Measurements were made for minimal glottal diameters from d\u2009=\u20090.005\u20130.32\u2009cm with a range of transglottal pressures of interest for phonation. Entrance loss coefficients were calculated at the glottal entrance for each minimal diameter and transglottal pressure to measure how far the flows in this region deviate from Bernoulli flow. Exit coefficients were also calculated to determine the presence and magnitude of pressure recovery near the glottal exit. The entrance loss coefficients for the three convergent angles vary from values near 2.3\u20133.4 for d\u2009=\u20090.005\u2009cm to values near 0.6 for d\u2009=\u20090.32\u2009cm. These coefficients extend the tables of entrance loss and exit coefficients obtained for the uniform glottis according to Fulcher, Scherer, and Powell [J. Acoust. Soc.
