Video mail retrieval: the effect of word spotting accuracy on precision

The goal of the video mail retrieval project is to integrate state-of-the-art document retrieval methods with high accuracy word spotting to yield a robust and efficient retrieval system. This paper describes a preliminary study to determine the extent to which retrieval precision is affected by word spotting performance. It includes a description of the database design, the word spotting algorithm, and the information retrieval method used. Results are presented which show audio retrieval performance very close to that of text
