Experience true Delayed Auditory Feedback. MuteMe uses a precise 170ms delay and pitch-shifting to challenge your focus. Onetime purchase, no subscriptions.
MuteMe is an advanced Speech Jammer designed to test your focus, concentration, and speech fluency.
By utilizing zero-latency Delayed Auditory Feedback (DAF) and pitch-shifting technology, MuteMe feeds your own voice back to your ears with a precise 170ms delay. This creates a fascinating cognitive challenge, making it incredibly difficult to read or speak normally without stuttering or stopping completely.
Whether you are testing your own concentration or challenging friends, MuteMe delivers a seamless, high-quality audio experience in a beautifully minimalist interface.
KEY FEATURES
• Authentic DAF Engine: Precision 170ms delay combined with pitch-shifting for maximum cognitive disruption.
• Reading Challenges: Includes built-in, scrollable cards with tongue twisters and complex texts in 10 different languages to test your fluency.
• Privacy First: 100% on-device processing. No data is collected, and your voice never leaves your phone.
• Premium Experience: A single, one-time purchase. No subscriptions, no ads, and no hidden fees.
IMPORTANT HARDWARE REQUIREMENT
• Wired Headphones Strictly Required: You must use wired headphones or earbuds. Wireless and Bluetooth devices introduce inherent hardware latency that permanently breaks the precise audio timing required for the jammer to function correctly.
Plug in, tap JAM, and try to speak.
