Guided Articulation Treatment with Supplemental Visual Feedback

The field of speech-language pathology is in need of improved articulation treatment methods that are more effective in implementation and treatment outcomes. Research is currently developing regarding the effectiveness of visual feedback forms (i.e., spectrogram, electropalatography, ultrasound, and visual augmented feedback) as a supplement in traditional articulation treatment. An instructional guide, titled Easy Artic, and configurable oral model were created as resources to support the current need for improved methods and materials in traditional articulation treatment, as supported by developing research. The Easy Artic guide aims to provide clinicians with a quick reference resource containing current statistics, language approaches for auditory-verbal instruction, evidence-based treatment charts, as well as examples of client education approaches. The oral model was created with metal armature, cured polymer clay, acrylic paint, and a configurable tongue for the representation of articulation placement during speech sound production. The oral model complements the Easy Artic guide, as clinicians can use the model in conjunction with activities found in the guide (e.g., Building Placement Awareness), in addition to providing clients with visual feedback for sound production in treatment. The Easy Artic guide and complementary oral model were trialed by speech-language pathologists within middle school settings in the San Dieguito Union and Vista Unified school districts. Two clinicians completed a 5-point Likert scale and open-ended survey to provide feedback on the Easy Artic guide and oral model, following the use of the resources in treatment. The results included qualitative ratings and constructive feedback that contributed to the discussion of revisions and future directions of the resources.
