Effect of Duration, Intensity, and F0 Alternations on Rhythmic Grouping

Stress patterns in language play a large role in how we perceive speech. Stress is assigned on the basis of duration, intensity, and F0. This study investigated the role that duration, intensity, and F0 play in rhythmic grouping. Subjects were presented with sequences of alternating squarewave segments that were varied on one of the aforementioned dimensions. They were asked to indicate whether they heard a trochaic or iambic rhythmic pattern. Results indicate that duration-varying sequences are grouped iambically, whereas intensity- and F0-varying sequences are grouped trochaically. Results replicate and extend previous research and may suggest a need for a reformulation of the Iambic/Trochaic Law.
