Problems solved by technology

[0003] However, in a typical home environment with more than one television, if the app only recognizes that the user said "Turn on TV" to the mobile phone, then without appropriate location information about where the voice command was spoken, a decision should be made. Which TV to turn on is ambiguous

Embodiment Construction

[0014] In the following description, various aspects of embodiments of the invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding. It will also be apparent, however, to one skilled in the art that the present invention may be practiced without the specific details presented herein.

[0015] figure 1 A situation is shown where more than one television set 111 , 113 , 115 , 117 is present in different rooms 103 , 105 , 107 , 109 in the home environment 101 . In the home environment 101, if the user 119 simply instructs the mobile phone 121 to "turn on the TV", it would be impossible for a voice command system based personal assistant application on the mobile phone to determine which TV needs to be controlled.

[0016] To solve this problem, the present invention considers the surrounding acoustics when the user indicates the voice command of "turn on the TV", and applies the exis...

Description

technical field [0001] The present invention relates to a method and system for identifying a location associated with a voice command in a domestic environment to control a household appliance. More particularly, the present invention relates to a method and system for using a machine learning method to recognize where a user issues a voice command and then perform an action of the voice command on a home appliance in the same room as the user. Background technique [0002] Personal assistant applications via voice commands on mobile phones are becoming more and more popular today. This type of application uses natural language processing to answer questions, make suggestions, and perform actions on home appliances such as televisions by delegating requests to destination televisions or STBs (Set Top Boxes). [0003] However, in a typical home environment with more than one television, if the app only recognizes that the user said "Turn on TV" to the mobile phone, then wit...
