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 played back with a tunable 10–200ms delay. The clinically proven technique that quiets disfluency in the moment.
AI coaching
After each session, an on-device-aware AI summarizes patterns and gives you gentle, specific encouragement for next time.
Tunable to you
Adjust the delay until you find the setting that lets you flow. Save your favorite presets for different speaking contexts.
Progress that matters
Watch fluency trends over weeks, not seconds. Identify the moments where you feel most confident and lean into them.
Daily practice prompts
Realistic scenarios — phone calls, intros, ordering, presentations — designed to build muscle memory without anxiety.
Private by design
Audio is encrypted on-device. Personally identifying details are stripped before any AI processing. No ads, ever.
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.
