Metadata visualisation techniques for emotional speech corpora

Our research in emotional speech analysis has led to the construction of dedicated high quality, online corpora of natural emotional speech assets. Once obtained, the annotation and analysis of these assets was necessary in order to develop a database of both analysis data and metadata relating to each speech act. With annotation complete, the means by which this data may be presented to the user online for analysis, retrieval and organization is the current focus of our investigations. Building on an initial web interface developed in Ruby on Rails, we are now working towards a visually driven GUI built on Adobe Flex. This paper details our work towards this goal, defining the rationale behind development and also demonstrating work achieved to date.
