Speech Accuracy

Purpose Speech-language pathologists (SLPs) are faced with the challenge of quickly and accurately identifying children who present with speech sound disorders (SSD) compared to typically developing (TD) children. The goal of this study was to compare the clinical relevance of two speech sampling methods (single-word vs. connected speech samples) in how sensitive they are in detecting atypical speech sound development in children, and to know whether the information obtained from single-word samples is representative enough of children's overall speech sound performance. Method We compared the speech sound performance of 37 preschool children with SSD ( M age = 4;11 years) and 37 age-sex-matched typically developing children ( M age = 5;0 years) by eliciting their speech in two ways: (a) a picture-naming task to elicit single words, and (b) a story-retelling task to elicit connected speech. Four speech measures were compared across sample type (single words vs. connected speech) and across groups (SSD vs. TD): intelligibility, speech accuracy, phonemic inventory, and phonological patterns. Results Interaction effects were found between sample type and group on several speech sound performance measures. Single-word speech samples were found to differentiate the SSD group from the TD group, and were more sensitive than connected speech samples across various measures. The effect size of single-word samples was consistently higher than connected speech samples for three measures: intelligibility, speech accuracy, and phonemic inventory. The gap in sample type informativeness may be attributed to salience and avoidance effects, given that children tend to avoid producing unfamiliar phonemes in connected speech. The number of phonological patterns produced was the only measure that revealed no gap between two sampling types for both groups. Conclusions On measures of intelligibility, speech accuracy, and phonemic inventory, obtaining a single-word sample proved to be a more informative method of differentiating children with SSD from TD children than connected speech samples. This finding may guide SLPs in their choice of sampling type when they are under time pressure. We discuss how children's performance on the connected speech sample may be biased by salience and avoidance effects and/or task design, and may, therefore, not necessarily reveal a poorer performance than single-word samples, particularly in intelligibility, speech accuracy, and the number of phonological patterns, if these task limitations are circumvented. Our findings show that the performance gap, typically observed between the two sampling types, largely depends on which performance measures are evaluated with the speech sample. Our study is the first to address sampling type differences in SSD versus TD children and has significant clinical implications for SLPs looking for sampling types and measures that reliably identify SSD in preschool-aged children.

Speech sound disorders are a complex and often persistent disorder in young children. For many children, therapy results in successful remediation of the errored productions as well as age-appropriate literacy and academic progress. However, for some children, while they may attain age-appropriate speech production skills, they later have academic difficulties. For SLPs in the public schools, these children present as challenging in terms of both continuing treatment as well as in terms of caseload management. What happens after dismissal? Have these children truly acquired adequate speech production skills? Do they have lingering language, literacy, and cognitive deficits? The purpose of this article is to describe the language, literacy, and cognitive features of a small group of children with remediated speech sound disorders compared to their typically developing peers.

Good Diagnostic Accuracy

Purpose Bilingual children whose phonological skills are evaluated using measures designed for monolingual English speakers are at risk for misdiagnosis of speech sound disorders (De Lamo White & Jin, 2011). Method Forty-four children participated in this study: 15 typically developing monolingual English speakers, 7 monolingual English speakers with phonological disorders, 14 typically developing bilingual Spanish–English speakers, and 8 bilingual children with phonological disorders. Children's single-word speech productions were examined on Percentage Consonants Correct–Revised (Shriberg, Austin, Lewis, McSweeny, & Wilson, 1997a) and accuracy of early-, middle-, and late-developing sounds (Shriberg, 1993) in English. Consonant accuracy in English was compared between monolinguals and bilinguals with and without speech sound disorders. Logistic regression and receiver operating characteristic curves were used to observe diagnostic accuracy of the measures examined. Results Percentage Consonants Correct–Revised was found to be a good indicator of phonological ability in both monolingual and bilingual English-speaking children at the age of 5;0. No significant differences were found between language groups on any of the measures examined. Conclusions Our results suggest that traditional measures of phonological ability for monolinguals could provide good diagnostic accuracy for bilingual children at the age of 5;0 years. These findings are preliminary, and children younger than 5;0 years should be examined for risk of misdiagnosis.

Purpose This study investigated Icelandic-speaking children's acquisition of singleton consonants and consonant clusters. Method Participants were 437 typically developing children aged 2;6–7;11 (years;months) acquiring Icelandic as their first language. Single-word speech samples of the 47 single consonants and 45 consonant clusters were collected using Málhljóðapróf ÞM (ÞM's Test of Speech Sound Disorders). Results Percentage of consonants correct for children aged 2;6–2;11 was 73.12 ( SD = 13.33) and increased to 98.55 ( SD = 3.24) for children aged 7;0–7;11. Overall, singleton consonants were more likely to be accurate than consonant clusters. The earliest consonants to be acquired were /m, n, p, t, j, h/ in word-initial position and /f, l/ within words. The last consonants to be acquired were /x, r, r̥, s, θ, n̥/, and consonant clusters in word-initial /sv-, stl-, str-, skr-, θr-/, within-word /-ðr-, -tl-/, and word-final /-kl̥, -xt/ contexts. Within-word phonemes were more often accurate than those in word-initial position, with word-final position the least accurate. Accuracy of production was significantly related to increasing age, but not sex. Conclusions This is the first comprehensive study of consonants and consonant cluster acquisition by typically developing Icelandic-speaking children. The findings align with trends for other Germanic languages; however, there are notable language-specific differences of clinical importance.

