Abstract:
1. A method of identifying problems in a speech recognition application, the method comprising: obtaining from a computer storage medium a speech application call log containing log data on question-answer (QA) states and transitions; generating from the speech application call log, using a processor coupled to the computer storage medium, for each of a plurality of transitions between states in the speech application call log, a parameter which is indicative of a gain in a success rate of the speech recognition application if all calls passing through the transition passed instead through others of the plurality of transitions, wherein generating the parameter for each of the plurality of transitions comprises generating the parameter, for each of the plurality of transitions between the states, indicative of the gain in the success rate of the speech recognition application if all calls passing through the transition were instead evenly distributed between others of the plurality of transitions; ranking, using the processor, the plurality of transitions as a function of their corresponding generated parameters, indicative of a gain in the success rate of the speech recognition application if all calls passing through the transition passed instead through others of the plurality of transitions, to identify transitions which will most improve performance of the speech recognition application; and displaying on a display device the plurality of transitions ordered as a function of rank for use by a user in identifying problems in the speech recognition application in order to improve performance of the speech recognition application.
