An Extended Imprecise Computation Model for Time-constrained Speech Processing and Generation

We describe a real-time speech application which simulates the human production of natural-language utterances in a two-person conversation. Since generating such utterances is a complex and often time-consuming task, we examine the timing constraints and result-quality requirements of this application, as well as the dependencies between the timing constraints and result qualities of the tasks that generate utterances. We then extend the imprecise computation model to capture these dependencies and discuss the general applicability of the extended model.