AbstractInvestigating children's feelings and attitudes toward talking assists speech–language pathologists (SLPs) to understand experiences of communication and the impact of speech sound disorders (SSD). This, in turn, can assist SLPs in identifying appropriate intervention for children with SSD that addresses the needs of children, and their communication partners. This paper draws on data from the Sound Start Study in Australia to explore the attitudes toward talking of 132 preschool-aged children with SSD and the relationship between children's attitudes, speech accuracy, and parent-reported intelligibility and participation. The study revealed most of the children with SSD had a positive attitude toward talking. There was a significant relationship between children's attitudes toward talking and speech accuracy. Furthermore, there was a significant relationship between speech accuracy and parents' perceptions of intelligibility and participation. However, there was no significant relationship between children's attitudes and parents' perceptions. These results highlight similarities and differences between attitudes and experiences of preschool-aged children, their performance on clinical measures, and their parents' perceptions, indicating the need for SLPs to consider each of these areas during assessment and intervention.

AbstractTypical morpho-phonological measures of children’s speech realizations used in the literature depend linearly on their components. Examples are the proportion of consonants correct, the mean length of utterance and the phonological mean length of utterance. Because of their linear dependence on their components, these measures change in proportion to their component changes between speech realizations. However, there are instances in which variable speech realizations need to be differentiated better. Therefore, a measure which is more sensitive to its components than linear measures is needed. Here, entropy is proposed as such a measure. The sensitivity of entropy is compared analytically to that of linear measures, deriving ranges in component values inside which entropy is guaranteed to be more sensitive than the linear measures. The analysis is complemented by computing the entropy in two children’s English speech for different categories of word complexity and comparing its sensitivity to that of linear measures. One of the children is a bilingual typically developing child at age 3;0 and the other child is a monolingual child with speech sound disorders at age 5;11. The analysis and applications demonstrate the usefulness of the measure for evaluating speech realizations and its relative advantages over linear measures.

Purpose The purpose of this article is to quantify and describe stuttering-like disfluencies in speakers with acquired apraxia of speech (AOS), utilizing the Lidcombe Behavioural Data Language (LBDL). Additional purposes include measuring test–retest reliability and examining the effect of speech sample type on disfluency rates. Method Two types of speech samples were elicited from 20 persons with AOS and aphasia: repetition of mono- and multisyllabic words from a protocol for assessing AOS (Duffy, 2013), and connected speech tasks (Nicholas & Brookshire, 1993). Sampling was repeated at 1 and 4 weeks following initial sampling. Stuttering-like disfluencies were coded using the LBDL, which is a taxonomy that focuses on motoric aspects of stuttering. Results Disfluency rates ranged from 0% to 13.1% for the connected speech task and from 0% to 17% for the word repetition task. There was no significant effect of speech sampling time on disfluency rate in the connected speech task, but there was a significant effect of time for the word repetition task. There was no significant effect of speech sample type. Conclusions Speakers demonstrated both major types of stuttering-like disfluencies as categorized by the LBDL (fixed postures and repeated movements). Connected speech samples yielded more reliable tallies over repeated measurements. Suggestions are made for modifying the LBDL for use in AOS in order to further add to systematic descriptions of motoric disfluencies in this disorder.

An investigation was conducted to compare the effects of single word and connected speech sampling conditions on the production of consonant clusters. Speech samples were obtained from 40 children with speech sound impairments who were aged 3 years: 6 months to 5 years. The children’s productions of 36 commonly occurring consonant clusters were compared across the two sampling conditions. Overall, children’s productions were more similar than different. Differences between the sampling conditions were apparent for three of the eight phonological processes studied, namely, cluster reduction, final consonant deletion, and epenthesis. Of 12 fine phonetic variations, only aspirated stops showed a significant difference between the sampling conditions. There was a wide range of individual variation.

Purpose The purpose of this study was to examine the diagnostic accuracy of traditional measures of phonological ability developed for monolingual English-speaking children with their bilingual peers in both English and Spanish. We predicted that a composite measure, derived from a combination of English and Spanish phonological measures, would result in higher diagnostic accuracy than examining the individual phonological measures of bilingual children separately by language. Method Sixty-six children, ages 3;3–6;3 (years;months), participated in this study: 29 typically developing bilingual Spanish-English–speaking children ( x = 5;3), five bilingual Spanish-English–speaking children with speech sound disorders ( x = 4;6), 26 typically developing monolingual English-speaking children ( x = 4;8), and six monolingual English-speaking children with speech sound disorders ( x = 4;9). Children were recorded producing single words using the Assessments of English and Spanish Phonology, and productions were phonetically transcribed and analyzed using the Logical International Phonetics Program. Overall consonants correct–revised; accuracy of early-, middle-, and late-developing sounds; and percent occurrence of phonological error patterns in both English and Spanish were calculated. Receiver operating characteristic curves and support vector machine models were applied to observe diagnostic accuracy, separately and combined, for each speaker group and each language. Results Findings indicated the combination of measures improved diagnostic accuracy within both the English and Spanish of bilingual children and significantly increased accuracy when measures from both languages of bilingual children were combined. Combining measures for the productions of monolingual English-speaking children did not increase diagnostic accuracy. Conclusion To prevent misdiagnosis of speech sound disorders in bilingual preschoolers, the composite phonological abilities of bilingual children need to be assessed across both gross and discrete measures of phonological ability.
