Television Voice Command Control by Operation State Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic equipment, such as television receivers, often fail to perform suitable control when the same command is input in different operation states due to reliance on past command execution history, leading to inadequate control responses.
Innovation Solution
Incorporating a system with a command information storage section, speech information obtainment section, command information extraction section, judgment section, control section, and command information registration section to perform speech recognition and adapt control based on the current operation state, allowing for customized command information registration and execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control is based on past command execution history, then the apparatus can respond to user intentions without concrete object commands, but it cannot execute suitable control when the same command is input in different operation states
Solution Approach 1:
The patent applies dynamics by making the command interpretation adaptive to the current operation state. The speech recognition result is dynamically adjusted based on the present state of the equipment rather than relying on static historical patterns. This allows the same command to have different meanings depending on the current state, resolving the contradiction between ease of operation and control accuracy.
Solution Approach 2:
The patent changes the parameter of command interpretation from fixed (based on history) to variable (based on current operation state). By introducing state-dependent parameter adjustment, the system can accurately interpret commands in different contexts while maintaining simple user input, thus resolving the contradiction between operational convenience and control reliability.
2Reliability
If multiple command information are stored for different operation states, then suitable control can be performed for each state, but the device complexity increases
Solution Approach 1:
The patent applies universality by creating a unified command information storage structure that serves multiple operation states. Instead of separate storage systems for each state, a single storage structure holds state-associated command information that can be selectively accessed. This multi-functional approach maintains control accuracy across different states while avoiding the complexity of multiple independent storage systems.
Solution Approach 2:
The patent introduces an intermediary mechanism (the state association structure) that links operation states with command information. This intermediary layer manages the relationship between states and commands, allowing the system to handle multiple states without requiring complex separate storage systems, thus resolving the contradiction between reliability and device complexity.
3Ease of operation
If speech recognition is used for control, then natural colloquialisms can be recognized, but the apparatus cannot distinguish the same speech input in different operation contexts
Solution Approach 1:
The patent applies preliminary action by pre-associating command information with specific operation states in the storage structure. Before speech recognition occurs, the system has already prepared state-specific command interpretations. This preliminary preparation enables accurate speech interpretation in different contexts while maintaining natural speech input, resolving the contradiction between ease of operation and measurement precision.
Solution Approach 2:
The patent implements feedback by using the current operation state as contextual information that refines speech recognition results. The system feedbacks the state context to the command interpretation process, allowing natural speech to be accurately distinguished in different operation contexts. This feedback mechanism resolves the contradiction between speech naturalness and interpretation accuracy.
