About Ossiato: Stutter & Stammer
Ossiato is a pocket tool that helps you speak more smoothly right now — and practise every day so you can speak confidently without it. Put on headphones and tap once. You hear your own voice with a short delay (DAF) and, if you like, a slightly lower pitch (FAF). Many people who stutter find their speech flows more easily with this kind of feedback. It keeps working with the screen locked — in conversations, presentations and interviews. ONE CALM BUTTON • Presets for conversation, presentations, calls and practice — switch in a second. • Quick adjust: delay and pitch sliders right on the main screen. • Live Activity, Control Center, Action Button and Apple Watch to start and stop without unlocking. HONEST LATENCY • Ossiato measures your headphones and shows the delay you actually hear. • Wired headphones give the shortest delay; AirPods and other Bluetooth headphones work too. A SKILL THAT STAYS • An 8-week programme, 10–15 minutes a day: reading aloud, gentle onsets, stretched speech, free speaking. • Support is reduced step by step so the skill carries over into everyday speech. PHONE-CALL TRAINER • Rehearse booking a doctor, talking to a courier or answering a recruiter. • Choose a patient, hurried or clarifying caller. Delayed feedback can fade out during the call. PROGRESS YOU CAN HEAR • Your own ratings, pace and pauses, week by week. • Listen to the same text a month ago and now. PRIVATE BY DESIGN • Audio is processed on your iPhone. Recordings never leave the device. No account, no ads, no tracking. OSSIATO PRO Free: Live DAF with no time limit, the Conversation preset, three exercises, three practice calls a week and 7 days of progress. Ossiato Pro unlocks pitch shift (FAF), masker and metronome, all presets and your own, the full 8-week programme and exercise library, unlimited practice calls, full progress with recordings, Control Center, Action Button and Apple Watch: yearly with a 7-day free trial, monthly, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in your Apple ID settings. Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://evgeniybruchkovskiy.github.io/ossiato-legal/privacy.html Ossiato is a practice tool, not a medical device, and does not replace working with a speech-language professional. iOS does not allow apps to change the sound of real phone calls — that's why Ossiato includes a call trainer.
What’s new
Version 1.0.1 · Updated October 5, 2026
Clearer store page and a few small improvements. After a session that felt smooth, Ossiato may now ask once whether you'd like to rate it — it really helps other people who stutter find the app.
