There is simply not enough evidence to suggest your theory that cooked meat lead to small jaws. Why? Because there was probably a reduction in robusticity before the event of fire (if we assume that erectus had fire, and not habilis.) Homo erectus started out scavenging, and over the course of its extremely long duration, probably moved onto cooked meat -- and there wasn't a significant change in the construction of their mandibles, teeth, zygomatic arches or maxilla to suggest that cooked meat might have lead to more gracile jaws. After erectus, of course, you have Homo sapiens, who is significantly more gracile. (I'm not counting neaderthalensis, because they were a side branch, and their jaws were cold adapted rather than dietary adapted.) Now, I'm not leaving meat out of the picture completely. I do believe that a higher content of meat lead to more gracile creatures (Aiello & Wheeler "Big Brains, Small guts"), but I don't think the state of the meat was the factor... just the increased quantity.

Regarding erectus, it is contentious, because they DID have significant development in their Brock's & Wernicke's regions, BUT up until recently it was thought that the larynx and pharynx of erectus probably hadn't dropped low enough to enable speech. But then that guy that claimed that neanders didn't have the dropped larynx was pretty much debunked fairly recently because his diagrams failed to take into consideration the different shape of the neander skull as compared to sapiens, ie lower and flatter, and more elongated horizontally, and this has also been applied to erectus, who also didn't have the vertically elongated skull that sapiens has. However, spinal evidence of erectus suggests that speech - as in symbolism and complexity - was probably not likely. (The idea being that more complex species have larger spinal cords, and erectus' was still the size of an ape.)
