Scholars say, yes, there is an American Jewish accent, but it's complicated. “Intonation has kind of been the red-headed stepchild of linguistics, where for a lot of time there was debate about whether or not it's really part of the linguistic system, or whether it was something else overriding it, essentially,” says Burdin. It’s only been about 15 years since linguists—just a few of them, really—have begun systematically attempting to study the rhythm, timbre, intonations, stresses, and pauses of speech, and the study is still in its infancy. It is particularly murky territory in English, where melody is not as important as it is in other languages. But there are some groups whose speech, long having been described as sing-songy, is suddenly of interest to researchers breaking new ground in the study of prosody. Appalachian English is one of those. And Jewish English is another.
