As a young boy, Professor Graeme Clark's school teacher asked "What do you want to do when you grow up?" 

He replied "I want to fix ears."

Professor Clark, now 85 years-old, reflects on achieving his childhood dream to give sound and speech recognition to hundreds of thousands of people across the globe.
