Strong vs weak forms: I can explain

We were seeing in class strong and weak forms.

The strong form of can is/kæn/ but we usually use the weak form  /Kən/

In the video below we hear people saying "I can explain" using mostly the weak form.

The strong form is only used when we stress can because we want to empasise the positive  /kæn/

The negative is always stressed but has a different sound the long vowel ɑː can't /kɑːnt/ 

Exercise:
