|Regional Accent of humans map by William Labov|
One commonly-used field technique for bigfooting is call blasting. Back in the late 1990's and 2000's, this was usually done with loudspeakers and amplifiers hooked up to CD players. The most common calls used were the Tahoe Scream (there is no public source for this recording) and the Ohio Howl.
While John Frietas is often recognized as the godfather of call blasting, it was Roger Patterson himself that tried this method first to my knowledge. He not only recreated bigfoot sounds by yelling into church bells (to add resonance), but he also blasted calls off of a tower on a property in Tampico, WA.
Call blasting sounds purportedly made by bigfoots brings a number of questions with it. First of all, how does one know the sounds are bigfoot sounds unless somebody saw the creature make the noise? Even if the recordings are in fact bigfoot sounds, what are the bigfoots saying? After all, they could be saying, "Stay away! There's a human here!"
One interesting question that has arisen is if bigfoots have regional accents. Would a Southern bigfoot (possibly with a drawl?) answer or ignore one of its Yankee brethren? Would a Midwest bigfoot shun or welcome a Canadian sasquatch's greeting? I would hope that bigfoots would be above stereotyping based on accents...
I ran across this article that brings to light a precedence of regional accents in primates. Sure, these are gibbons and not bigfoots, but if one ape species has this characteristic, perhaps others do. After all, humans have accents...

Apes Found to Have Regional Accents
by Jake Richardson
A group of researchers has discovered that crested gibbon apes have regional accents. The scientists studied the singing of over 400 crested gibbons in 24 different locations in Asia.
The gibbons studied live in the rainforests of Vietnam, Cambodia, Laos and China. “Each gibbon has its own variable song but, much like people, there is a regional similarity between gibbons within the same location,” said lead researcher Van Ngoc Thinh. (Source: UPI.com) (Their study was published in the journal BMC Evolutionary Biology.)
Gibbon songs are made to travel over long distances in thickly vegetated areas by having a single frequency. It was found the songs that were most similar came from species that genetically were very closely related. Identifying gibbons by their songs is easier than by genetics because obtaining physical samples is difficult, whereas the songs are constantly being emitted and can be heard from some distance. Also, the songs can help identify where the gibbons are from, sort of like regional accents for humans.
