SACA : software assisted call analysis

30.000 advisory calls per year! How to analyze, rate and improve them interactively? For getting these goals a novel technique is introduced, which is based on a structure similar to a music score. Via a “duet”, guided by the advisor called, the main contents of the dialogue are extracted and stored automatically. At this, trained speech recognition is applied for the (known) advisor’s part for monitoring and controlling the call’s course, and keyword spotting is used for the (unknown) “customer” to pick out instances from sets of expected values. The results thereof fill an abstract score annotated to the call conducted. Then, because of the strong structure of such scores, the archive of all these dialogues is an ideal base for retrieval, exploration, comparison and clustering of calls, using e.g. graphical tools like knowCube®. -- Communication in healthcare ; telephony applications ; knowledge visualization ; speech recognition ; keyword spotting ; call analysis ; human computer interfaces ; retrieval ; exploration ; clustering ; multi criteria decision making ; knowledge management
