64. 63 articulatory phonetics and phonology epilogue current technological developments permit in-depth study of speech production articulatory organization can be viewed as underlying phonological structure much phonological variation can be accounted for by simple articulatory mechanisms that are not disimilar to other motor-control activities a variety of data can be obtained with relatively simple techniques much remains to be investigated…
