Abstract
We present an approach to the definition and application of confidence measures to the speech understanding module in a spoken dialog system, which answers queries about railway timetables and prices by telephone in Spanish. Some experiments have been carried out, and the results in terms of understanding accuracy depending on the threshold of confidence considered, are presented.
Work partially funded by CICYT under project TIC2002-04103-C03-03, Spain.
