The method
A clinically grounded technique, in your pocket.
Speech Synk pairs Delayed Auditory Feedback — studied for decades as a fluency aid — with gentle, AI-generated coaching designed for daily practice.
How it works
A practice loop that actually clicks.
No anxious setup. No mountains of theory. Just a clean three-step ritual that fits in five minutes a day.
Pop in your AirPods
Speech Synk only runs when headphones are connected — to keep the audio loop clean and your practice private.
Tap Start. Speak naturally.
A small, customizable delay (10–200ms) plays your voice back into your ears. For many people who stutter, this simple shift unlocks fluency immediately.
Get a personal coach summary
After each session, a private AI summary highlights what worked, where you flowed, and a tiny next step for next time.
Why Speech Synk
Coaching that meets you where you are.
