It is very important to understand what speech anxiety is and to overcome it in a speaking education. However, current speaking education only shows the cause of speech anxiety and how to get over it at a low level. That is because there has been no specific theory to analyze and discuss the speaking process with regard to anxiety. This study is for framing a draft of the education related to speech anxiety, which establishes a theoretical model to give a perceptible indication of speech anxiety. This study suggests the analysis model of speech anxiety by means of ECG (electrocardiogram) to examine speech anxiety. There have been few people who has tried to measure speech anxiety because it is associated with medical examination. This research puts emphasis on setting up a simple and comprehensible model to analyze. Speech anxiety is explained by three steps, considering that the ECG result will be adapted to the education related to speech anxiety in the future. The first step is to understand that there is a link between speech anxiety and the autonomic nervous system. The second step is to comprehend the process of analyzing speech anxiety on the basis of ECG. The third step is to understand the education model which is comprehended through the representative types. This study has significance because it suggests a theoretical model that serves as an index in which the response in the autonomic nervous system is analyzed and a comprehensible strategy for analyzing speech anxiety is built.
