1. A method of facilitating a dialog for a caller, the dialog being switchable from an automated speech recognition (ASR) path to an operator-assisted (OP) path, the method comprising: providing a series of ASR sub-dialogs, each sub-dialog including a prompt requesting information from the caller and a response from the caller; performing an ASR analysis of each received response, wherein each ASR analysis indicates whether the applicable ASR sub-dialog was successful or unsuccessful; after an unsuccessful ASR sub-dialog, branching the dialog to the OP path; providing a series of configuration switches, each configuration switch being located after a respective ASR sub-dialog, wherein a configuration switch can be set to branch unconditionally the dialog to the OP path even if the ASR analysis from the respective ASR sub-dialog is successful; setting an identified configuration switch to branch unconditionally to the OP path based, at least in part, on a success rate of an ASR sub-dialog that follows the identified configuration switch; forwarding responses from a selected ASR sub-dialog to a speech recognition tuning process; and tuning an ASR analysis of the selected ASR sub-dialog based at least on the forwarded responses.
