"... there is evidence from combined acoustic and cineradiographic research
that slight and heavy nasality is correlated with velic adjustments
producing different cross-sectional areas of the velopharyngeal opening
into the nasal cavity. Bjork (1961) showed that slight nasality correlated
with a cross-sectional area of about 60 square millimeters, compared with
areas of some 250 square millimeters for heavy nasality."
Bjork (1961) is L. Bjork, (note that should be o-umlaut), 'Velopharyngeal
function in connected speech. Studies using tomography and cineradiography
synchronized with speech spectrography.' Acta Radiologica (Stockholm),
supplement no. 202.
