METHOD AND APPARATUS FOR PROVIDING SERVICES USING VOICE RECOGNITION IN POS SYSTEM
First Claim
1. A method of providing services using voice recognition in a Point Of Sales (POS) system, the method comprising the steps of:
- loading an execution command, set for each service subject that is provided by the POS system, for each group;
registering information on a voice pattern corresponding to the execution command for each item for each of the loaded groups with a voice recognition engine registration unit;
detecting operation mode of the POS system and activating a microphone by driving voice recognition mode in response to the detected operation mode;
converting a signal, received through the activated microphone, into digital data, detecting properties of a sound wave from the converted digital data, and extracting sound wave analysis data for authenticating the received signal from the detecting properties;
checking whether the extracted sound wave analysis data has been previously registered or not and assigning a service use right to the received signal according to a result of the check; and
performing voice recognition conversion on the received signal, searching for an execution command having a maximum likelihood for the resulting data, and performing one or more services corresponding to the retrieved execution command.

Abstract
A method of providing services using voice recognition in a POS system includes loading an execution command set for each service subject provided by the POS system for each group; registering item-based voice pattern information on the execution command for each group; detecting operation mode of the POS system and activating a microphone by driving voice recognition mode in response to the detected operation mode; converting the received signal of the activated microphone into digital data, detecting properties of a sound wave from the digital data, and extracting sound wave analysis data from the detecting properties; checking whether the sound wave analysis data has been registered and assigning a service use right to the received signal according to a result of the check; and performing voice recognition conversion on the received signal, searching for an execution command having a maximum likelihood for the resulting data, and performing services corresponding to the retrieved execution command.

8. An apparatus for providing services using voice recognition in a Point Of Sales (POS) system, the apparatus comprising:
-
a microphone; an Analog-to-Digital (A/D) converter unit configured to convert a signal, received from the microphone, into digital data; a voice recognition engine registration unit specialized to the POS system; a sound wave conversion unit configured to detect properties of a sound wave from the converted digital data and extract sound wave analysis data from the detected properties of the sound wave; and a control unit configured to detect operation mode of the POS system, activate the microphone by driving voice recognition mode in response to the detected operation mode, and perform control so that the A/D converter unit converts the signal, received through the activated microphone, into the digital data, the sound wave conversion unit detects the properties of the sound wave from the converted digital data and extracts the sound wave analysis data for authenticating the received signal from the detected properties of the sound wave, whether the extracted sound wave analysis data has been previously registered or not is checked, a service use right according to a result of the check is assigned to the received signal, and voice recognition conversion is performed on the received analog voice signal. - View Dependent Claims (9, 10, 11, 12)
