“…In keeping with the original purpose for developing the TOCS, initial evaluation of its reliability (delayed alternate forms, inter-rater) (Hodge & Gotzke, 2010) and criterion-related validity (Hodge & Gotzke, 2014) has focused only on children with developmental dysarthria and CP. CP is the is the most common neurodisability in children (Msall & Park, 2009) and developmental dysarthria has been identified as the most frequently occurring motor speech disorder in these children (Webb & Adler, 2008).…”

“…Yorkston and Beukelman (1981) reported that IWPM (a measure that combines intelligibility and rate) provides a more sensitive measure of disorder severity than intelligibility scores alone for adults with acquired dysarthria. Hodge and Gotzke (2014) reported that when both rate and intelligibility scores are taken into consideration, the TOCS imitated sentence sample provides a more discriminating measure of severity of speech disorder for children with CP and speech impairment than intelligibility scores alone. However it is not known how IWPM scores compare among children with typically developing speech, speech sound disorder of unknown origin and children with CP and dysarthria.…”

a,bPurpose: We examined variability of speech intelligibility scores and how well intelligibility scores predicted group membership among 5-year-old children with speech motor impairment (SMI) secondary to cerebral palsy and an agematched group of typically developing (TD) children. Method: Speech samples varying in length from 1-4 words were elicited from 24 children with cerebral palsy (mean age 60.50 months) and 20 TD children (mean age 60.33 months). Two hundred twenty adult listeners made orthographic transcriptions of speech samples (n = 5 per child). Results: Variability associated with listeners made a significant contribution to explaining the variance in intelligibility scores for TD and SMI children, but the magnitude was greater for TD children. Intelligibility scores differentiated very well between children who have SMI and TD children when intelligibility was at or below approximately 75% and above approximately 85%. Conclusions: Intelligibility seems to be a useful clinical tool for differentiating between TD children and children with SMI at 5 years of age; however, there is considerable variability within and between listeners, highlighting the need for more than one listener per child to ensure validity of an intelligibility measure.

“…The majority of speech-oriented treatments for CAS make the (usually implicit) assumption that if overall accuracy and consistency improve, then the improvements will carry over to intelligibility. 22,[26][27] This relationship between speech accuracy and intelligibility has been studied in other speech disorders. 26,28 For example, for children with dysarthria secondary to cerebral palsy, none of the measures of accuracy (e.g., percent consonants correct [PCC], percent vowels correct [PVC], percent whole-word accuracy [PWWA]) correlated significantly with word intelligibility.…”

Background: Childhood apraxia of speech (CAS) is a pediatric speech disorder that significantly affects communication and life participation. Most CAS treatment research uses speech accuracy as primary outcome measure, on the assumption that accuracy predicts communicative success. However, this relationship has not yet been examined in this population, limiting our understanding of the impact of available treatments. Purpose: The purpose of this study is to explore the relationship between speech accuracy and intelligibility in children with CAS. Intelligibility is defined here as the proportion of words correctly understood by an unfamiliar listener. Methods: Adult listeners, who were unfamiliar with children with CAS, listened to recordings of children with CAS producing single words, and typed what they heard the child say. Separately, and prior to the listening experiment, the children’s words were scored for accuracy using various measures, including the percent phonemes (sounds) correct (PPC), percent consonants correct (PCC), and percent vowels correct (PVC). The relationship between these accuracy measures and intelligibility were examined descriptively. Results: Preliminary findings suggest that there is a positive relationship between intelligibility and PPC and PCC in children with CAS. Conclusions: Implications of these findings for clinical practice as well as future treatment research are discussed.
