Roughly a thousand articles for each of English, German and Dutch are available, each totalling around 300 hours of speech (with smaller amounts in another 25 languages). This data has recently been made accessible by Köhn et al. who automatically aligned the audio recordings to their respective article texts using speech recognition technology. Using these alignments, we are able to relate what parts of the article are spoken at any moment in the recordings.
Graphical User Interface
The graphical user interface of our full application, including forward/backward jumps between articles (magenta), article search (cyan) and within-articl search (green), the responsive table of contents (blue), a responsive list of links in the surrounding of what is being read (red), some textual status information (yellow), sliders indicating the relative position in the article (brown), buttons for standard audio navigation (forward/backward/pause), for listening to the table of contents, and for voice-based interaction (purple), and finally buttons to navigate based on article structure: by chapter, paragraph, sentence, or jumping ahead/back by 10 seconds per click (black). In the experiments, only parts of the interface are available to the users.
