This is the second in a three-part series reporting from Toronto’s booming Artificial Intelligence sector where new technologies are being pioneered that will permanently change all of our lives

Just 45 seconds in the company of scientist Frank Rudzicz and his machines is all it takes to determine whether or not you are suffering from Alzheimer’s disease.

In that time, the complex Artificial Intelligence (AI) algorithms that the 37-year-old and his team have developed are able to pick apart your voice and predict the severity of the disease to an accuracy of around 82 per cent (and rising).
