Electropalatography and the Linguagraph system

Area of Science:

• Speech-language pathology
• Biomedical engineering
• Clinical audiology

Background:

• Electropalatography (EPG) is a technique used to measure tongue-palate contact.
• Objective assessment of tongue function is crucial for effective speech therapy.
• Existing methods for assessing tongue function may lack user-friendliness or objective outcome measures.

Purpose of the Study:

• To describe the development of Linguagraph, a user-friendly clinical instrument for electropalatography.
• To demonstrate the utility of Linguagraph for objective assessment of tongue function during speech.
• To present technical aspects and clinical trial results of Linguagraph for speech disorder management.

Main Methods:

• Development of the Linguagraph instrument for measuring tongue/palate contact.
• Utilizing Linguagraph for objective assessment of tongue function in a clinical setting.
• Providing visual feedback for speech therapy and objective outcome measurement using Linguagraph.

Main Results:

• Linguagraph enables objective assessment of tongue function, facilitating targeted therapy.
• The instrument provides visual feedback for therapy and allows for easy objective measurement of outcomes.
• A clinical trial demonstrated the potential usefulness of Linguagraph in assessing and managing speech disorders.

Conclusions:

• Linguagraph is a user-friendly clinical instrument for electropalatography.
• The device offers objective assessment and feedback for speech therapy.
• Linguagraph shows promise for improving the assessment and management of speech disorders.
