Auditory processing and combination of distinctive features in speech acquisition in children with phonological disorders

CONCLUSION: The results obtained in the SSW and Dichotic Listening Test showed a deficit in the abilities of complex temporal order and figure-ground, as well as lagged sensorial memory. These deficits might jeopardize the acquisition of the features described.

Severity of phonological disorder, phonological awareness and articulatory praxis in preschoolers

CONCLUSION: The RG was characterized by worse performance in phonological awareness and articulatory praxis, and by the presence of correlation between severity of the disorder, phonological awareness and articulatory praxis.

The influence of word extension and the position of speech disruption within the syllable structure in the speech of stuttering and fluent adolescents and adults

Overall, results suggest that speech disruptions occur at the beginning of words and syllables, thus indicating difficulty in synchronizing phonological selection and activation. This fact happens independently of word extension.

Extralinguistic variables, gender and age, in the self-awareness of speech impairment*

children with phonological disorder can be self-aware of speech impairment; gender and age are not important factors for the development of this ability.

Phonological disorder: aspects regarding production, perception and writing

CONCLUSION: Children can either use the compensatory lengthening strategy and not be aware of their own Speech Impairment, or be aware and not use the strategy. It was observed a possible relationship between awareness of their own speech impairment and writing hypothesis.

Perception of speech disorders: Difference between the degree of intelligibility and the degree of severity

Conclusion: There is an argument for measuring intelligibility at the surface code level with a word recognition test or ordinal scales and for allowing the use of interval scales for severity judgment.

Relapse observed in the treatment of phonological disorder*

BACKGROUND: relapse in phonological performance.
AIM: to verify relapse in the phonological performance related to sound production in the treatment of phonological disorder.
METHOD: three subjects with phonological disorders, aged 6:0, 7:0, 7:0 years, were treated for phoneme /r/ using the ABAB-Withdrawal and Multiple Probes Model. After a cycle of treatment, the phonemes that presented relapse in terms of production percentage were compared.
RESULTS: the results indicate that relapse occurred in the phonological system of all subjects. The involved features were mainly related to the main category.
CONCLUSION: a relationship between the features of the treated phoneme and the ones that presented relapse was observed for all of the studied cases.

Characterization of the speech of individuals submitted to primary palatoplasty

CONCLUSION: Most subjects presented balanced resonance or acceptable hypernasality and absence of compensatory articulation, regardless the type of cleft, surgical technique and age range, although no significant differences were found. Among the conducts adopted after the first evaluation following primary palatoplasty, speech therapy was the most frequent.

Body and oral motor aspects in a group of children with phonological delay/disorder

CONCLUSION: Phonological delay and disorder do not show significant distinction regarding motor, oral and infectious aspects, together with deleterious oral habits, as shown by the homogeneity between the groups.

Choice of target sounds for therapy: analysis focused on distinctive features

The targets of the treatment can facilitate or difficult acquisitions in the phonological inventory. This study had the aim to verify the effectiveness of the therapy proposed by the Multiple Oppositions Model, taking into consideration the target sounds chosen, as well as to analyze the acquired sounds and the distinctive features, based on the target sounds. The researched group comprised five children with phonological disorder, with an average age of 6;1 (years;months). Speech-language pathology and complementary evaluations were carried out. After the assessments, the subjects underwent speech therapy using the Multiple Oppositions Model. After treatment, another evaluation was carried out, in order to compare the therapeutic evolution and the effectiveness of the chosen sound targets for each subject. The phonological inventory and the number of altered distinctive features before and after therapy were compared for each subject, as well as the distinctive features focused during therapy. The subjects who added more phonemes to their phonological inventory were the ones that most decreased the number of altered distinctive features. It can be concluded that the Multiple Oppositions Model provided improvements on the phonological inventory that were related to the characteristics of the target sounds selected for each subject. The subjects whose target sounds contemplated the work with the majority of the altered distinctive features and the most complex sounds in the phonological hierarchy presented greater acquisitions in their phonological inventories.

The use of the compensatory lengthening strategy in different severities of phonological disorder

CONCLUSION: There was no relationship between the use of the compensatory lengthening strategy and the different phonological disorder severities. Subjects’ distribution based on the severity of the phonological disorder, according to the classifications used in the study, allowed the visualization of a correspondence between both classifications of the disorder.

Electromyography and diadochokinesia – a study with fluent and stuttering children*

the results of the study indicate that there were great similarities in performance in the DDK tasks for both groups. Standard deviation values were high for both groups. Conclusion: statistically significant differences were observed for the ability of sequential movement, i.e. when looking at ANOVA results the group of fluent children presented a better ability to move their articulators rapidly when producing sequential segments (pa/ta/ka).

Speech Disorders in Right-Hemisphere Stroke

Clinical practice shows that right-hemisphere cerebral strokes are often accompanied by one speech disorder or another. The aim of the present work was to analyze published data addressing speech disorders in right-sided strokes. Questions of the lateralization of speech functions are discussed, with particular reference to the role of the right hemisphere in speech activity and the structure of speech pathology in righthemisphere foci. Clinical variants of speech disorders, such as aphasia, dysprosody, dysarthria, mutism, and stutter are discussed in detail. Types of speech disorders are also discussed, along with the possible mechanisms of their formation depending on the locations of lesions in the axis of the brain (cortex, subcortical structures, stem, cerebellum) and focus size.

Treatment of Children With Speech Oral Placement Disorders (OPDs): A Paradigm Emerges

Epidemiological research was used to develop the Speech Disorders Classification System (SDCS). The SDCS is an important speech diagnostic paradigm in the field of speech-language pathology. This paradigm could be expanded and refined to also address treatment while meeting the standards of evidence-based practice. The article assists that process by initiating a clinical exchange of ideas on the topic of speech treatment. It explores: (a) the treatment of children with speech oral placement disorders (OPD; a new term suggested by the authors), (b) the various types of speech oral placement therapy (OPT) used to treat OPD, (c) the relationships of OPT to current motor learning theories and oral motor treatment, as well as (c) the critical need for appropriately designed, systematic research on OPT.
