This study aimed at investigating the effectiveness of utilizing the linguistic mimicry technique via Neuron Linguistic Programming to improve preparatory stage students' pronunciation.The researcher adopted Quasi-experimental design. The participants of the study were (60) students enrolled in the first year preparatory stage. They were selected randomly and were classified into two groups: control group and experimental group. Three instruments were designed and applied in this study by the researcher. A questionnaire to determine the most appropriate pronunciation skills for the participants. A pre-post pronunciation test to measure the students' pronunciation skills. A rubric was designed to score the students' performance in the pronunciation test. The data were analyzed statistically by using SPSS to measure the difference between the performance of the participants in the pre and post application of the pronunciation test and to measure the differences in their performance in segmental aspects of pronunciation (vowels and consonants) and the suprasegmental aspects of pronunciation (stress and intonation). Results of the study indicated that there were significant differences in participants' performance before and after applying the linguistic mimicry technique via Neuron Linguistic Programming in favor of the post-performance. The study recommended utilizing the linguistic mimicry technique via Neuron Linguistic Programming to develop their students' pronunciation.
