About this app

Jellow Plus Communicator is a friendly Augmentative and Alternative Communication (AAC) system that uses icons/images to enable aid communication in adults learning to speak or with difficulty with speech and language. Jellow Plus helps non-verbal adults to communicate by constructing their own phrases/sentences and gradually learn to speak - especially those with Autism, Cerebral Palsy, Down’s syndrome.

Jellow Plus is also an extension of Jellow Basic. It has all the icons and much more in this version. The expressive buttons which were part of the Emotional Language Protocol (ELP) driving Jellow Basic is available in Jellow Plus. These features make it easy for children using Jellow Basic to graduate to Jellow Plus as they grow up, making it possible to communicate better.

Jellow Plus is designed especially for adults, can be used to form words, phrases and sentences frequently used in their daily lives. Jellow’s library of icons can help adults communicate using pictures along with their corresponding word labels.

Jellow Plus has a library of around 5000(?) icons designed specially with feedback from users. These are organized in different categories based on parts of the speech to make it convenient to form a sentence. Some of these categories are verbs, adverbs, adjectives, nouns, expressions, etc.

In addition, using the 'keyboard' feature, the user can also generate new sentences and use the app to speak them out aloud. The current version of the app allows the user to choose English language with multiple accents Indian, American, British, Australia, Nigeria along with a choice of voices. Other languages are being introduced.

Jellow Plus is developed with support from IDC School of Design at IIT Bombay, UNICEF, Ministry and Hospitals. It is designed iteratively with regular feedback from users namely children, parents, therapists, teachers and care givers.
