Dear Reg

I would be fascinated to see the spectra to which you are referring, if you would be kind enough to send them to me. The only spectra I have ever encountered with reduced alternate partials are those containing subharmonics, which is quite clearly a different situation from falsetto.

To what sort of asymmetry are you referring? Do you mean that the vocal fold edge is straight in one fold but not the other? That they are different lengths? Or contact depths? I have not before come across the concept of asymmetry as intrinsic to a register and would be very interested to read your sources.
Kind regards
Sally
