A teenager from India has invented a portable device that
allows a computer to construct compete sentences from the breaths of
The 16 year old has developed a generic, fast, lightweight
and portable device that can be produced cheaply in large quantity. The device, named 'Talk' records the user's exhales and
transforms these to form full sentences.
It has only two major parts: a wearable sensor placed near
the nose or mouth and a processing unit and speaker about the size of an
Arsh Shah Dilbagi, the young inventor, says that the device
will monitor and convert two different type of exhales. These exhales will be
differentiated by their different intensities and duration of time. The
intensity and duration of the breaths will be fed to the processor, which will
determine the specific breath pattern and essentially compute them into a
binary coded language - short exhales are 'dots' and long exhales are labeled
The device has shown some very promising results and has a
99% accuracy average. Arsh and his research and development team are now
working to expand the Talk's multi-language capabilities. It's to be sold for
less than US$100.
Talk isn't the first augmentative and alternative
communication (AAC) device on the market. Steven Hawking uses a similar yet
different AAC device that reads and computes eye movement. Most of the current
AAC devices are very large, bulky and expensive.
