The need for alternative and augmentative communication (AAC) in all children is not the same[2] but AAC can aid in expressive language and also support intelligible speakers in developing and using communication skills in varied situations. While the range and flexibility of AAC has grown over the years, making devices accessible to children at varied economic and regional backgrounds, is still a challenge.  \nKAVI-PTS is designed as a picture-to-speech Android application, and has been made available in several Asian languages. This application is conceived of as an inexpensive software alternative to communication charts. It can be easily configured to adjust contrast levels and customize selection modes, enabling children to have access to a tailor-made communication solution.  \nIndex Terms: picture to speech application, AAC, Assistive technology  \n1. Introduction  \nWith the advent of mobiles and Tablets, the use of alternative and augmentative communication (AAC) software in a public setting such as a classroom, or a playground has become very easy.The primary mode of communication for children with motor disabilities that also affects there speech, e.g. cerebral palsy (CP), are often picture charts and flash cards. These aids are difficult to prepare and customize for individual use, they can become expensive to purchase and they often are worn out by use. A simple app to replace the use of picture charts and flash cards was required. KAVI-PTS goes beyond this, as it helps to build conversations, communicate independently, and allows individuals to express their feelings and emotions.  \nMost individuals want the communication to be in their local language. The Indic language support in KAVI-PTS makes the software accessible to people more comfortable in vernacular languages.  \nIn addition, both the images and the audio can be categorized and added through the app, making it is highly customizable for the specific needs of the individual. The added functionality of KAVI games makes the software more interactive allowing for an improvement in vocabulary through these picture games  \n2. Functionality Description  \nKAVI-PTS began as a picture to speech software, developed for the Andorid platform in collaboration with Mindtree  \nFoundation, Bengaluru. Today, it has grown to include a number of features, multiple languages, and even acts as a platform for artists to present their picture library. However, the core of the software lies in its Indic text to speech engine, that has been developed by a consortium of academic researchers.  \nThe system architecture is as shown in Figure 1:  \n| SQLite LIBRARIES |\n| --- |\n| LINUX KERNEL |\n\nFigure 1 : System Architecture of KAVI-PTS  \nKAVI-PTS is launched in GridView. Upon launch of the application, it displays the various categorized item names. Each item represents a category like People, Feelings, Things, Body Parts, Food, Places etc.  \nA sample screen shot displaying various categories that appears as the application is launched is shown in Figure 2.  \nFigure 2: Home Screen displaying Categories  \nUpon selection of any of these main items the sub list of the main item appears, and the images pertaining to those sub items appear on the screen.  \nOn pressing or selecting any of the items, an audible voice is played with zooming the item and then, a new screen is  \nlaunched.
