Status Report on Speech Research: A Report on the Status and Progress of Studies on the Nature of Speech, Instrumentation for Its Investigation, and Practical Applications, January-June 1987

摘要

The report (1 January-30 June 1987) is one of a regular series on the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Manuscripts cover the following topics: integration and segregation in speech perception; evidence of talker-independent information for vowels; controlled variables in sentence intonation; articulatory synthesis: numerical solution of a hyperbolic differential equation; type and number of violations and the grammatical congruency effect in lexical decision; low constraint facilitation in lexical decision with single word contexts; use of morphological knowledge in spelling derived forms by learning-disabled and normal students; development of morphological knowledge in relation to early spelling ability; crossword puzzle paradigm: the effectiveness of different word fragments as cues for the retrieval of words; the possible role of auditory short-term adaptation in perception of the prevocalic (m)-(n) contrast; difference in second-formant transitions between aspirated and unaspirated stop consonants preceding (alpha); sensitivity to inflectional morphology in agrammatism: investigation of a highly-inflected language; intentionality: a problem of multiple reference frames, specificational information, and extraordinary boundary conditions on natural law.
