audio-based methods for navigating and browsing educational multimedia documents
We present several approaches to audio-centered browsing and navigation of multimedia documents in educational contexts. Such methods are required when the purely visual information is not sufficient to locate parts of interest within a document because the dominant information is contained in the audio stream, as is often the case in recorded talks or presentations. Reference implementations as well as an integration of selected approaches in a state-of-the-art lecture player are demonstrated.
