording history — all sessions saved with mode and delay info ā–ø DESIGNED FOR FUN Built from scratch for iOS with attention to detail. • Clean, modern interface — no clutter, just the jammer • Haptic feedback — feel when you start and stop • Volume safety — output is capped to protect your hearing • Works fully offline — no internet required, ever ā–ø PRICING FREE: • Classic Delay mode with adjustable delay • 3 recordings per day • 3 starter challenges PREMIUM SUBSCRIPTION Speech Jammer Pro is available with the following subscription options: Premium Monthly: $2.99/month Premium Annual: $19.99/year (Save 44%) — includes 7-day free trial Unlock all 4 jammer modes, unlimited recordings, all 16 challenges, and remove all ads.
