Goal
The project was to extract pilot-flight controller dialogs from air traffic control recordings. I worked on the dialog identification code which used unsupervised agglomerative clustering based on cepstral features to identify the separate controller and pilot conversations. The 1st step was to separate the pilots from the controllers which was easy due to pilots have more background noise. Then we did cuts lower in the dendrogram to pull out the separate pilots in the pilot side of the tree and controllers from the controller side of the tree. I wrote an algorithm to then intersect the controller clusters with the pilot cluster to form dialogs. I also wrote the user interface to the overall system on a Symbolics Lisp Machine and used Ken Anderson's outstanding Grapher package to generate the many graphs and graphical drill downs in the interface.
