Why Speech Synk
Coaching that meets you where you are.
Built around the science of fluency, and the lived experience of people who stutter.
Real-time DAF
Hear your own voice with a tunable 10–200ms delay. For many people who stutter, that single acoustic shift unlocks fluency immediately.
A coach in your pocket
After every session, you get a short, plain-English summary of what flowed and one small thing to try next time.
Tunable to you
Find the delay that fits how you talk. Save presets for the situations that matter: a tough call, a stand-up, an intro.
Progress that matters
See trends over weeks, not seconds. Notice where you sound like yourself, and lean in.
Daily practice prompts
Five-minute prompts for the moments that actually trip people up: phone calls, intros, ordering coffee, the start of a presentation.
Private by design
Audio is encrypted on your device. Names and identifiers are stripped before anything reaches our AI. No ads. No data sales.
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 needs headphones to run safely. No acoustic feedback, and no one else hears a thing.
