English speech timing : a domain and locus approach
This dissertation presents a descriptive framework for suprasyllabic processes in speech timing, and describes speech production experiments that investigate durational processes at the word level and the utterance level and the interaction of these processes with the effects of pitch accent. The experimental evidence suggests a model of a speech timing comprised of localised effects, in contrast with the diffuse processes typical of accounts that focus on the rhythmic organisation of speech. Within the descriptive framework, two types of process are associated with the domain, a familiar concept in prosodic phonology. Domain-edge processes lengthen segments near the initial and final boundaries of constituents: for example, word-initial lengthening and utterance-final lengthening. Domain-span processes are hypothesised to arise from an inverse relationship between the size of some constituent and the duration of some subconstituent: for example, word-spin compression (polysyllabic shortening) and utterance-span compression. The particular segments affected by each domain-edge or domain-span process are termed the âlocusâ; for example, the word is a domain of initial lengthening and the locus is the word-initial

English speech timing : a domain and locus approach. This dissertation presents a descriptive framework for suprasyllabic processes in speech timing, and describes speech production experiments that investigate durational processes at the word level and the utterance level and the interaction of these processes with the effects of pitch accent.
