Item locator system utilizing item and location bar codes
First Claim
1. A method comprising:
- converting, by a voice recognition system, an acoustic signal, representing a request for location information associated with an item having an association with an aisle and a shelf, into a digital signal;
monitoring, by the voice recognition system, for a user-definable setting, wherein the user-definable setting comprises a trigger word transmitted to the voice recognition system;
determining, by the voice recognition system, one or more words included in the acoustic signal based at least in part on the digital signal and said monitoring; and
providing, by the voice recognition system, feedback to the request for location information based at least in part on the determined one or more words, wherein the feedback includes an aisle identifier that identifies the aisle and a shelf identifier that identifies the shelf.

Abstract
An item location system uses voice activation and responsiveness to identify location(s) of item(s) sought by a user. The system may include a continuous speech recognition digital signal processor, a programmable microprocessor interfaced therewith, voice input and user feedback mechanisms, including audio and/or video feedback. Some embodiments utilize audio feedback to the user. The system also includes sufficient software and equipment to create item-identification/corresponding location-identification data pairs by utilizing item identifying bar codes on the items and matching them to location identifying bar codes physically situated on the corresponding locations. The continuous speech recognition engine may utilize Hidden Markov Models to create real time continuous speech recognition and feedback.

7. A voice recognition system, comprising:
-
an audio controller configured to convert an acoustic signal into a digital signal, wherein the acoustic signal represents a request for location information associated with an item having an association with an aisle and a shelf; and a voice recognition unit coupled to the audio controller and configured to; monitor for a trigger word transmitted to the voice recognition system and, in response to receipt of the trigger word, determine one or more words included in the acoustic signal based on the digital signal; and provide feedback, via an input/output device, to the request for location information, wherein the feedback is provided based at least in part on the determined one or more words, and wherein the feedback includes an aisle identifier that identifies the aisle and a shelf identifier that identifies the shelf. - View Dependent Claims (8, 9, 10, 11)
