KAVI – PTS, A Ray of Hope for Children with Speech Delay

Mindtree’s effort to make a difference to the society has witnessed many milestones. The latest in the list is ‘Kommunicator Audio Visual Interface’, an Augmentative Alternative Communication (AAC), is a Picture-To-Speech mobile app, designed to help children with language delay, in the age group of 1 – 3 years.

For a child, communication with others is no hindrance as they use both verbal and non – verbal means, which develops as they grow. But, in the case of a child with speech delay, communication is a task. The best alternative available for such children is communicating using visuals. Hence, the use of images in the early years of learning becomes imperative, which forms the core of the application ‘Kommunicator Audio Visual Interface’.

Kommunicator Audio Visual Interface, using Picture to Speech feature (KAVI-PTS) is an Augmentative Alternative Communication (AAC) built using Android operating system. This is at present a mobile app focusing only on the visual communication of the child using pictures; however, there are plans to enhance the features to include text to speech features very soon. This can be installed on any Android compatible tablets, or smartphones.

KAVI-PTS can also help children with Autism, Learning Disabilities, and Cerebral Palsy in its early stages.

Teaching today – an overview

Scenario 1 – Using printed charts:

  1. A teacher in the classroom teach children using printed charts, by pointing at each image and asking them to respond
  2. Teacher reads out and spells the name of the object and asks the children to follow suit.

In both the above cases, the child would respond repeating and spelling the word. But, a child with speech delay will only point out to the object.

Scenario 2 – Practice and communicate with others

Children are put to practice of identifying the objects with the help of their parents/guardians.

In this case, as the practice progresses, the child may identify the objects, its colors and shapes, the touch and feel of the object using its speech and gestures. But a child with the speech delay can get to this level with the help of AAC.

The AAC helps in enhancing the ability of the child to develop verbal language, by not only releasing the pressure to speak, but also subsides the frustration in communication through alternative channels.
