“…Results from these studies (Ertmer & Goffman, 2011;Faes & Gillis, 2018;Ingram et al, 2001; Moreno-Torres, 2014) are generally consistent; each reports increased rates of whole-word variability in children with CIs when compared to their peers matched on a variety of different variables. Ertmer and Goffman (2011) reported higher rates of variability in children with 2 years of hearing experience relative to their chronological age-matched peers, Ingram et al (2001) reported significantly higher variability in children with CIs with between 1 and 4 years of hearing experience relative to a peer group matched on phonological ability (i.e., consonant accuracy and phonemic inventory), and Moreno-Torres (2014) found greater whole-word variability in Spanish-speaking children with CIs who had 1-1.5 years of hearing experience compared to a peer group matched on expressive language ability.…”

“…Ertmer & Goffman, 2011), and disproportionally more problems with certain phonemes such as the velar nasal and /t/ compared to their typically developing peers with NH (Flipsen, 2011). Additionally, previous studies have found increased rates of whole-word variability in monolingual children who use CIs (Chin, 2003;Chin & Pisoni, 2000;Ertmer & Goffman, 2011;Faes & Gillis, 2018;Ingram, McCartney, Bunta, Costa, & Freitas, 2001;Moreno-Torres, 2014).…”

“…In order to investigate whether production stability emerges as a result of increased CI experience within an individual child, a longitudinal study assessing rates of whole-word variability in words of comparable phonetic complexity over time would be needed. Faes and Gillis (2018) began to get at this question in their longitudinal study of children with CIs up to the age of 5;0 and found that whole-word variability decreased as children got older. Because their variability rates were based on spontaneous speech samples, however, they were not able to control for the phonetic complexity of the words.…”

This study investigates consonant and vowel accuracy and whole-word variability (also called token-totoken variability or token-to-token inconsistency) in bilingual Spanish-English and monolingual English-speaking children with cochlear implants (CIs) compared to their bilingual and monolingual peers with normal hearing (NH). Method: Participants were 40 children between 4;6 and 7;11 (years;months; M age = 6;2), n = 10 each in 4 participant groups: bilingual Spanish-English with CIs, monolingual English with CIs, bilingual Spanish-English with NH, and monolingual English with NH. Spanish and English word lists consisting of 20 words of varying length were generated, and 3 productions of each word were analyzed for percent consonants correct, percent vowels correct, and the presence of any consonant and/or vowel variability. Results: Children with CIs demonstrated lower accuracy and more whole-word variability than their peers with NH. There were no differences in rates of accuracy or whole-word variability between bilingual and monolingual children matched on hearing status, and bilingual children had lower accuracy and greater whole-word variability in English than in Spanish. Conclusions: High rates of whole-word variability are prevalent in the speech of children with CIs even after many years of CI experience, and bilingual language exposure does not appear to negatively impact phonological development in children with CIs. Contributions to our understanding of underlying sources of speech production variability and clinical implications are discussed.

“…It has been stated, however, that from the findings hitherto reported it is not possible to conclude straightforwardly the existing relationship between variable articulatory movements and segmental level inconsistency (Vuolo & Goffman, 2016). Moreover, at phonemic level measures, no relationships have been found in typically developing preschool-aged children between either overall articulatory/phonological skills or phonological complexity of the target word and intra-word variability (Faes & Gillis, 2018;Macrae & Sosa, 2015;Martikainen et al, 2019). To the best of our knowledge, this factor has not previously been studied among children with SSD.…”

“…Overall intra-word variability has been reported to decrease after the toddler years among TD children (Faes & Gillis, 2018;Holm, Crosbie, & Dodd, 2007;Martikainen et al, 2019;Sosa, 2015). However, variability scores found in the studies have ranged remarkably, possibly due to differences in the phonology and syllable and word structures of the target languages, as well as in the study procedures: among 3+ years the figures vary from 12% to 62%, 4+ years from 6% to 39%, and 5+ years from 4% to 36%.…”

Intra-word accuracy and consistency in Finnish-speaking children with speech sound disorder compared to their typically developing peersThis study examined intra-word accuracy and consistency in 32 preschool-aged Finnish-speaking children with speech sound disorder (SSD) compared to their typically developing (TD) age-and gendermatched peers. Accuracy and consistency of speech production were assessed by a picture-naming task repeated three times in one assessment session. Responses were classified into four categories: 1) consistently correct, 2) consistently incorrect, 3) variable with hits (when a child's variable responses included at least one matched with the adult target), and 4) variable with no hits (when responses included at least two different response types without the matched adult target). In addition, relationships between intra-word accuracy and consistency and children's receptive vocabulary knowledge and articulatory ability based on spontaneous speech samples were investigated. The findings showed that the children with SSD produced significantly more often 'consistently incorrect' and 'variable with no hits' responses than the TD children. There was a significant negative correlation between 'variable with no hits' responses and receptive vocabulary knowledge and articulatory abilities among the children with SSD. As intra-word accuracy and consistency has not previously been studied in Finnish children with SSD, the findings highlighted the need for drafting guidelines for assessment and intervention by paying close attention to 2 high intra-word variability without correct word forms already from age three onwards.

Purpose This study examines intraword variability in 40 typically developing French-speaking monolingual and bilingual children, aged 2;6–4;8 (years;months). Specifically, it measures rate of intraword variability and investigates which factors best account for it. They include child-specific ones such as age, expressive vocabulary, gender, bilingual status, and speech sound production ability, and word-specific factors, such as phonological complexity (including number of syllables), phonological neighborhood density (PND), and word frequency. Method A variability test was developed, consisting of 25 words, which differed in terms of phonological complexity, PND, and word frequency. Children produced three exemplars of each word during a single session, and productions of words were coded as variable or not variable. In addition, children were administered an expressive vocabulary test and two tests tapping speech motor ability (oral motor assessment and diadochokinetic test). Speech sound ability was also assessed by measuring percent consonants correct on all words produced by the children during the session. Data were entered into a binomial logistic regression. Results Average intraword variability was 29% across all children. Several factors were found to predict intraword variability including age, gender, bilingual status, speech sound production ability, phonological complexity, and PND. Conclusions Intraword variability was found to be lower in French than what has been reported in English, consistent with phonological differences between French and English. Our findings support those of other investigators in indicating that the factors influencing intraword variability are multiple and reflect sources at various levels in the speech processing system.
