Display Device Speech Recognition Sensitivity Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in user satisfaction due to varying speech recognition performance, as some users may not recognize the starting word despite uttering it, while others may have the speech recognition activated incorrectly, leading to disturbed content appreciation.
Innovation Solution
A display device that allows users to adjust the recognition sensitivity of the speech recognition starting word by determining a valid recognition threshold range, assigning thresholds to sensitivity levels, and providing a sensitivity setting interface for user input, enabling personalized recognition settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the recognition threshold is set to be sensitive, then the starting word is more likely to be recognized, but false recognition increases when the starting word is not uttered
Solution Approach 1:
The patent applies parameter changes by adjusting the recognition threshold parameter to different sensitivity levels. The threshold is modified within a valid range to balance between recognizing actual starting words and avoiding false recognition, allowing the system to adapt to different user needs and voice characteristics without changing the underlying recognition engine.
2Reliability
If the recognition threshold is set to be strict, then false recognition is reduced, but the starting word may not be recognized when uttered
Solution Approach 1:
The patent resolves this contradiction by providing adjustable threshold parameters that can be modified within a valid recognition range. This allows the system to loosen the threshold strictness when needed to improve starting word detection while maintaining controls against excessive false recognition, adapting to different operating conditions and user requirements.
3Ease of operation
If a fixed recognition threshold is used, then the system is simple to operate, but it cannot satisfy users with different voice characteristics and recognition preferences
Solution Approach 1:
The patent transforms the static fixed threshold into a dynamic adjustable parameter. The recognition threshold can be modified within a valid range to adapt to different users' voice characteristics and preferences. This dynamic adjustment capability allows the system to maintain simplicity while providing customization options for improved user satisfaction and recognition performance.
4Adaptability or versatility
If the recognition sensitivity is adjustable, then user satisfaction is improved, but the device complexity increases
Solution Approach 1:
The patent manages complexity by implementing parameter adjustment within a constrained valid recognition threshold range. Rather than allowing arbitrary changes to multiple parameters, the system provides controlled adjustment of the recognition threshold parameter, balancing user customization needs with system simplicity. The adjustment is guided by pre-determined valid ranges that prevent excessive complexity.

AI summary
An embodiment of the present disclosure provides a display device for adjusting recognition sensitivity of a speech recognition starting word, the display device including a display, a microphone, a memory configured to store a default starting word recognition engine that recognizes a speech recognition starting word, and a processor configured to determine a valid recognition threshold range of the default starting word recognition engine, assign recognition thresholds within the valid recognition threshold range to a predetermined number of sensitivity levels, display a sensitivity setting interface including the sensitivity levels through the display, and set a default recognition threshold of the default starting word recognition engine to a recognition threshold selected through the sensitivity setting interface.
