Abstract:Current technology allows us to record and store multimodal recordings of meetings. These recordings can function like an archive, as a replacement for minutes. Although recording these meetings is straightforward, finding specific information in them is not. In order to make it easier to find information in meeting recordings, meeting browsers are developed. A meeting browser may consist of many different components, each making it possible to browse or search the recorded media in a different manner. Meeting recordings consist of video and audio recordings. Other modalities, such as speech ecognition transcripts and speech segmentations can be extracted from these sources and used to make browsing and searching the meeting more efficient in the sense that information can be found easier and quicker. This report describes two novel approaches for presenting recorded meeting audio in an interactive meeting browser: time-compressed audio and simultaneous playback using binaural audio. Both methods reduce the playback time of the audio without discarding any of the spoken content from the audio, resulting in the same information intake in less time. User tests were carried out to see which approach yields a better performance.
