First International Conference on Spoken Language Processing (ICSLP 90)
Over 30 years of research has shown that speech perception requires attention and effort. In addition, more recent studies have shown that speech recognition is not carried out by a fixed perceptual system: Perceptual learning of speech takes place even in adult listeners. In spite of these findings, most theories of speech perception do not incorporate mechanisms of learning or attention. Perhaps the absence of these mechanisms may explain why theories of speech perception have been unable to provide a sufficient account of our ability to recognize the linguistic structure of spoken language. Recent research suggests that a linkage between perceptual learning and attention may provide the basis for a new, cognitive theory of speech perception that can explain our ability to understand spoken language.
