Tóm tắt	Acoustic Phonetics is the study of the physical properties of speech sounds using instrumentation to measure and analyze sound waves. Pioneered by Peter Ladefoged and Kenneth Stevens, this method uses spectrograms, formant analysis, and waveform measurements to characterize vowels, consonants, and prosodic features with precision. Acoustic phonetics bridges the articulatory world of speech production and the perceptual world of listeners, providing objective, quantifiable data about how speech is produced and perceived.	Corpus Linguistics is the study of language based on large, representative collections of texts (corpora) processed by computer. Pioneered by John Sinclair and others, the method uses statistical analysis, concordancing, and computational tools to examine patterns of actual language use. Corpus linguistics has transformed our understanding of English and other languages, revealing frequency patterns, collocation preferences, and register variation that were previously hidden. It serves theoretical linguistics, applied language teaching, and natural language processing.	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.
