A method of analyzing speech application performance can include determining a call path for each of a plurality of calls from a log of an interactive voice response system having a speech application. Each call path can be defined by an ordered set of dialog nodes of the speech application. A number of occurrences of at least one selected type of event for the dialog nodes of the plurality of calls can be counted. At least one call path from the plurality of call paths can be indicated according, at least in part, to the number of occurrences of the selected type of event within the at least one indicated call path.
