On this week’s Why Factor Jo Fidgen meets an Englishwoman who suffers from a rare condition known as Foreign Accent Syndrome which causes her to speak with a French-sounding accent. What can her situation teach us about accents and why they matter? Jo explores why English sounds different across the globe and takes an accent lesson from a Canadian drama teacher. And did you know some animals have accents too?
