Tongue movements in the production of /l/ in children with and without speech sound disorders in different ages.

Purpose: this study used the ultrasonography of the tongue movements and the dynamic models of speech production to characterize the articulatory gestures of in the production of /l/ at the Brazilian Portuguese in different age groups, comparing them between typical and atypical children.

Methods: the sample consisted of 30 typical and 30 atypical children between ages of four and eight-years-old, who underwent speech-language and ultrasonographic evaluations. The evaluation was realized by recording words reproduction with the sound /l/ and the following vocalic contexts: /a/, /i/ and /u/, repeating six times for each word.

Ultrasound analysis of tongue contour for the sound [j] in adults and children.

Purpose: Analyze and compare the mean tongue contours and articulatory gestures in the production of the sound [j] in adults and children with typical and atypical speech development. The children with atypical development presented speech sound disorders.

Methods: The diagnosis was determined by speech assessments.

Electropalatography and its correlation to tongue movement ultrasonography in speech analysis.

Purpose: To analyze the use of electropalatography and ultrasonography regarding speech therapy through literature narrative review.

Research Strategies: A literature review was conducted at PubMed and Scielo databases, using descriptors as electropalatography, electropalatography AND evaluation, electropalatography AND therapy, electropalatography AND ultrasonography, electropalatography AND speech.

Selection Criteria: The research criteria selected in the database were: studies in the past five years and studies in humans.

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.
