Purpose: The purpose of the study was to determine the effect of hearing aid technology level on listener outcome measures. In addition, we aimed to determine if individual characteristics such as noise acceptance and the demands of the listening environment impacted performance and preference. Method: A repeated-measures, single-blinded research…

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)

Argues that knowing how infants process speech is a prerequisite to any definition of linguistic experience and therefore, the discrimination paradigm does not provide a test for the effect of experience on infants' speech discrimination. Outlines conditions to be met in order to conclude an effect of experience. (EKN)

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…

Discusses difficulties in perception of English /r/ and /l/ and concludes the error pattern is not predictable on the basis of contrastive phonological analysis but might be the result of acoustic-phonetic factors. (EKN)
