Speak smoothly — now, and every day after.
Ossiato plays your voice back in your headphones with a short delay (DAF) and, if you like, a slightly lower pitch (FAF). Many people who stutter find that speech flows more easily this way. An 8-week programme and a phone-call trainer help the skill carry over into everyday speech.
Playing your delayed voice through the speaker would echo and squeal. Ossiato only plays feedback into headphones — wired, USB or Bluetooth.
Wired headphones (for example EarPods) add the least delay. AirPods and other Bluetooth headphones work too; Ossiato measures their delay and shows the delay you actually hear.
No. iOS does not allow apps to process real phone calls. That is why Ossiato includes a call trainer where you rehearse calls with a simulated caller.
No. Audio is processed on your iPhone. Practice recordings and speech metrics stay on the device. See the Privacy Policy.
Subscriptions are managed by Apple: Settings → your name → Subscriptions → Ossiato Pro. Restore Purchases is in the app's Settings and on the paywall.
No. Ossiato is a practice tool, not a medical device, and it does not replace working with a speech-language professional.
