A Critical Review of State-Of-The-Art Technologies for Cross-Language Speech Retrieval

Recent developments in monolingual speech retrieval, automatic speech recognition and crosslanguage text retrieval suggest that crosslanguage speech retrieval deserves some enquiry. To direct work in this new area, it is important to appreciate the possibilities and limitations of the component technologies. This paper gives a critical review of the state-of-the-art of technologies for speech retrieval in cross-language environments and outlines some possible experimental paradigms. Introduction Rapid developments in computing technology are bringing about new areas of research. One new research area has been the integration of information retrieval and spoken language processing to allow monolingual speech retrieval. This paper presents a critical review of the possible extension of this existing work to cross-language speech retrieval environments where queries 1 in one language can be used to retrieve documents in one or more others. Since this is a new area of research, we cons..
