DESCRIPTION:Room acoustics such as reverberation is known to affect our ab
 ility to understand speech\, i.e. speech intelligibility\, especially when
  the environment is noisy due to auditory masking. When the listener is a 
 non-native speaker of the language spoken\, the degradation of speech inte
 lligibility is often very severe\, causing an equity issue under the curre
 nt multilingual society. Previous studies have found that speech intelligi
 bility can be improved when the target speaker and noise sources are locat
 ed in different directions from the listener by mitigating the effect of a
 uditory masking\, also known as spatial release from masking (SRM). Howeve
 r\, most studies investigated the effect on native listeners in controlled
  anechoic environments\, little is known how the acoustics of the environm
 ent would affect the SRM particularly for non-native listeners. This talk 
 introduces our recent studies that investigated how different room acousti
 cs would affect the speech intelligibility under noise between native and 
 non-native listeners of English language. Subjective listening tests were 
 conducted in rooms with different acoustical characteristics that were vir
 tually reproduced in an anechoic chamber using a sound reproduction system
 . Groups of native and non-native English listeners were recruited who tra
 nscribed sentences in noise. The results show that SRM is observed both fr
 om native and non-native listeners\, however its benefit is affected by re
 verberation as well as the listeners’ nativity of the language spoken. T
 he talk will also discuss how widely available sound reproduction systems 
 could be used for speech perception studies.
