Citation: Farquharson K (2015) Language or motor: reviewing categorical etiologies of speech sound disorders. Children with speech sound disorders (SSDs) exhibit marked weakness with accurate production of age-appropriate speech sounds (Lewis et al., 2006). For some of these children, the etiology of the SSD is clear (e.g., cleft palate, a genetic syndrome, or hearing loss). For others, the cau...

background: previous studies have shown that interaural-time-difference (itd) training can improve localization ability. surprisingly little is, however, known about localization training vis-à-vis speech perception in noise based on interaural time difference in the envelope (itd env). we sought to investigate the reliability of an itd env-based training program in speech-in-noise perception a...

PURPOSE To develop a system for numerically quantifying a speaker's phonetic accuracy through transcription-based measures. With a focus on normal and disordered speech in children, the authors describe a system for differentially weighting speech sound errors on the basis of various levels of phonetic accuracy using a Weighted Speech Sound Accuracy (WSSA) score. The authors then evaluate the r...

PURPOSE The primary aim of this study was to examine differences in speech/language and written language skills between children with suspected childhood apraxia of speech (CAS) and children with other speech-sound disorders at school age. METHOD Ten children (7 males and 3 females) who were clinically diagnosed with CAS (CAS group) were followed from the preschool years (ages 4-6) to school ...
