The Problem

This experiment was designed to test the effect of misarticulation on listener comprehension. Of the many authorities who suggest that poor speaking reduces comprehension, Knower, Phillips, and Koeppel state: "Poor speaking seems to be the least effective method of presenting informative materials. There is a direct relationship between the quality of speaking performance and the amount of material recall." One of the important factors which contributes to effective speaking is correct articulation. According to Van Riper and Irwin: "If you misarticulate your speech sounds, it interferes with communication, and your speech is judged as abnormal." Articulation defects are the major abnormality of speech.
