This is one of the biggest challenges, and always motivated by explanations that even if they are the best, if we do not listen to the sounds, it is impossible for us to understand it. Now that you hear the sounds "æ", "ə", "ɛ", "ɪ". The idea is simple.
“Can” has different pronunciations:
1. /kən/, /kɪn/, o [kn̩]—short unstressed weak form Used normally in affirmative sentences when followed by a main verb. Stress the main verb and make can as short as possible. In the case of [kn̩] do not worry about the vocal sound, just after the "/k/" say "/n/".
2. /ˈkænt/ o [ˈkɛn]—stressed negative strong form Used in negative sentences. It is always stressed and often cut off sharply by a glottal stop (short silence) at the end.
3. /ˈkænn/ o [ˈkæən]—long stressed affirmative strong form Used before a pause or when emphasized for a special reason. It is very long and stressed.
