Then, the problems may appear if students cannot produce the appropriate speech sound based on its features because of the complexity of its phonological system. Since the segmental feature is related with the speech sound emitted by the speech organs, this study is set to examine only the English voiced-voiceless consonant sound as the limitation of the study. Similarly, in the suprasegmental feature, the aspect of word and sentence stresses are also set to examine.
