Introduction: Children with speech sound disorders (SSDs) who present the devoicing of plosive and/or fricative sounds may have difficulties with glottal respiratory control.
Objective: To analyze acoustic vocal measures, spectrographic aspects and the risk of dysphonia among children with devoicing SDDs and compare the results with those of other groups of children.
Methods: Twenty-five boys aged between six and 12 years participated.
Purpose: Describe and correlate phonological and complementary measures regarding aerodynamics, electroglottography, acoustics, and perceptual judgment of production of the voiced fricative sound /ʒ/ comparing the performance of Brazilian Portuguese-speaking children with and without speech sound disorders.
Methods: Study participants were 30 children aged 5 years to 7 years and 11 months divided into a group of children with typical development - Control Group (CG) and a group of children with speech sound disorders - Research Group (RG). Phonology (PCC, PCC-R, and occurrence of phonological processes) and the aerodynamic (amplitude of the oral airflow and f0), eletroglottographic (open quotient) and acoustic (classification of voicing) measures were evaluated.
Purpose: The purpose of the study was to determine the sensitivity and specificity, and to establish cutoff points for the severity index Percentage of Consonants Correct - Revised (PCC-R) in Brazilian Portuguese-speaking children with and without speech sound disorders.
Methods: 72 children between 5:00 and 7:11 years old - 36 children without speech and language complaints and 36 children with speech sound disorders. The PCC-R was applied to the figure naming and word imitation tasks that are part of the ABFW Child Language Test.
Objective: To identify a cutoff value based on the Percentage of Consonants Correct-Revised index that could indicate the likelihood of a child with a speech-sound disorder also having a (central) auditory processing disorder .
Methods: Language, audiological and (central) auditory processing evaluations were administered. The participants were 27 subjects with speech-sound disorders aged 7 to 10 years and 11 months who were divided into two different groups according to their (central) auditory processing evaluation results.
Introduction: Considering the importance of auditory information for the acquisition and organization of phonological rules, the assessment of (central) auditory processing contributes to both the diagnosis and targeting of speech therapy in children with speech sound disorders.
Objective: To study phonological measures and (central) auditory processing of children with speech sound disorder.
Methods: Clinical and experimental study, with 21 subjects with speech sound disorder aged between 7.
Purpose: To describe the tongue shape for /s/ and /∫/ sounds in three different groups of children with and without speech sound disorder.
Methods: The six participants were divided into three groups: Group 1--two typically developing children, Group 2--two children with speech sound disorder presenting any other phonological processes but not the ones involving the production of the /∫/ and Group 3--two children with speech sound disorder presenting any phonological processes associated to the presence of the phonological process of palatal fronting (these two children produced /∫/ as /s/) aged between 5 and 8 years old, all speakers of Brazilian Portuguese. The data were the words /'∫avi/ (key) and /'sapu/ (frog).
Purpose: To verify the performance of children with and without speech sound disorder in oral motor skills measured by oral diadochokinesia according to age and gender and to compare the results by two different methods of analysis.
Methods: Participants were 72 subjects aged from 5 years to 7 years and 11 months divided into four subgroups according to the presence of speech sound disorder (Study Group and Control Group) and age (<6 years and 5 months and >6 years and 5 months). Diadochokinesia skills were assessed by the repetition of the sequences 'pa', 'ta', 'ka' and 'pataka' measured both manually and by the software Motor Speech Profile®.
Background: Phonological disorder is one of the most frequent speech and language deficit observed in children and therefore studies using objective evaluation measurements should be developed and implemented during the diagnostic process.
Aim: To describe the acoustic characteristics of /l/ and /r/ liquid sounds.
Method: Speech production samples of 20 children with and without phonological disorder were gathered and acoustically analyzed.
