A note about the movie: This clip, and other clips
elsewhere on this site, are taken from a high speed x-ray movie of
Kenneth N. Stevens. The original 35 mm cineradiography film was made
by Sven Öhman and Kenneth Stevens at the Wenner-Gren Research
Laboratory at Norrtull’s Hospital, Stockholm, Sweden, as described in
an abstract of a paper by S. E. G. Öhman and K. N. Stevens
“Cineradiographic studies of speech: procedures and objectives.”
J. Acoust. Soc. Amer. 35, 1889 (1963), and in K. N. Stevens and
S. E. G. Öhman “Cineradiographic studies of speech.” Quarterly
Progress and Status Report, Speech Transmission Laboratory, KTH,
Stockholm, 2/63, 9-11 (1963). The film was converted to DVD format and
distributed at a conference at MIT in June 2004, honoring Professor
Stevens, From Sound To Sense: 50+ Years of Discoveries in Speech
Communication. The film was part of the poster Articulatory
KENematics: Revisiting the Stevens cineradiography, K.G. Munhall
(Queen's University), M. Tiede (Haskins Laboratories), J. Perkell
(Massachusetts Institute of Technology), A. Doucette (Industrial Light
& Magic), & E. Vatikiotis-Bateson (University of British
Columbia). The original film was described and analyzed in detail by
Joseph S. Perkell in Physiology of speech production: Results and
implications of a quantitative cineradiographic study.Cambridge, Mass:
M.I.T. Press (1969).
