Sociophonetic vowel analysis relies heavily on measurements of resonant frequencies, particularly of the first and second formants. Automated formant estimation using linear predictive coding (LPC) algorithms in software like Praat greatly increases efficiency compared to hand measurements and allows researchers to analyze more data than was possible before this technological advancement. However, many authors have noted LPC analysis is prone to certain types of errors (e.g., Di Paolo, Yaeger-Dror, & Wassink, 2011; Harrison, 2013; Labov, Ash, & Boberg, 2006; Strelluf, 2019; Styler, 2017). In one common error, which I call “faulty low F2” (FLF2), LPC identifies a spectral peak between …

Vowel Pronunciation As An Ethnic Marker: Pacific Islander Teens In Utah, Lisa M. Johnson

Despite the growing numbers and visibility of Native Hawaiians and other Pacific Islanders (NHPIs) in the U.S., these Americans are generally overlooked in the research on language variation. American dialectology tends to focus on speakers of European descent, and most research on minority ethno-racial groups has concentrated on larger demographic groups, such as African American and Latinx American groups. This combination of research deficits limits our understanding of linguistic variation and the social forces that influence it. In addition, it may reinforce stereotypes of “ethnolects” as nonstandard and wholly separate from regional and stylistic influence. (See Eckert, 2008.) Many of …
