Abstract
A point-of-sale terminal initiates a transaction and provides a prompt to be spoken to an operator (e.g. a cashier) of the POS terminal. The prompt indicates a verbal message that is to be spoken by the operator. The POS terminal then receives an audio signal via a microphone or similar device to record what the operator has spoken. Using speech recognition, the POS terminal determines whether the audio signal corresponds to the prompt, and thus whether the operator spoke the prompt properly. In one embodiment, the transaction is paused until the operator properly speaks the prompt. In another embodiment, the POS terminal stores an indication of whether the operator has properly spoken the prompt, thereby allowing the performance of the operator to be measured.
