Abstract:
A method of providing a caller with a directory assistance dialog, the dialog being switchable from an automated speech recognition (ASR) path to an operator-assisted (OP) path, comprising the steps of:receiving the call on the ASR path; prompting the caller for a city response; applying a speech recognition process to the city response; if the applying step fails, directing the remaining dialog to the OP path; if the applying step succeeds, directing the remaining dialog to a configuration switch; wherein the configuration switch is switchable to cause the remaining dialog to continue on the ASR path or to switch to the OP path, based on ASR success rates to the responses of the following prompt; such that after the step of applying a speech recognition process, and before any remaining ASR dialog, there are both a conditional decision based on the success or failure of the applying step, and the configuration switch that follows the conditional decision; if the configuration switch is set to the ASR path, performing the following steps: prompting the caller for a listing response; applying a speech recognition process to the caller's listing response; if the applying step fails, directing the remaining dialog to the OP path; if the applying step succeeds, performing a database search for the listing and giving out the listing to the caller upon completion of a successful search; if the configuration switch is set to the OP path, completing the dialog as an operator assisted call; and forwarding at least one response to a speech recognition tuning process.
