Abstract: Objective To evaluate the test -retest reliability of sentence materials, and to standardize Man_darin Speech Test Materials (MSTMs). Methods Forty normal-hearing subjects aged from 18 to 30 years old were recruited in this study. The sentence materials were tested at 9 dB HL to these subjects according to the prepare ex_periment. The retest was carried out in the same condition after an interval of 14~28 days. The difference between test and retest score was examined by t-test, and the critical difference (CD) was analyzed with 95% confidence in_terval (CI). ResuIts There was no significant difference between the test and retest scores about speech perception performance. The critical difference was 18. 93% at 95% confidence interval, and the number of the corresponding key words was 10. ConcIusion The results showed that sentence materials of MSTMs have good test-retest relia_bility except list 6. The interventions could be considered effective just when the difference of the same subject's score exceed 18. 93%, that means 10 key words are necessary to improve that the intervention is effective.
