The influence of female versus male speakers' voice on speech recognition thresholds in noise: Effects of low- and high-frequency hearing impairment
Speech, Language and Hearing(2014)
摘要
Purpose To investigate the effect of female versus male speakers' voice on the ability to recognize speech in noise in two groups of sensorineural hearing-impaired listeners, one group with impairment at low frequencies and the other at high frequencies. Method Eight participants with high-frequency hearing impairments (Hf-HI) and seven with low-frequency hearing impairments (Lf-HI) participated. Sixteen normal hearing (NH) participants served as reference. The sentences from the hearing in noise test, read by a female or a male speaker, were presented monaurally with a background noise. In an adaptive procedure, the mean speech recognition threshold, for 50% correctly recognized sentences, was calculated for the female and male voice and each test subject. Results The Hf-HI group had significantly greater difference in signal-to-noise ratio (SNR) results between female and male voices. Irrespective of hearing impairment, the female voice required 2.1 dB better SNR. In addition, the NH group showed a smal...
