Duration in speech from an articulatory-functional perspective（2.26）

Speech happens in time and duration is a critical aspect of timing in speech. There has been much research of various duration phenomena at different levels, yet there is a lack of a coherent account that that links them together. In this tutorial I explore duration from an articulatory-functional perspective that views speech as an information system that encodes multiple layers of communicative functions through an articulation process (Xu, 2009). From this perspective, duration is both intrinsic (Fowler, 1980), i.e., bound by articulatory constraints, and extrinsic (Turk & Shattuck-Hufnagel, 2020), i.e., functionally controlled to encode information.
