eletropalatografia
Eletropalatografia (electropalatography, EPG) is a technique for recording and visualizing contact between the tongue and the hard palate during speech. A thin, custom-fitted artificial palate containing an array of electrodes is placed against the roof of the mouth; when the tongue touches an electrode, a contact pattern is detected and displayed in real time or saved for analysis. The method yields time-aligned binary or grayscale matrices that represent tongue–palate contact configuration across phonetic segments.
EPG is used in clinical, educational and research contexts. Clinically, it assists assessment and therapy for
Advantages of EPG include direct articulatory information, quantifiable measures, and the possibility of real-time feedback. Limitations
