epSpeak โ Give Them a Voice epSpeak is a picture-based communication app (AAC) that helps children and adults who are nonverbal or have limited speech say what they mean โ one tap at a time. Tap a picture, hear the word. It's that simple to start, and it grows with the user from single words all the way to full sentences. WHY FAMILIES CHOOSE epSpeak - Big, friendly buttons โ designed for small hands and first-time users. - Meet Echo, a warm animated character who speaks each word with you, so communication feels personal, not clinical. - Two ways to talk: a simple Sound Board for tapping single words, and a full AAC word board for building sentences from core vocabulary. - A research-informed, color-coded word board (Modified Fitzgerald layout) keeps core words always within reach. - Works in your language โ available in English, Spanish, French, German, Portuguese, Italian, Chinese, and Arabic. BUILT FOR THE WHOLE TEAM epSpeak connects the people who support a communicator: - For caregivers: Organize categories, add your own photos and words, and personalize the experience from your phone or the web portal. Adjust voice speed, button size, and what's shown โ and changes appear on the user's device within seconds. - For practitioners (SLPs, teachers, therapists): Work across multiple clients, set communication goals, track progress, and leave notes โ all in one place. PERSONAL AND PRIVATE - Add your own photos so the words match the user's real world โ their cup, their dog, their favorite snack. - Hide or show individual items per user, so what's on screen fits the moment. - Your data is encrypted on the device, and end users never see notifications or pop-ups that could overwhelm them. DESIGNED TO REDUCE FRUSTRATION, BUILD CONNECTION Every feature is shaped around real communication: clear audio, an optional auto-return so the screen steps back when a word is done, and a calm, uncluttered interface that keeps the focus on the message โ not the menus. Whether you're a parent starting your child's communication journey, a teacher supporting building skills session by session, epSpeak gives every voice a way to be heard. Start the conversation today.
