The biggest challenge faced by deaf, blind, or
dumb people is communication. Some people face
difficulties in communicating with others due to their
inability of hearing or sighting. Some of them are deaf or
blind by born whereas a few of them lose their hearing
or visual ability by accidents. Recently, there have been
studies and researches on how to make their life easier
by different approaches such as mobile applications,
devices based on hand gloves for the deaf-dumb, the
internet, etc. This project aims to develop a method for
communication for people with sensory impairment with
the help of IoT. The main purpose of the project is to
help them communicate more easily with both the
ordinary people as well as sensory impaired. The
proposed system would make better use of technologybased on Raspberry Pi with some advanced features of
converting. In this project, there are two major
conversion units. One of them is converting audio into
text, which favors the deaf people. The other one is an
image to audio conversion, where the image is converted
into text via image processing and the text is converted
into audio, this proportion of the system is useful for the
blind people. There are few additional features for blind
people such as a voice calculator, voice assistant, and
object detector to help them with moving around and
their basic needs. The output for deaf people will be
shown on the LCD and the blind people will be able to
hear through the speakers. It is expected that
communicating for sensory impaired will be easier by
using the system. The prototype can be accessed easily
by the deaf and for the blind people. There is a voice
assistant by which they can access all the functions
mentioned above. It can be used to help the sensory
impaired in their education. An observation of the
outcomes of the project was done by providing different
types of components for a better result. All the
components worked properly to make the system more
efficient. The main goal of the project is to reduce
difficulties in their communication, among themselves
and with ordinary people and this project can be made
more useful in the future by making the design simpler.
