134821

As showed in the table above, the corpus size of the demo package here is about 21 hours recording and 134821 tokens (words) in total. On average, the recording duration of each of the 31 transcripts/lessons is about 42 minutes; and the word count of each of the 31 transcripts/lessons is about 4400 tokens (words).

If you want to play the audio clips and video clips of your search results, you must check the option "Show results in turns" in the lower left corner of the query window when submitting your queries. Please be reminded that there are a few misalignments of audio clips due to the resampling of audio files. We are currently fixing this problem. For testing purpose, you can only play some of the audio/video clips of the search results in the result list. The audio icon and video icon displayed in your query result indicate the availability of the media.

For a better performance with audio and video played in your browser, we recommend the latest version of Internet Explorer. If you do want to use Mozilla Firefox, some media files may not be played automatically, as Firefox has limited capacity to play Windows Media files, and you may require changes to your system configuration. We recommend your IT administrator assist in correcting the problem (the proper Windows Media and Active X plugins need to be installed). Go to: http://forums.mozillazine.org/viewtopic.php?t=206213 and follow the steps exactly. After doing so, you should be able to view the Windows Media files via Firefox Browser.

3. Speaker Index in the Transcripts

We have created a scheme to index the speakers in the transcripts. In this way, the corpus process and database query can be easier, and it can also help us to generate the speaker's profile across levels, streams, subjects, etc. in corpus query. In addition, this index can also enhance the anonymity of speakers when the corpus data is released to the public. Here is the list of speakers you can find in the transcripts:
