1 Karen Wicklund: You mentioned at the very start of your talk that there were not a lot of studies done about the effects of hormones on the singing voice throughout the cycle. Indeed I’ve actually done 2 myself; one at Washington State University and one at Northwestern University. They’re reported in the May/June 1996 NATS Journal, (that’s the Northwestern Study), also the September 1998 Medical Problems of Performing Artists. Audio link.

2 John Nix: It seemed to me that the Yasmin®, by basically stabilizing the levels of estrogen and progesterone, the one variability then that you saw during the luteal phase when they were on that vs. the placebo, the follical stimulating hormone, FSH, would be the one thing that was not stabilized by using the Yasmin®; maybe that’s related to the changes you saw in closed quotient? Is that possible? Audio link.

3 Ron Scherer: Just a couple of quick things: Do you plan to actually do perceptual judgements of voice quality? [Lã: Yes I do] OK, so the term "voice quality" actually is appropriate here. Closed quotient, of course, is not a voice quality measure per se. You seem to be linking those. The other comment: were any of these females vocal fold tissues looked at? [Lã: no they were not] Their fundamental frequency, are you going to measure that? [Lã: yes it was]. A little swelling of the vocal folds would tend to increase the closed quotient ...listen to audio for further discussion. Audio link.
4 Theresa Brancaccio: Did you have the singers explore the extremes of their upper ranges? Because I know there is a concern that at the top, the very upper notes could be lost, and there is a concern about also darkening of the voice that would be permanent. Audio link.
