Voice Control Token Synchronization in Building Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice control systems in building automation require additional satellite speech recognition devices across multiple rooms, which are not future-proof due to the lack of a method for resynchronizing voice tokens with the latest command set, limiting the expansion of voice command vocabulary.
Innovation Solution
Implementing a system where satellite speech recognition units transmit voice command tokens back to a central controller, which periodically updates these tokens to synchronize with the latest command set, ensuring compatibility and expanding the voice command vocabulary over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If satellite speech recognition devices are installed in different rooms to expand voice range, then voice control coverage is improved, but device complexity and system synchronization difficulty increase
Solution Approach 1:
The system divides the building into multiple zones with satellite speech recognition devices distributed in different rooms, each independently capturing voice commands locally while maintaining connection to the central controller through wireless communication
Solution Approach 2:
The central controller periodically transmits updated voice command tokens to all satellite devices at scheduled intervals, ensuring all devices synchronize their command vocabularies without requiring continuous communication or manual intervention
2Use of energy by moving object
If voice tokens are embedded in battery-operated wireless sensors to reduce power consumption, then energy efficiency is improved, but adaptability to future command updates deteriorates
Solution Approach 1:
The system transitions from static embedded voice tokens to dynamic updateable tokens, where the central controller can periodically push new voice command vocabulary to satellite devices, allowing the system to adapt to expanding command sets while devices remain in low-power mode between updates
Solution Approach 2:
The system implements a feedback mechanism where satellite devices receive periodic token updates from the central controller, ensuring they maintain synchronization with the latest voice command vocabulary without requiring continuous power or manual intervention
3Reliability
If a central controller periodically updates voice command tokens to satellite units, then system synchronization and future-proofing are improved, but communication overhead and energy consumption increase
Solution Approach 1:
The central controller implements periodic token updates at optimized intervals, transmitting new voice command vocabulary only when changes are available, thereby maintaining synchronization reliability while minimizing unnecessary communication events that would consume energy
Solution Approach 2:
The system maintains continuous synchronization capability through periodic updates, ensuring voice tokens remain current without requiring constant communication, thus balancing reliability with energy efficiency by updating only when necessary

AI summary
A regional monitoring system can include a plurality of voice sensing units each of which incorporates speech recognition circuitry. In response to recognizing a verbal command at a unit, a coded representation, or token, along with location information, can be transmitted to a system control apparatus. Upon receipt of the token, the control apparatus can carry out the requested command or provide requested information.
