"The principles of aural-oral approach underline this text... The term aural-oral is used because it describes the point of entrance into the study of the total structure of a given language... Priority is given to the establishment of habits of hearing and understanding the basic multilevel patterns of the flow of sounds, and to the acquisition of skill in producing those sounds accurately before one turns to the task of learning the conventional written representations and to an appreciation of their esthetic use" (author).
