This medical device helps throat cancer patients, whose voice box is removed, get their voice back. Dr Vishal Rao and his team have developed this unique device.

Most throat cancer patients who undergo laryngectomy are unable to speak after the surgery due to removal of voice box. Normally, these patients go for the western prosthesis, however, the most popular european prosthesis costs around INR 25000-30000, which many patients cannot afford. The Aum Voice Prosthesis is priced at INR 50 (popularly known as $1 device)
