This chapter summarizes the basic mechanisms of the Articulatory Phonology model, currently the most thoroughly worked-out model in the literature, with a focus on its system-intrinsic mechanisms used to account for systematic variation in speech timing. Key features of the model are reviewed, and oscillator-based mechanisms are described for timing control for articulatory gestures, control of inter-gestural coordination, prosodic timing control, and the control of overall speech rate. Strengths of the AP/TD approach are discussed, which include facts that are well-accounted-for within this model, such as the predominance of CV syllables within the world’s languages, as well as characteristics of processing within the model that are assumed to be advantageous, such as the avoidance of the need to explicitly plan the details of articulatory movement when planning an utterance. This presentation forms the basis of the evaluation presented in subsequent chapters. |
