Tóm tắt	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.	Psycholinguistic Eye-Tracking is a method that measures eye movements during reading or visual processing to investigate how the mind processes language. Pioneered by Keith Rayner, eye-tracking reveals which parts of text attract attention, how long readers spend on different words, and how eye movements relate to comprehension difficulties. Metrics like fixation duration and saccade length provide objective, millisecond-level data on cognitive processing. Eye-tracking is now a standard tool for studying reading, comprehension, and attention.
