Supplements Hans Basboll's state-of-the-art report on generative phonology (EJ 227 659), focusing on "abstract" v "concrete" approaches to surface data. Includes a summary of a discussion on phonology. (RL)

Contains status reports of research in three areas of speech production: functional properties of the speech production apparatus, control principles underlying speech production, and the biological basis of the speech production process. (RL)

Outlines an approach for studying auditory levels in speech perception, focusing on the artificial speech understanding system that is most compatible with the experimental data obtained in speech perception research. (RL)

Augments Michael Studdert-Kennedy's state-of-the-art report on speech perception research (EJ 227 656) with comments on categorical perception of speech and nonspeech stimuli, speech perception in context, the role of prosody, and development/impairments of speech perception. Includes a summary of a discussion on speech perception research. (RL)

Reviews research on prosody and segmental perception, segmentation and invariance, categorical perception of speech and nonspeech, feature detectors, scaling speech sounds to an auditory-articulatory space, acoustic-phonetic dependencies within the syllable, higher order (nonphonetic) factors in the comprehension of fluent speech, and cerebral…
