Background: Acquired apraxia of speech (AOS) involves speech-production deficits on both the segmental and suprasegmental levels. Recent research has identified a non-linear interaction between the metrical structure of bisyllabic words and word-production accuracy in German speakers with AOS, with trochaic words (strong-weak stress) being…

Purpose: Individuals with primary progressive apraxia of speech (PPAOS) have apraxia of speech (AOS) in which disruptions in articulation or prosody predominate the speech pattern, referred to, respectively, as phonetic or prosodic subtypes. Many develop aphasia and/or dysarthria. Past research has demonstrated that simple temporal acoustic…

In this secondary analysis study, the authors explored the relations between reading comprehension and oral reading performance in fourth-grade students, using a data set from the U.S. National Assessment of Educational Progress (NAEP) special study of oral reading. The data set consisted of 1,713 students randomly selected from the 140,000 fourth…

Purpose: Subjective speech intelligibility assessment is often preferred over more objective approaches that rely on transcript scoring. This is, in part, because of the intensive manual labor associated with extracting objective metrics from transcribed speech. In this study, we propose an automated approach for scoring transcripts that provides…

The current study investigated first language (L1) effects on listener judgment of comprehensibility and accentedness in second language (L2) speech. The participants were 45 university-level adult speakers of English from three L1 backgrounds (Chinese, Hindi, Farsi), performing a picture narrative task. Ten native English listeners used…

The present study explored how average- and high-skilled second-grade readers (as identified by their Woodcock-Johnson III Test of Academic Achievement Broad Reading scores) differed on behavioral measures of reading related to comprehension: eye movements during silent reading and prosody during oral reading. Results from silent reading implicate…

This study examined the oral reading fluency of 4th graders with respect to prosodic characteristics. Seventy 4th graders participated in the study. They were initially asked to read a grade-level passage and their reading was video recorded. Their reading errors were identified and their word correct per minute (WCPM) was determined. Their oral…

In three experiments, we tested the hypothesis that those errors in immediate serial recall (ISR) that are attributable to phonological confusability share a locus with segmental errors in normal speech production. In the first two experiments, speech errors were elicited in the repeated paced reading of six-letter lists. The errors mirrored the…
