A method and apparatus are used for analyzing dialogs in an interactive natural language speech recognition system. As a telephone call is received in the interactive natural language speech recognition system, user utterances are digitized and stored. A data log is formed which stores the prompt played, the dialog state, the address location of the audio recording of the user's responses, the recognition grammar, the recognition result type, the recognized word string, the understood meaning/interpretation, and the recognition latency. The telephone call can be virtually reconstructed from the stored user utterances and the data log. An automatic data analysis tool provides information regarding the relative success and failure of the various dialogs as an aid to modifying the dialogs to improve system performance.

[ What is claimed is:] [8.]8. A method of designing dialogs for a natural language speech recognition system comprising the steps of:a. receiving one or more telephone calls, each telephone call having a plurality of dialogs, each dialog including a system generated utterance and a user response utterance;b. storing only each user response utterance forming a stored user utterance; andc. generating a data log for each dialog including an identifier for the system generated utterance and an indicator regarding success of the dialog.
