19. The computer usable storage device of claim 17 , wherein the computer usable program code further causes the computer hardware system to perform grouping calls having matching call paths.
17. A computer usable storage device having stored therein a computer usable program code for analyzing speech application performance, the computer usable program code, which when executed by a computer hardware system, causes the computer hardware system to perform: determining a call path for each of a plurality of calls from a log of an interactive voice response system comprising a speech application, wherein each call path is defined by an ordered set of dialog nodes of the speech application; determining a number of occurrences of at least one selected type of event for the dialog nodes of the plurality of call paths; and indicating at least one call path from the plurality of call paths according, at least in part, to the number of occurrences of the selected type of event within the at least one indicated call path, wherein the computer usable storage device is not a transitory, propagating signal per se.
