Video Mail Retrieval Using Voice: An Overview of the Stage 2 System

MIRO '95 - G.J.F. Jones, J.T. Foote, K.S. Jones & S.J. Young - This paper outlines the Video Mail Retrieval (VMR) project at Cambridge University. - The goal of the VMR project is to develop an application for the retrieval of spoken documents in multimedia systems. - Speech documents pose a particular problem for retrieval since the contents are unknown. - The VMR project seeks to address this problem by combining state-of-the-art speech recognition with established document retrieval technologies to provide an effective and efficient retrieval tool. - Experimental results with a small spoken message collection show that retrieval precision is somewhat dependent on the generality of the acoustic modelling used. - For talker-dependent acoustic modelling retrieval performance is around 95% of that observed when text transcriptions of the same files are used. - However, even with incorporation of completely open-user talker-independent acoustic models, retrieval performance of about 75% of text can be obtained. - Our website uses cookies to help improve your experience.
