Louis M. Goldstein [1][2] is an American linguist and cognitive scientist. He was previously a professor and chair of the Department of Linguistics and a professor of psychology at Yale University, and is now a professor in the Department of Linguistics at the University of Southern California. He is a senior scientist at Haskins Laboratories in New Haven, Connecticut and a founding member of the Association for Laboratory Phonology.
He is best known for development, with Catherine Browman [3], of the theory of articulatory phonology, a gesture-based approach to phonological and phonetic structure. The theoretical approach is incorporated in a computational model [4] that generates speech from a gesturally-specified lexicon. Goldstein, Philip Rubin, and Mark Tiede [5] designed a revision of the articulatory synthesis model, known as CASY [6], the configurable articulatory synthesizer. This three-dimensional model of the vocal tract permits researchers to replicate MRI images of actual speakers and has been used to study the relation between speech production and perception.
