The contrast between alveolar and velar stops with typical speech data: acoustic and articulatory analyses.

Purpose: This study used acoustic and articulatory analyses to characterize the contrast between alveolar and velar stops with typical speech data, comparing the parameters (acoustic and articulatory) of adults and children with typical speech development.

Methods: The sample consisted of 20 adults and 15 children with typical speech development. The analyzed corpus was organized through five repetitions of each target-word (/'kap ə/, /'tapə/, /'galo/ e /'daɾə/).

Ultrasound applicability in Speech Language Pathology and Audiology.

Purpose: To present recent studies that used the ultrasound in the fields of Speech Language Pathology and Audiology, which evidence possibilities of the applicability of this technique in different subareas.

Research Strategy: A bibliographic research was carried out in the PubMed database, using the keywords "ultrasonic," "speech," "phonetics," "Speech, Language and Hearing Sciences," "voice," "deglutition," and "myofunctional therapy," comprising some areas of Speech Language Pathology and Audiology Sciences. The keywords "ultrasound," "ultrasonography," "swallow," "orofacial myofunctional therapy," and "orofacial myology" were also used in the search.

The interaction between awareness of one's own speech disorder with linguistics variables: distinctive features and severity of phonological disorder.

Purpose: To analyze the possible relationship among the awareness of one's own speech disorder and some aspects of the phonological system, as the number and the type of changed distinctive features, as well as the interaction among the severity of the disorder and the non-specification of distinctive features.

Methods: The analyzed group has 23 children with diagnosis of speech disorder, aged 5:0 to 7:7. The speech data were analyzed through the Distinctive Features Analysis and classified by the Percentage of Correct Consonants.

Occurrence of the repair strategy of stopping: relationship with phonological disorder severity and affected phonemes.

Purpose: To analyze the occurrence of the repair strategy of stopping in the different severities of phonological disorder, and to verify the phonemes most affected by this strategy.

Methods: Participants were 33 children, 14 female and 19 male, aged between 4 and 8 years. All children used the repair strategy of stopping for at least one phoneme or allophone, with percentage equal to or greater than 40%.
