Fronting (phonology) in the context of "Germanic umlaut"

New Orleans English is American English native to the city of New Orleans and its metropolitan area. Native English speakers of the region actually speak a number of varieties, including the variety most recently brought in and spreading since the 20th century among white communities of the Southern United States in general (Southern U.S. English); the variety primarily spoken by black residents (African-American Vernacular English); the variety spoken by Cajuns in southern Louisiana (Cajun English); the variety traditionally spoken by affluent white residents of the city's Uptown and Garden District; and the variety traditionally spoken by lower middle- and working-class white residents of Eastern New Orleans, particularly the Ninth Ward (sometimes known, since at least the 1980s, as Yat). However, only the last two varieties are unique to New Orleans and are typically those referred to in the academic research as "New Orleans English". These two varieties specific to New Orleans likely developed around the turn of the nineteenth century and most noticeably combine speech features commonly associated with both New York City English and, to a lesser extent, Southern U.S. English. The noticeably New York-like characteristics include the NYC-like short-a split (so that mad and map, for example, do not have the same vowel), non-rhoticity, th-stopping (so that, for example, "those" may sound like "doze"), and the recently disappearing coil–curl merger. Noticeably Southern characteristics include the fronting of /oʊ/ and possible monophthongization of /aɪ/ (just these features, plus non-rhoticity, often characterize the Uptown accent).

Often, the term "Yat" refers particularly to the New Orleans accents that are "strongest" or most especially reminiscent of a working-class New York City accent, though others use the term as a regional marker, to define the speech heard in certain parts of the city and its inner suburbs. Used in these narrower senses, Yat is simply one of many sub-dialects of New Orleans. The word comes from the common use of the local greeting, "Where y'at?" or "Where are you at (i.e. in life)?", which is a way of asking, "How are you?"
