“…Nevertheless, as a clinical group they performed significantly lower on all the investigated variables. This was in accordance with previous findings in different clinical groups . Even though the children in these groups are already followed within the healthcare system, their early speech and language development might not be a focus at the early age of 10 months.…”

“…Thus, the presence of CB and a high occurrence of oral stop consonants with anterior placement can be seen as good characteristics in a child's early speech and language development. Early consonant production can be affected by disabilities such as a cleft palate and hearing loss or neurodevelopmental disabilities such as cerebral palsy and autism spectrum disorders .…”

Aim: We investigated how accurate observations of canonical babbling (CB) were and explored predictive babbling measures in children with and without medical diagnoses of conditions that can lead to speech and language problems.Methods: From 2012 to 2014 this Stockholm-based study recruited 38 children aged nine months to 21 months with medical diagnoses and 30 children aged 10 months without diagnoses and included 21 previously studied 12-month-old children without medical diagnoses. CB and consonant sound production were directly observed by video recording natural play with a caregiver. The percentage of CB was calculated from each recording, and a validated observation form was used. How accurately the children with and without CB were classified was investigated with sensitivity and specificity. The groups were compared using predictive babbling variables. Results:The observation method identified children with and without CB well, with a specificity of 0.89 and sensitivity of 0.93, respectively. Children with predictive babbling measures were identified in the clinical group (specificity 0.93-0.97), and a lack of these measures indicated a risk of being in the clinical group (odds ratios > 10). The sensitivity was low (0.32-0.42). Conclusion:Observation effectively identified a lack of CB and supported the importance of assessing babbling measures.

“…15,16 Children with Down syndrome, Williams syndrome, cerebral palsy, or profound hearing impairment, however, enter this stage of verbal development with a significant delay. 16,[26][27][28] A retrospective study based on questionnaires found similar results in individuals with RTT. 29 Onset of canonical babbling was also delayed in three of our participants.…”

ABBREVIATIONSPSV Preserved speech variant RTT Rett syndrome AIM Our aim was to contribute new findings related to the pre-regressional verbal development of females with a variant of Rett syndrome (RTT) as the loss of spoken language is one of the key clinical features of RTT, and it would be of particular interest to study the early speech-language development of females who are considered to have preserved some speech-language abilities.METHOD We analysed 461 minutes of audio-video recordings containing play situations and the daily routines of six females (aged 7 to 24 months; mean birthweight 3057g, SD 195g) with the preserved speech variant (PSV) of RTT. All videos were recorded by parents and analysed retrospectively after the diagnosis PSV was made.RESULTS From the age of 7 months onwards, we observed two types of vocalizations, appearing intermittently: (1) apparently normal sequences; and (2) atypical (i.e. inhalatory, pressed, or high-pitched crying-like) vocalizations. Some participants failed to reach the milestone of canonical babbling. We observed a limited phonological and lexical complexity and a restricted compositional variability. Volubility was reduced during the whole period under observation. Hand stereotypies with simultaneous atypical vocalizations appeared only during the second year of life. INTERPRETATIONThe intermittent character of normal versus abnormal verbal behaviours might contribute to an early identification of children with a possible genetic mutation, and provides evidence that speech-language functions are abnormal from the very beginning.Rett syndrome (RTT, MIM 312750), a profoundly disabling neurodevelopmental disorder that predominantly occurs in females, is mainly caused by mutations in the gene MECP2 for the methyl-CpG-binding protein 2 (Xq28).1 It is assumed that MeCP2, a regulator of neuronal activity-dependent synaptic maturation, plays a central role in postnatal brain development. Disruption of MeCP2 affects a wide range of neurodevelopmental functions such as cognitive processes, purposeful hand use, and communicative abilities.2 The pathogenesis of RTT is characterized by a four-stage trajectory, the second of which is the regression period, in which the clinical signs become more prominent.1 The trajectory can be observed in females with classic RTT as well as in other variants of RTT, of which the so-called preserved speech variant (PSV) or Zappella variant (Z-RTT) has a more benign overall pathogenesis, including better manual and speech-language abilities. 1,3,4 Females with PSV have the same staging and a number of the same symptoms as in classic RTT (e.g. the characteristic hand stereotypies) but usually show no general growth failure or deceleration of head growth; epilepsy and hyperventilation are rare.3-5 Furthermore, individuals with PSV show a postregressional improvement in hand use; language abilities may be regained or preserved. Lexicon size and syntactic complexity are reported to increase slowly, but are usually accompanied by features such as e...

Objective: We examined whether perceived voice quality is altered in a group of children with cerebral palsy (CP) following an intervention focusing on respiration and phonation, and whether possible improvements might be associated with increased intelligibility levels. Methods: Sixteen individuals with CP and dysarthria (9 girls, mean age 14 years, SD = 2; 9 with spastic type CP, 2 dyskinetic, 4 mixed, 1 Worster-Drought syndrome) completed intelligibility assessments on separate days twice before intervention, at termination of treatment and at 6-week follow-up using 50 words from the Children's Speech Intelligibility Measure lists, and describing cartoon strips. Experienced speech-language pathologists rated voice quality employing GRBAS scales. Results: There was no clear evidence that change in voice quality pre-post intervention was large compared with change in the pre-intervention or post-intervention periods. Asthenia demonstrated largest improvement (effect size of 0.4). Intelligibility correlated weakly with Grade, Breathiness and Asthenia, but not with Roughness or Strain. A deterioration of 1 unit on the Grade and Asthenia scales was associated with an approximately 11% decrease in intelligibility. Conclusion: Perceived changes in voice quality were small compared to changes in intelligibility. Further investigations must examine other variables potentially associated with intelligibility gain to better understand the links between the respiratory-phonatory intervention and improved intelligibility.
