Electropalatography
Electropalatography (EPG) is an instrumental method for measuring tongue-to-palate contact during speech by using a specially designed artificial palate fitted with an array of sensors. Developed by William John Hardcastle in the 1970s, EPG provides detailed real-time visualization of articulation and has applications in phonetic research, speech pathology assessment, and biofeedback training. The method enables precise documentation of articulatory patterns across languages and is especially valuable for analyzing consonants that require palatal contact.
