The four fundamental properties of spoken language are the phonological system, phonotactic rules, tone melodies, and the stress system. The significance of these fundamental properties is that they are used in aural decoding, which can be difficult for the L2 student. Semantic knowledge, or the knowledge of the different meanings of words, can be acquired through the use of these properties so that the student can keep up with the pace of the spoken language. Stress is the most important property in spoken language, and the most challenging for L2 students. A significant amount of attention needs to be devoted to this part of speech, also maintaining a natural speed with extra pauses in order to see a rise in comprehension.
