Context-Aware Voice Recognition for Display Ambiguity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice recognition systems in display apparatuses often perform unintended operations due to ambiguity in user voice commands, leading to user inconvenience when multiple functions are associated with a single voice input.
Innovation Solution
A control method and system that determines the intended operation by analyzing the current usage status and function of the display apparatus, using voice recognition to match the user's voice command with the most relevant operation or service, and displaying a selection window for user confirmation or performing the operation based on stored commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is used to control display apparatus functions, then ease of operation is improved, but reliability deteriorates due to unintended operations from ambiguous voice commands
Solution Approach 1:
The system changes the parameter of voice command interpretation by incorporating contextual information (current usage status and active functions) into the recognition process. This allows the same voice command to have different meanings based on context, resolving ambiguity while maintaining ease of use
Solution Approach 2:
The system provides feedback to the user by displaying a selection window when a voice command is ambiguous. This feedback mechanism allows the user to confirm or correct the intended operation, ensuring reliability while preserving the convenience of voice control
2Adaptability or versatility
If multiple functions are associated with a single voice command, then adaptability is improved, but reliability deteriorates due to function selection ambiguity
Solution Approach 1:
The system dynamically changes the interpretation parameter of voice commands based on the current usage status and active functions. This allows one voice command to adaptively map to different functions depending on context, maintaining versatility while preventing erroneous execution through contextual disambiguation

AI summary
Apparatuses and methods related to a voice recognition system, a voice recognition server and a control method of a display apparatus, are provided. More particularly, apparatuses and methods relate to a voice recognition system which performs a voice recognition function by using at least one of a current usage status with respect to the display apparatus and a function that is currently performed by the display apparatus. A voice recognition system includes: a voice receiver which receives a voice command; and a controller which determines at least one from among a current usage status with respect to a display apparatus and a function currently performed by the display apparatus, determines an operation corresponding to the received voice command by using at least one from among the determined current usage status and the function currently performed by the display apparatus, and performs the determined operation.
