Forgive me smiling upon you being able expressing your own dislike in a private correspondence to you and even mixing up Christian, a very reputated expert in psychology, with me. Admittedly, I am having problems in understanding your comment. Concerning Titze's model, I refer to Martin's paper, p. 87. Do you have any objection against the physical effect of trachea resonance on f0? Perhaps not. I understood that you consider this effect unlikely to be applicable to musical pitch in speech. Of course, f0 is not identical with pitch. I do not have much knowledge of the various methods for pitch tracking. Merely discrete samples of f0 can be exactly determined by measuring the distances between subsequent glottal pulses. See for instance my adress A015 (Don George). In that context, it does not matter whether f0 belongs to speech or musics. If my interpretation of Martin's data is correct, then they actually relate to f0 rather than to pitch. You are correct. A listener would probably not be able to perceive the pitch as exactly as we can measure the distance between two glottal pulses. I see this one more argument against Martin's original idea. I am not a proponent of that.
