The objectives of this study are to confirm that figurative expressions are important in speech and suggest various stages of activities that can help students refine such expressions in their speech manuscripts using cognitive metaphor theory. The speech manuscripts of students and evaluation results of their speeches are closely related. However, students cannot easily reflect on the characteristics of their speeches in all the processes involved in speech preparation, including writing its manuscripts. Therefore, to improve their abilities of making a good speech in a speech class, the students must be provided detailed guidelines for each step of the activity of writing a speech manuscript. This study discusses expanding the range and level of students` activities in speech generation in order to develop guidelines for them to create newer and more diverse expressions.
