This report is one of a regular series about the status and progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. The 11 papers discuss the dissociation of spectral and temporal cues to the voicing distinction in initial stopped consonants; perceptual integration and selective attention in speech perception; phonetic recoding and reading difficulty in beginning readers; interactive experiments with a digital pattern playback; the function of strap muscles in speech; the geniohyoid and the role of the strap muscles; syllable synthesis; articulatory movements in vowel-consonant-vowel sequences; measuring laterality effects in dichotic listening; a simple model of response selection in the dichotic two-response paradigm; and acoustic correlates of perceived prominence in unknown utterances. Other sections list publications and reports from Haskins Laboratories and the Defense Documentation Center and the ERIC numbers of earlier reports. (AA)
