I Cannot Speak

Read full description

Two taps to be understood. I Cannot Speak is for people who cannot rely on speech. Type or tap what you need to say, then hold your phone up so the person in front of you can read it — or let your phone say it out loud. No setup. No sign-up. No learning a system of symbols. SHOW IT, LARGE Write a sentence and put the keyboard away. The words grow to fill the screen, big enough to read across a counter, a hospital bed, or a noisy room. Turn the phone around and you have been understood. OR SPEAK IT One tap reads your sentence aloud in a natural voice. Choose the voice you want and how fast it speaks. It works with the ring switch off, so you are heard even on silent. READY FOR WHERE YOU ARE Six situations — restaurant, medical, travel, transport, shopping and emergency — each holding the phrases that place actually needs. Tap the situation, tap the phrase. Edit any of them, or build situations of your own for the places you go. THE THINGS A GESTURE CANNOT SAY A row of everyday icons along the bottom of the home screen: water, a restroom, a charger, a pharmacy, a taxi. One tap shows the icon large with the sentence underneath, ready to speak. MY CARD Your name, conditions, allergies, medications and emergency contacts on one card you can hold up without typing anything. Useful in a waiting room, at a pharmacy counter, or any moment when explaining is the hard part. ACROSS LANGUAGES Show the same sentence in another language, large and clear. Useful abroad, and useful at home when the person in front of you speaks a different one. HELP FINDING THE WORDS Rough notes become a complete sentence. Type "water please" and get "Could I have some water, please?" On iPhone 15 Pro and newer this runs on the device itself. Everywhere else it uses a private connection — and if there is no connection at all, I Cannot Speak falls back to built-in phrases so you are never left with nothing. PLAN A DAY Describe what your day looks like and I Cannot Speak suggests the phrases it will need, ready before you are standing there. BUILT TO BE TRUSTED Your saved phrases, your name and photo, and everything on My Card stay on your phone. What you send to be reworded or translated is not kept — not by us, and not by the company whose model does the work. No ads, no analytics, no tracking, nothing sold. WHO IT IS FOR People living with ALS, aphasia, a stroke, Parkinson's, autism, selective mutism, a laryngectomy, or a throat injury. People recovering from surgery. Anyone whose voice has gone quiet, for a week or for good. SUBSCRIPTION I Cannot Speak is $4.99 a month or $29.99 a year, and starts with a free trial. Every feature is included in both plans — there is no cut-down version. Cancel any time in Settings.

About

Fin AAC

Fin AAC puts frontier AI to work on one thing: helping your loved one be heard. Fin is a talking picture board for people of any age who can't rely on speech. Tap a picture and Fin says the word out loud, so the people nearby hear it right away. But unlike a fixed grid that someone has to program by hand, Fin's board thinks. AI picks the words, draws the pictures and learns from every tap. WHO IT'S FOR Children and adults who are minimally speaking or non-speaking: autism, apraxia, Down syndrome, cerebral palsy, stroke, ALS, or anyone just starting out with AAC (augmentative and alternative communication). And the families, caregivers, teachers and therapists who support them. There are no boards to build: enter your loved one's age and interests and Fin is ready to use. HOW IT WORKS • It reads the moment. Fin weighs where you are (with your permission), the time of day, what they just tapped and their favorite things, and puts the words they're most likely to need right on the screen: nuggets and ketchup at a restaurant, swings and slides at the park, bath and pajamas at bedtime. • It learns them. Words they reach for in a place move to the front there. The more they use Fin, the better it knows them. • Any word, with a picture. Tap the microphone and say any word. Fin finds its picture, and if there isn't one yet, it draws one, along with related words to go with it. • "Try again" for new ideas. If none of the words fit, one tap brings a fresh set. MADE TO BE YOURS • Core words like "more", "help" and "all done" are always one tap away. • Add your own words and use family photos as pictures. • Pin favorites where they're easy to reach. • A caregiver lock keeps editing and settings from being changed by accident. • Room for more words on a tablet. FREE, PRIVATE AND CALM • Free to use, with no locked features. • No accounts, no ads, no tracking. Taps, the profile you enter and your photos stay on the device, your voice is never sent to us, and word suggestions are worked out on the device itself. Location is used only to recognise the kind of place you're in, and only when you allow it. • A quiet ocean palette, clear labels, and motion that respects your device's reduced-motion setting. MADE BY A FAMILY Fin started as a tool for our own son. We use it every day, at home, at the store and out with friends, and we fix what we find. Questions, or wondering whether Fin is a good fit for your family? Write to support@divergentsolutionscollective.com. Fin AAC is a communication aid. It is not a medical device and does not diagnose or treat any condition.
