This review examines research on speech perception by both native and non-native listeners. The development of speech
perception in infancy is first considered and a theoretical model that accounts for this is introduced. A brief overview then
follows of several research areas under the umbrella of non-native speech perception, namely cross-dialect, cross-language
and second-language speech perception. It is shown that non-native and native speech perception is critically shaped by the
specific ways in which speakers use acoustic cues in speech production.
