The effect of sentence repetition on speech intelligibility in noise

The effect of sentence repetition on speech intelligibility in noise was investigated. The benefits of repetition on word intelligibility under continuous and fluctuation noise conditions and the effects of noise conditions on the parameters of the performance-intelligibility (PI) function for sentence spoken once or twice, was examined. Eighteen French-speaking subjects aged between 20 and 30 years with normal hearing were presented lists of 20 sentences from the Canadian French HINT test under three different noise such as continuous speech spectrum noise, and modulated speech-spectrum noise. The subjects were asked twice to repeat heard word under different noise conditions and a score was marked for each response. It was observed that repetition improves the SRT from 2.0 to 5.4 dB and increases the slope of PI function. Result shows that the speech intelligibility is highly pronounced in modulated noise and least in continuous noise.
