Purpose: Children with dysarthria secondary to cerebral palsy may experience reduced speech intelligibility and diminished communicative participation. However, minimal research has been conducted examining the outcomes of behavioral speech treatments in this population. This study examined the effect of Speech Intelligibility Treatment (SIT), a…

Using an identification task, we examined lexical effects on the perception of vowel duration as a cue to final consonant voicing in 12 children with specific language impairment (SLI) and 13 age-matched (6;6-9;6) peers with typical language development (TLD). Naturally recorded CVtsets [word-word (WW), nonword-nonword (NN), word-nonword (WN) and…

Children with dysarthria due to cerebral palsy (CP) present with decreased vowel space area and reduced word intelligibility. Although a robust relationship exists between vowel space and word intelligibility, little is known about the intelligibility of vowels in this population. This exploratory study investigated the intelligibility of American…

Because the environment often includes multiple sounds that overlap in time, listeners must segregate a sound of interest (the auditory figure) from other co-occurring sounds (the unattended auditory ground). We conducted a series of experiments to clarify the principles governing the extraction of auditory figures. We distinguish between auditory…

Two experiments investigated the mechanism by which listeners adjust their interpretation of accented speech that is similar to a regional dialect of American English. Only a subset of the vowels of English (the front vowels) were shifted during adaptation, which consisted of listening to a 20-min segment of the "Wizard of Oz." Compared…

We examined the performance of sequential bilingual children with and without Specific Language Impairment (SLI), who had Spanish as an L1 and English as their L2, on an auditory non-word repetition task using Spanish phonotactic patterns. We also analyzed the accuracy with which this task distinguished these children (according to children's and…

The involvement of syllables in the perception of spoken English has traditionally been regarded as minimal because of ambiguous syllable boundaries and overriding rhythmic segmentation cues. The present experiments test the perceptual separability of syllables and vowels in spoken English using the migration paradigm. Experiments 1 and 2 show…

This transcript of and guide to a two-cassette course designed to assist New Yorkers in erasure of their accents can be used for either individual or group study. Narrative and taped demonstrations of Standard American English that pinpoint typical phonological barriers and pronunciation difficulties are outlined. The author's own system of…
