Why do I hear a “t” sound between Quand -and- il

Question

Question: Why do I hear a “t” sound between Quand -and- il in the first sentence, in this exercise, I hear “t-il”. It seems with the “d” at the end of Quand, I am expecting a “d-il” sound. - thank you, EV

Liz, 
What you are hearing is a liaison. 
Quand is never pronounced with a terminal ‘ d ‘ sound. The terminal ‘ d ‘ is either silent, or pronounced with a ‘ t ‘ sound in a liaison. In fact, a terminal ‘ d ‘ is rarely pronounced in French, with very few exceptions.
