Server Speech Command Reactivation via Word Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of home appliances face inconvenience when controlling them using speech recognition technology, as they need to repeatedly reactivate the speech command receiving function after each command, and there is no automatic reactivation mechanism.
Innovation Solution
A server system that automatically reactivates the speech command receiving function of home appliances by recognizing specific words in user speech input and transmitting response signals with control commands to maintain continuous functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition technology is used to control home appliances, then user convenience is improved, but the user must repeatedly reactivate the speech command receiving function after each command
Solution Approach 1:
The server performs preliminary analysis of the user's speech to determine if additional commands are likely to follow. Based on this preliminary assessment, the server proactively maintains the speech command receiving function active without requiring the user to reactivate it, thus preparing the system in advance for potential continued interaction.
Solution Approach 2:
The server analyzes the user's speech input and provides feedback by determining whether to maintain the speech command receiving function active. This feedback mechanism allows the system to adapt its operational state based on the characteristics of the user's input, creating a closed-loop control system that automatically adjusts to user needs.
2Productivity
If the speech command receiving function is terminated after each command, then system resource usage is reduced, but user interaction becomes inefficient
Solution Approach 1:
The speech command receiving function transitions from a static on/off state to a dynamic state that can be maintained active based on real-time analysis of user speech patterns. This dynamic adjustment allows the system to optimize between resource usage and interaction efficiency by adapting its operational state to the specific context of each user interaction.
3Speed
If the server maintains continuous speech listening, then response time is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous speech listening, the server implements periodic activation of the speech command receiving function based on analysis of user speech patterns. The function is maintained active during periods when additional commands are likely and deactivated when not needed, creating a periodic on/off pattern that balances response time requirements with energy conservation.

AI summary
The present disclosure relates to a server and a system including the same. The server according to an embodiment of the present disclosure includes: a communicator configured to perform communication through a network; a storage configured to store data on at least one predetermined word; and a controller configured to: upon receiving an input signal, including data on speech, from a first electronic device through the communicator, determine whether a last part of the speech corresponds to any one of the at least one predetermined word; in response to there being a word corresponding to the last part of the speech among the at least one predetermined word, transmit a first response signal, including data on a response to the speech and data on at least one additional query, to the first electronic device through the communicator; and in response to there being no word corresponding to the last part of the speech among the at least one predetermined word, transmit a second response signal, including data on a response to the speech, to the first electronic device through the communicator. Various other embodiments are also possible.
