“…With the exception of the latter finding, the remaining agreement percentages, ranging from low 70% values to high 90% values, are as high or higher than transcription reliability findings reported in prior reviews of the literature and in our laboratory (McSweeny & Shriberg; 1995, Shriberg & Lof; 1991, Shriberg et al, 2005). Following is a summary of trends in the individual and mean agreement estimates shown in figure 3.…”

A companion paper describes three extensions to a classification system for pediatric speech sound disorders termed the Speech Disorders Classification System (SDCS). The SDCS uses perceptual and acoustic data reduction methods to obtain information on a speaker's speech, prosody, and voice. The present paper provides reliability estimates for the two perceptual methods (narrow phonetic transcription; prosody-voice coding) and the acoustic analysis methods the SDCS uses to describe and classify a speaker's speech competence, precision, and stability. Speech samples from 10 speakers, 5 with significant motor speech disorder and 5 with typical speech, were remeasured to estimate intrajudge and interjudge agreement for the perceptual and acoustic methods. Each of the speakers completed five speech tasks (total = 50 datasets), ranging in articulatory difficulty for the speakers, with consequences for the difficulty level of data reduction. Point-to-point percentage of agreement findings for the two perceptual methods were as high or higher than reported in literature reviews and from previous studies conducted within our laboratory. Percentage of agreement findings for the acoustics tasks of segmenting phonemes, editing fundamental frequency tracks, and estimating formants ranged from values in the mid 70% to 100%, with most estimates in the mid 80% to mid 90% range. Findings are interpreted as support for the perceptual and acoustic methods used in the SDCS to describe and classify speakers with speech sound disorders.

“…Studying the raw data in detail revealed how there appeared to be a considerable difference in the coding of palatalization. Listener 1 usually categorized this as a cleft speech characteristic, in contrast to Listener 2 who categorized this more typically as a non‐cleft speech immaturity . This may be because the category non‐cleft speech immaturities was not given sufficient emphasis in training .…”

“…Shriberg et al. compared digital and analogue audio recording systems and noted a trend for the digital samples to be scored more critically compared to the analogue samples. This suggests the improved speech results are not associated with the nature of the recording medium.…”

Structured AbstractObjectivesTo describe the perceptual speech outcomes from the Cleft Care UK (CCUK) study and compare them to the 1998 Clinical Standards Advisory Group (CSAG) audit.Setting and sample populationA cross-sectional study of 248 children born with complete unilateral cleft lip and palate, between 1 April 2005 and 31 March 2007 who underwent speech assessment.Materials and methodsCentre-based specialist speech and language therapists (SLT) took speech audio–video recordings according to nationally agreed guidelines. Two independent listeners undertook the perceptual analysis using the CAPS-A Audit tool. Intra- and inter-rater reliability were tested.ResultsFor each speech parameter of intelligibility/distinctiveness, hypernasality, palatal/palatalization, backed to velar/uvular, glottal, weak and nasalized consonants, and nasal realizations, there was strong evidence that speech outcomes were better in the CCUK children compared to CSAG children. The parameters which did not show improvement were nasal emission, nasal turbulence, hyponasality and lateral/lateralization.ConclusionThese results suggest that centralization of cleft care into high volume centres has resulted in improvements in UK speech outcomes in five-year-olds with unilateral cleft lip and palate. This may be associated with the development of a specialized workforce. Nevertheless, there still remains a group of children with significant difficulties at school entry.

“…The transcripts were formatted so that analysis could be carried out using the previously described SDCS (Shriberg et al, 1997b). Transcription agreement estimates for the samples and transcribers used in the current study are reported elsewhere (Shriberg & Lof, 1991;McSweeny & Shriberg, 1995;Shriberg et al, 2005).…”

Measuring the intelligibility of conversational speech in children

Conversational speech is the most socially-valid context for evaluating speech intelligibility, but it is not routinely examined. This may be because it is difficult to reliably count the number of words in the unintelligible portions of the sample. In this study four different approaches to dealing with this problem are examined. Each is based on the assumption that it is possible to perceive syllables in unintelligible strings even when the target words are unknown; these unintelligible syllables can then be used to estimate the number of unintelligible words in these samples using at least four different approaches. Preliminary data are presented for each of the four approaches based on conversational speech from two convenience samples including 320 children with normal (or normalized) speech and 202 children with speech delay. Differences among the four approaches are discussed.
