Tap images. Type words. Speak. Proloquo2Go is an easy to use communication app for people who cannot speak or need help being understood. Featuring natural sounding voices, including real children’s voices, Proloquo2Go is a simple yet powerful AAC (augmentative and alternative communication) tool. The app is fully customizable and can be utilized to build language skills and grow with a person’s communication, supporting both beginning and advanced communicators. Parents, therapists, teachers and users around the world recognize Proloquo2Go as the gold standard in AAC solutions. The app is used by people with autism, Down syndrome, cerebral palsy, Angelman syndrome, and others with speech difficulties. The app is available in English, Spanish, French, and Dutch and supports bilingual use, so you can switch languages on the fly. Proloquo2Go in action: Learn and grow Studies show that just 200-400 words make up 80% of what we say. Known as core words, they act as the basis of Proloquo2Go’s research-based Crescendo™ vocabulary. Users can grow from single words to full sentences in the same app. Crescendo puts core words in consistent locations for easy access and motor-planning. The vocabulary works with AAC best practices like modeling (where you use an AAC system to talk with the user) to develop language skills. Crescendo offers no limit on language development with a 10,000+ fringe word vocabulary and customizable vocabulary levels. Finally, with Progressive Language, words are gradually revealed step-by-step, helping users learn words and their location as their communication expands. Easy editing Customizing Proloquo2Go is a breeze! Quickly and easily add new words. Use the app’s built-in library of 25,000 symbols or use your own photos by taking pictures within the app or selecting them from your photo library. For users with fine-motor challenges and vision impairments, Proloquo2Go offers options like 23 pre-programmed grid sizes and accessibility settings which support switch scanning and Apple’s VoiceOver screen reader. Everything from appearance to access is customizable so you can make it your own. Type and speak Besides tapping images, Proloquo2Go also lets you type what you want to say. The app includes a Grid Keyboard arranged alphabetically for people learning to type. For more experienced typists, Proloquo2Go includes a Typing View with a QWERTY keyboard and word prediction that offers suggestions based on what you are typing. Hello! ¡Hola! Bonjour! Hallo! Proloquo2Go lets you select a language and region for the Crescendo vocabulary. Two languages can be used at the same time, allowing seamless bilingual speech. Over 100 included downloadable natural-sounding adult and children’s voices rounds out your choices to use the app your way. A helping hand AssistiveWare is here for you every step of the way.

SHAPE CODING® Lite is a free demonstration version of the full SHAPE CODING® app. This is designed for teachers and speech and language therapists / pathologists to use with children and young people who are having difficulties producing and understanding English sentence structure and grammar. As with the full SHAPE CODING® app, it uses the SHAPE CODING® system which has been shown in several research projects to help children and young people with language disorders increase the length and complexity of sentences they can understand and use and improve the accuracy of their sentence production. The SHAPE CODING® Lite app has less functionality and flexibility than the full SHAPE CODING® app but can be used to form simple sentences. The SHAPE CODING® system uses a visual coding system to show the rules for how words are put together in sentences, to develop the child’s understanding of spoken and written grammar and to develop their ability to use grammar successfully to express themselves. The system includes use of colours (word classes), arrows (tense and aspect) , lines (singular and plural) and shapes (syntactic structure). These are all included in the app (although not all are enabled in the Lite version), but the professional controlling the app can choose which features display for the student, so that it is personalised to their current levels and targets. Settings are preserved for the student between uses. The Lite app allows only a single teacher and student, but the full version can have multiple teachers and students. The SHAPE CODING® Lite app is equipped with a basic set of words which can be inserted into those shapes which are enabled to make simple sentences. A much wider range of shape options are enabled in the full version than the Lite version, so more grammatical rules can be taught and more complex sentences created. The app uses text-to-speech, so that students who struggle to read can also use the app. This app assumes a certain degree of familiarity with the SHAPE CODING system. For more information see www.shapecoding.com. Training on how to use the SHAPE CODING(R) system is available from https://training.moorhouseinstitute.co.uk/. For a demonstration of the features of the full version of the app (some of which are also enabled in the Lite version), see: https://shapecoding.com/demo-videos/, and for Frequently Asked Questions see: https://shapecoding.com/app-info/faqs/ Follow us on Twitter @ShapeCoding, Facebook @ShapeCoding and Instagram @shape_coding or if you have any problems or feedback, please contact us at training@moorhouseschool.co.uk Please review our privacy policy https://shapecoding.com/privacy-policy-apple/
