|Abstract: ||Recently, automated process for classroom teaching and learning has become one of
the main interested areas in multimedia authoring activities. One such application is
the distance learning which aims to provide a quality assurance learning environment
for teaching and training remotely.
In this project, I study the synchronization of lecture slides with the audio clips which
are captured from recent lectures. At the beginning, speech recognition is performed
for the detection of phonemes in the audio clips. After that, phoneme sequence
detection techniques are used to facilitate the detection of words in audio files. Finally,
the Earth Mover's Distance (EMD) algorithm is modified for the matching of slots
The results of this project give an evaluation on the performance of different parts.
These include the evaluation on the correctness and accuracy of speech recognition,
and the performance of the new modified EMD algorithm. Finally, we estimate the
performance of the whole project after different parts are combined. The real situation
is also simulated to give a completed evaluation of this project.|
