Related work in conversational awareness is found in [2]. Here, a system tracks the topic using a speech recognizer to automatically change slides in a power-point presentation. Techniques for topic-spotting arise in the text classification community which uses typed (vs. speech recognized) words to classify Reuters documents, etc. [4]. Wearable audio systems can also track the audio context [1] at a coarser level by analyzing the raw signals instead of words. Finally, wearable keyboard based systems track typed words in real-time to pull up relevant reference documents automatically [5]. Such systems have a coarse understanding of the conversational or textual context and this permits an intelligent output that is relevant to the situation.
