Speech Jammer°

Speech Jammer° records your voice and plays it back after an adjustable delay, implementing Delayed Auditory Feedback (DAF) to make speaking challenging. It includes tongue twisters, the ability to record sessions, and share recordings with friends.

Use with noise-canceling headphones for best results. The app features a simple, easy-to-use layout and lets you casually experiment with speaking under lag in a fun, controlled way.
