The pitch session on Friday gave us a chance to tell our lecturer and peers about our projects, and what research we had conducted thus far. During my project research presentation it became apparent that my biologically focused findings might not be immediately relevant to the production requirements of the project as I had mainly discussed my findings on the descended and mobile larynx found in mammals along with the concepts of vocal learning (which would bear no relation to production requirements.)
A suggestion included investigating subtractive synthesis and if possible as an outcome for my project; the creation of a soft/hardware sound effects chain for a tiger emulation system for a human voice. Upon reflecting on this point, I created a very simplified IO diagram;
HUMAN VOICE >>> PROCESS >>> MODIFIED VOICE (Tiger, Etc.)
This "Process" will be what the project will manifest itself with the experimental production/synthesis techniques, along with the informative biology sources.
Preceding this, I also found the full video of the Big Cats episode of Inside Natures Giants that showed the lions mobile and sizable larynx;

This documentary features an interesting experiment in which Tecumseh Fitch attached a tube to the lions larynx and blew compressed air through it. He then repeated this and pulled the larynx back which change the pitch of the roar, essentially a biological pitch shifter.
