Jellow Communicator is a friendly Augmentative and Alternative Communication (AAC) system that uses icons/images to enable speech. This freely downloadable app can be used for communication by those learning to speak or those having difficulty with speech. Jellow can also be used by toddlers and early learners to learn words and categories frequently used in their daily lives. Jellow’s colorful and friendly icons can help children develop an association between pictures and their corresponding word labels.

Jellow has a simple, visually appealing and easy-to-learn interface consisting central 'category' buttons and 'expressive' side buttons. The content of the app is organized into basic category buttons that make it easy for the user to access and find desired icons. The user can make the app speak out sentences by simply clicking on any of the category buttons followed by any of the expressive buttons.

Jellow has around 1000 icons and over 10,000 lines of pre-programmed text. In addition, using the 'keyboard' feature, the user can also generate new sentences and use the app to speak them out aloud. The app allows the user to choose from multiple accents American, British, Australia and South Africa.

Jellow is developed at the IDC School of Design at the Indian Institute of Technology Bombay (IIT-B) located in Mumbai. The application is still under development. If you have any suggestions for improvement, please submit your feedback/comments via email at

Can’t Register

Downloaded app and can’t get through the registration page. Seems to be some issue with the orientation/set-up. In one area I choose “USA”, then something pops up asking for “country code”, but there is no where to put a code of any kind. I deleted the app, but would like to try to download again when the kinks are worked out. App sounds promising.

Developer Response ,

Dear Chewit,

You can tap the red button with a "+" mark on it. It is located to the left of the mobile number section. This will open up a dialog with a list of countries then choose your country to get the country code. Fill the rest of the details and tap on "Register" button.

We hope the above information will help you. If you still having difficulty kindly email us on "", we will definitely help you. If your difficulty is resolved, kindly consider to review your rating.

Thank you.
