Grammar for listenersA2B1B2
Instructions. Practice hearing the difference between can and can't. The sound /t/ is often missing from negative auxiliaries, such as don't and won't. As a result, it might be very difficult to hear the difference between can and can't. As you do this quiz, you will notice that can is often not stressed and sounds like 'kn', while can't is stressed and sounds like 'can'.
