Speech recognition interference by the temporal and spectral properties of a single competing talker.
This study investigated how speech recognition during speech on speech masking may be impaired due to the interaction between amplitude modulations of the target and competing talker. Young normal hearing adults were tested in a competing talker paradigm where the target and/or competing talker was processed to primarily preserve amplitude modulation cues. Effects of talker sex and linguistic interference were also examined. Results suggest that performance patterns for natural speech on speech conditions are largely consistent with the same masking patterns observed for signals primarily limited to temporal amplitude modulations. However, results also suggest a role for spectral cues in talker segregation and linguistic competition.
