Consonant identification in noise by native and non-native listeners: Effects of local context


Abstract  Speech recognition in noise is harder in second L2 than first languages L1. This could be because noise disrupts speech processing more in L2 than L1, or because L1 listeners recover better though disruption is equivalent. Two similar prior studies produced discrepant results: Equivalent noise effects for L1 and L2 Dutch listeners, versus larger effects for L2 Spanish than L1. To explain this, the latter experiment was presented to listeners from the former population. Larger noise effects on consonant identification emerged for L2 Dutch than L1 listeners, suggesting that task factors rather than L2 population differences underlie the results discrepancy.
