Abstract : The research conducted during the first year of funding addressed fundamental issues in the perception and internal representation of speech. Three separate lines of research were designed to clarify the relationship between low-level (phonemic) speech codes and higher-level (lexical) ones. Two of the approaches involved tests of whether the activation of a lexical (word) representation increases the activation of its components (i.e., the phonemes that compose it). One of these lines investigated the extent to which listeners perceptually restore deleted phonemes, while the other examined how rapidly listeners can detect a pre-specified phenomena. The third line of research tested whether the existence of one lexical representation (e.g., 'tent'). Together, the various investigations are intended to clarify the structure and processes of the human speech perceptual system.
