'Speech is a right and not a privilege'

19 Dec 2017

Dr Vishal Rao has created a simple device to help throat cancer patients in India to speak again. Replacement prosthetic voice boxes can cost up to $1,000 (£750) but his Aum box costs just $1.

In India, around 30,000 patients a year are diagnosed with cancer of the larynx. Many face having the voice boxes removed and they can no longer speak.

Replacement prosthetic voice boxes can cost up to $1000 - which is unaffordable. But one doctor has invented a cheap solution to give these patients their voices back.
