Purpose: A review of the salient characteristics of motor speech disorders and common assessment protocols revealed the need for a novel reading passage tailored specifically to differentiate between and among the dysarthrias (DYSs) and apraxia of speech (AOS). Method: "The Caterpillar" passage was designed to provide a contemporary, easily read,…

Purpose: To assess the feasibility and effectiveness of a newly developed assistive technology system, Lee Silverman Voice Treatment Companion (LSVT[R] Companion[TM], hereafter referred to as "Companion"), to support the delivery of LSVT[R]LOUD, an efficacious speech intervention for individuals with Parkinson disease (PD). Method: Sixteen…

Purpose: To determine (a) the effect of fundamental frequency (f0) on speech intelligibility, acceptability, and perceived gender in electrolaryngeal (EL) speakers, and (b) the effect of known gender on speech acceptability in EL speakers. Method: A 2-part study was conducted. In Part 1, 34 healthy adults provided speech recordings using…

Purpose: The purpose of this study was to evaluate adaptation to the electropalatograph (EPG) from the perspective of consonant acoustics, listener perceptions, and speaker ratings. Method: Seven adults with typical speech wore an EPG and pseudo-EPG palate over 2 days and produced syllables, read a passage, counted, and rated their adaptation to…

Purpose: This report describes the speech characteristics of individuals with a neurodegenerative syndrome called pallido-ponto-nigral degeneration (PPND) and examines the speech samples of at-risk, but asymptomatic, relatives for possible preclinical detection. Method: Speech samples of 9 members of a PPND kindred were subjected to perceptual…

Paraneoplastic cerebellar degeneration (PCD) is an autoimmune disease that can be associated with cancer of the breast, lung, and ovary. The clinical presentation of PCD commonly includes ataxia, visual disturbances, and dysarthria. The speech disturbances associated with PCD have not been well characterized, despite general acceptance that…

Purpose: This study addressed the effects of 3 different paradigms for scoring orthographic transcriptions of dysarthric speech on intelligibility scores. The study also examined whether there were differences in transcription accuracy among words from different linguistic classes. Method: Speech samples were collected from 12 speakers with…

Purpose: This pilot study explored the feasibility and effectiveness of an Internet-based telerehabilitation application for the assessment of motor speech disorders in adults with acquired neurological impairment. Method: Using a counterbalanced, repeated measures research design, 2 speech-language pathologists assessed 19 speakers with…

This study reports on the development and initial testing of the Preschool Speech Intelligibility Measure (PSIM), a single-word, multiple-choice intelligibility measure. The PSIM was adapted from the Assessment of Intelligibility of Dysarthric Speech and is designed to plot changes in children's intelligibility across time. (Author)
