The main objective of this research was to test an authentic-speech technique for improving the sound-recognition skills of EFL (English as a foreign language) students at Roi-Et Rajabhat University. The secondary objective was to determine the correlation, if any, between students' self-evaluation of sound-recognition progress and the actual (quantified) results of their progress in the course of the research period. Sixty-four participants took part in this study. The duration of the research period was two semesters. Two research instruments were utilized: 30 versions of a test-worksheet containing authentic English text for aural-test purposes, and one questionnaire which was administered at the end of each semester. The collected data were statistically analyzed by using average, percentage, frequency and standard deviation. Graphics facilitate explanation of analyses, including depiction of linear regression (trend) when appropriate. Conclusions would suggest that use of the authentic-speech technique, together with additional though minimal class exercises, resulted in a robust improvement in sound-recognition skills by all research participants. Analysis of the questionnaire results, moreover, confirmed that the students participating in this study were largely convinced they had made progress toward resolving earlier sound-recognition problem-areas.
