The impact of compression rate and sex on the results of time compressed speech test

Abstract

Background and Aim: Time compressed speech test is one of the most common types of monaural central auditory processing tests assesses the temporal resolution. The aim of the present study was to evaluate the impact of compression rate and sex on results of this test among the young individuals with normal hearing.
Methods: The Persian version of time compressed speech test with six lists of 25 monosyllabic words was prepared in three compression rates of 0, 40 and 60 percent. 36 young people with normal hearing and age range of 18 to 30 years were assessed with time compressed speech test in the most comfortable level in each ear separately. Then scores were compared between two ears, genders and three compression rates.
Results: There was a significant difference between word recognition scores of three compression rates (p<0.0001). Significant difference was revealed between word recognition scores of both ears, just in the 60% compression rates. No significant difference was found between the word recognition scores of the two genders.
Conclusion: Word recognition scores decreases with increase of the presentation rate of speech stimuli. Time compressed speech test accompany with other audiologic tests can be used to examin the auditory temporal processing and speed of speech processing as a test battery.
