  Spontaneous speech in the form of conversations, meetings, voice-mail,
interviews, oral history, etc. is one of the most ubiquitous forms of human
communication. Search engines providing access to such speech collections have
the potential to better inform intelligence and make relevant data over vast
audio/video archives available to users. This project presents a search user
interface design supporting search tasks over a speech collection consisting of
an historical archive with nearly 52,000 audiovisual testimonies of survivors
and witnesses of the Holocaust and other genocides. The design incorporates
faceted search, along with other UI elements like highlighted search items,
tags, snippets, etc., to promote discovery and exploratory search. Two
different designs have been created to support both manual and automated
transcripts. Evaluation was performed using human subjects to measure accuracy
in retrieving results, understanding user-perspective on the design elements,
and ease of parsing information.
