While learning listening comprehension, learners might encounter several difficulties, Underwood (1989) notes: learners might be unable to control the speed of the speaker; they can’t ask for words to be repeated all the time; their limited knowledge of vocabulary makes listening comprehension difficult; they show some difficulties in recognizing discourse markers; they express difficulties in concentrating in a foreign language; they suffer from a desire to understand the meaning of every word; and they lack contextual knowledge.
