Voice Volume Adjustment Using Scene-Aware Amplitude Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for adjusting volume in electronic devices using voice recognition are inflexible, requiring multiple interactions between the user and the device to achieve suitable volume levels, as they rely on fixed amplitude adjustments regardless of environmental or user-specific conditions.
Innovation Solution
A method and system that acquire audio signals with adjustment instructions and corresponding scene information to dynamically determine and apply different amplitudes based on scene-specific parameters, such as noise levels and user characteristics, allowing for flexible and efficient volume adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed amplitude adjustment is used for volume control, then the control method is simple, but the adaptability to different scenes and user conditions deteriorates
Solution Approach 1:
The patent applies dynamics by making the volume adjustment amplitude variable rather than fixed. The system dynamically determines adjustment amplitudes based on scene information (such as environment type, location, time) and user characteristics (age, hearing ability), allowing the control method to adapt to different conditions while maintaining operational simplicity through automated scene recognition.
Solution Approach 2:
The patent changes the parameter of adjustment amplitude from a fixed value to a variable determined by multiple factors including scene type, user profile, and historical interaction data. This parameter change enables the system to optimize volume adjustments for different scenarios (e.g., larger adjustments in noisy environments, smaller adjustments for elderly users) while keeping the user interface simple.
2Device complexity
If fixed amplitude adjustment is used, then the system complexity is low, but the number of interactions required increases
Solution Approach 1:
The system performs preliminary actions by pre-acquiring scene information and user profile data before executing volume adjustment. It proactively determines the optimal adjustment amplitude based on the current scene and user characteristics, eliminating the need for multiple trial adjustments and reducing interaction time.
Solution Approach 2:
The patent implements feedback mechanisms by monitoring user responses to volume adjustments and using this information to refine future adjustments. The system learns from interaction patterns and scene contexts to optimize the number of adjustments needed, reducing time loss while managing system complexity through intelligent algorithms.
3Adaptability or versatility
If scene-specific dynamic amplitude is implemented, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The patent segments the volume control system into distinct functional modules: scene recognition module, user profile management module, amplitude calculation module, and execution module. This segmentation allows each component to handle specific tasks independently, improving adaptability to different scenes while managing overall system complexity through modular architecture.
Solution Approach 2:
The system applies self-service by automatically acquiring scene information, retrieving user profiles, calculating optimal amplitudes, and executing adjustments without requiring manual user configuration. This automation enhances scene-specific adaptability while containing complexity through integrated self-configuration capabilities.
