In 1958, Fry published a very influential paper detailing the interaction between F0, duration, and intensity in the perception of lexical stress. His main finding was that that hearers of American English rely more on F0 than on the other correlates in the perception of lexical stress. He ranked these three correlates as follows: F0 > Duration > Intensity. However, subsequent research by other phoneticians has yielded a variety of rankings: F0 > Intensity > Duration, Duration > Intensity > F0, Intensity > F0 > Duration, Intensity > Duration > F0, etc. The goal of this paper is to investigate how speakers of Central Minnesota English encode and rank the three acoustic correlates of stress. Ten speakers (five female and five male) produced a total of 1080 tokens (18 words x 2 syllables x 10 participants x 3 correlates). Our findings indicate that the gender of the speaker plays a more prominent role in the production of lexical stress than previously expected.
