administer the same tests to students at different proficiency levels with different back ground in large area in order to draw more accurate conclusion. It is recommended that future researchers administer this technique with practicing of differing rates that is, fast, moderate, slow, so they would realize speech sound in different version of speech. This study at last administered seven session during the term on 80 students. The increase of two session in every week with larger number of students is recommended .in order to economize on time it would be much better if differing rate are pre- recording, prepare and played.
