Summary :
Objective: to determine whether speaker gender affects speech discrimination scores, in normal hearing and simulated high frequency hearing loss situations. Materials and Methods: listeners were twenty normal volunteers. The speech stimuli were eight phonetically balanced monosyllabic word lists, uttered by a male and a female speakers. These lists were low-pass filtered at 1500, 2500 and 3500 Hz’s to represent high frequency hearing loss. To obtain speech discrimination scores, the subjects listened to each of the eight lists in a different filtering and talker conditions in a randomized order. For statistical analysis, Mann-Whitney U test was used. Results: in normal hearing situation, the scores obtained by male and female speeches, were similar (p=0.60). On the contrary, statistically significant differences were observed in all of the three high frequency hearing loss situations (p<0.01). Conclusion: Female speech is significantly more difficult to discriminate than male speech in normal-hearing subjects with simulated high frequency hearing loss and probably in patients with high frequency hearing loss.
