One of a series of semi-annual reports, this publication contains 18 articles which report the status and progress of studies on the nature of speech, instruments for its investigation, and practical applications. Articles are as follows: "The Emergence of Native-Language Phonological Influences in Infants: A Perceptual Assimilation Mode" (Catherine T. Best); "Intonational Differences between the Reduplicative Babbling of French- and English-Learning Infants" (D. H.
