| Abstract | [Introduction] In this chapter we review the various factors that may influence the location of phonetic category boundaries on physical-stimulus continua of the kind widely used in speech-perception research. These factors range from the context provided by other stimuli in a test (which gives rise to effects such as sequential contrast, range-frequency shifts, and selective adaptation) to the internal structure of a single speech stimulus (effects of other cues or features present, of adjacent phonetic segments, of speaking rate and speaker characteristics) to the listener’s linguistic experience and expectations (effects of semantic and syntactic structure, and of cross-language phonetic differences). We conclude that phonetic category boundaries are flexible in a way that suggests that speech perception is constrained by tacit knowledge of what a vocal tract does when it makes linguistically significant gestures. |
