Focus of Attention in the Hearsay-II Speech Understanding System
Using the concepts of stimulus and response frames of scheduled Knowledge source instantiations, competi t ion among a l ternat ive responses, goals, and the desirabi l i ty of a knowledge source instantiat ion, a general attentional contro l mechanism is developed. This general focusing mechanism faci l i tates the experimental evaluation of a var iety of specific at tent ional control policie...

متن کاملThe Hearsay Speech Understanding System: An Example of the Recognition Process
This paper describes the structure and operation of the Hearsay speech understanding system by the use of a specific example illustrating the various stages of recognition. The system consists of a set of cooperating independent processes, each representing a source of Knowledge. The knowledge is used either to predict what may appear in a given context or to verify hypotheses resulting from a ...
متن کاملIntegrating multiple knowledge sources for improved speech understanding
In spoken dialog systems it is often the case that the sentence produced by the decoder with the highest recognition probability may not be the best choice for extracting the intended concepts. Lower ranking hypotheses may present better alternatives. In this paper, we show how to integrate multiple knowledge sources for the decision of selecting one of these hypotheses. A scoring schema combin...
متن کاملA Knowledge - based System Integrating Speech and Image Understanding – Manual Version 1 . 0 –
We present a system that integrates speech and image understanding in the domain of a construction task. Knowledge needed to interpret speech and images is stored in one homogeneous knowledge base using the semantic network formalism ERNEST. It provides a means for constraint propagation and therefore – using a uniform representation of the information gained from real input data – the speech a...
