An Acoustical Analysis of Raven I. McDavid, Jr.'s, Pronunciation of Vowel Norms for the Linguistic Atlas of the United States and Canada

of American dialects as David Carlson, Allan Metcalf, and Bill Kretzschmar. Primarily, though, the seminar was outstanding because of Raven I. McDavid, Jr., whose extensive knowledge of dialectology was partially passed on to us seminar participants. In addition to attending seminar meetings where Professor McDavid discussed such matters as the history of linguistic atlas studies and the methodology for such studies, seminar participants were encouraged to engage in dialect research by using the field records for the Linguistic Atlas of the North-Central States (LANCS) project, which were then housed at the University of Chicago. We were also able to listen to taped interviews for some of the LANCS records, thereby gaining an understanding of the strengths and weaknesses of differing interview techniques; to examine some of the preliminary manuscript for a LANCS handbook, including sections concerning charting of atlas items, calibration of phonetic transcripts, and so on; and to acquire materials for our own use. It is this latter category that brings us to the subject of this article: Professor McDavid’s recording of vowel norms for the linguistic atlas phonetic alphabet. On 14 July 1961, McDavid made a recording at the University of New Brunswick, in Fredericton, of vowel norms of the linguistic atlas phonetic alphabet. Intended
