Assesses the relationship between production deficits and speech perception abilities. A categorical perception paradigm was administered to a group of communication disordered children and to a matched control group. Group results are tentatively interpreted as showing a moderate perceptual deficit in the communication disordered children of this…

An experiment tests conjectures that right ear advantage (REA) has an auditory origin in competition or interference between acoustically similar stimuli and that feature-sharing effect (FSE) has its origin in assignment of features of phonetically similar stimuli. No effect on the REA for acoustic similarity, and a clear effect of acoustic…

Investigates the phenomenon that subjects speaking under exposure to masking noise demonstrate decreases in oral sensory function and temporal reorganization of the articulatory pattern. The study attempts to measure the effects of this phenomenon under varying durations of exposure to auditory masking. (Author/NCR)

Argues that generative phonology is not predictive of phonological identification, thus preventing it from achieving descriptive adequacy and limiting its value in explaining human speech perception. The assumption that the unity of the morpheme must be expressed phonologically is rejected. (Author/EJS)

Reports a study which shows that subjects can make discriminative judgments of a speaker's height and weight from his tape recorded speech. This ability is not altered by the filtering of the speech signal. (PMJ)

Reports a study showing that subjects can make discriminative judgments about a speaker's sex and race from his tape-recorded speech. Filtering the speech signal adversely affects race but not sex identification. Listener accuracy and confidence for sex judgments are greater than for race judgments. (PMJ)

Investigates the effects of morphological boundaries and the voicing characteristics of the following consonant on the duration of stressed vowels produced by hearing impaired adults. They do not vary the duration of stressed vowels in accordance with the durational recording observed in normal speech; however, this deviance is systematic. (PMJ)
