Item Communicative Alignment of Synthetic Speech(2011-06-20T09:36:36Z) Bachan, Jolanta; Demenko, Grażyna. PromotorThe central claim of the thesis is that a dialogue system should be well-motivated by dialogue theory and by analysis of actual dialogues, and that the resulting system should be tested in a real-world scenario. The thesis concentrates on methodology and investigates a range of methods from discourse theory through corpus linguistic studies to automata theory in order to fulfil this requirement. The operational aim is to provide a basic proof-of-concept dialogue system based on the claim and combining written and spoken communication. The operational aim is therefore not to develop a fully functional engineering standard dialogue system, but a prototype which demonstrates the methodology of the thesis and fulfilment of the main claim in a simulated but realistic stressful scenario. An emergency scenario and a map-task dialogue were chosen as an example and alignment of semantic representations of the map was claimed to be essential for successful communication. Linguistic specifications were outlined and their implications for the spoken dialogue system development were discussed. A prototype dialogue system using these specifications was developed and successfully evaluated with human users. The prototype system combines text input with speech output, with a dialogue engine based on two linked finite state automata: one for the dialogue manager and one for map traversal.
