The goal of my dissertation research is to investigate the combination of new ev- idence sources for improving informa- tion retrieval on speech collections. The utility of these evidence sources is ex- pected to vary depending on how well they are matched to a collection’s domain. I outline several new evidence sources for speech retrieval, situate them in the con- text of this domain dependency, and de- tail several methods for their combination with speech recognition output. Secondly, I highlight completed and proposed work for the production of this evidence.
