The Third

Many attempts have been made to teach native Japanese listeners to perceptually differentiate English /r–l/ (e.g.rock–lock). Though improvement is evident, in no case is final performance native English-like. We focused our training on the third formant onset frequency, shown to be the most reliable indicator of /r–l/ category membership. We first presented listeners with instances of synthetic /r–l/ stimuli varying only in F3 onset frequency, in a forced-choice identification training task with feedback. Evidence of learning was limited. The second experiment utilized an adaptive paradigm beginning with non-speech stimuli consisting only of /r/ and /l/ F3 frequency trajectories progressing to synthetic speech instances of /ra–la/; half of the trainees received feedback. Improvement was shown by some listeners, suggesting some enhancement of /r–l/ identification is possible following training with only F3 onset frequency. However, only a subset of these listeners showed signs of generalization of the training effect beyond the trained synthetic context.

Perceptual Impairment

This article reviews the literature on auditory perceptual impairments in children with language disorders. It is suggested that, rather than a higher-order cognitive or "linguistic" deficit, the underlying deficit in childhood language disorders is a perceptual one. The perceptual impairment may consist of a deficiency in detecting acoustic features in the speech wave that normally cue certain phonemes. Support for this hypothesis comes from clinical observations and experimental studies of aphasic adults as well as language-disordered children. The most consistent finding of the studies with language-disordered children has been that they have difficulty making perceptual judgments of the order of rapid sequences of brief sounds, such as synthetic speech and non-speech stimuli. However, these children perceive the sequences more accurately if the duration of the stimuli or the inter-stimulus intervals are extended. This suggests a "rate-specific" auditory perceptual deficit in language-disordered children for rapid acoustic information, such as the distinctive acoustic features of speech sounds. Treatment and future research implications are discussed.

Stimulus Train

Short-term habituation of the vertex auditory evoked response was studied in six infants (age 10 to 14 weeks). The infants were presented trains of four synthetic speech stimuli. The average amplitude of the evoked responses was largest to the first member of the stimulus train and then decreased rapidly. The average amplitudes to the second, third, and fourth stimuli in the train were 36, 41, and 22% of the first stimulus amplitude, respectively. The results suggest that the auditory evoked response of awake infants satisfies several of the criteria for short-term habituation.

Impaired Children

6 language-impaired misarticulating and 6 normal kindergarten children produced and perceived differences in word-initial stop consonant voicing. Individuals' productive and perceptual phonemic boundaries were similar. No statistically reliable differences were noted between the groups' mean productive or perceptual boundaries. Individual exceptions suggest that some misarticulating, language-impaired children may be inordinately challenged by synthetic speech stimuli or may pass through a developmental stage in which perceptual ability outstrips productive ability.
