Vocal Access to a Newspaper Archive: Assessing the Limitations of Current Voice Information Access Technology

摘要

This paper presents the design and the current prototype implementation of an interactive vocal Information Retrieval system that can be used to access articles of a large newspaper archive using a telephone. The implementation of the system highlights the limitations of current voice information retrieval technology, in particular of speech recognition and synthesis. We present our evaluation of these limitations and address the feasibility of intelligent interactive vocal information access systems.
