The English language has a "phonetic system" to help foreigners learn how to pronunciate words.
But i must warn you, native spearkers DO NOT learn this, we don't need to. So never ask a native speaker for help with your phonetics.
How do we learn how to pronunciate new words then? I hear you ask...simple -
active = ak-tiv
terminate = tur-muh-neyt
etc.
Check out www.dictionary.com when you check a word, it will give you the pronunciation next to it.
