Reg,
While reading what you wrote about "cord contact" and asymmetry, I was wondering whether there was a mode in which the vocal folds would never be really open : they would only let small puffs, "bubbles" of air make their air between them, but either the bottom or the top part of the folds would always be adducted. When one looks at drawings trying to represent the "heavy" mechanism, one can conclude that the closed phase is longer than the open one and that there would be little change to introduce to the system for the open phase never to occur... Thanks for clarifying this point!
