Audio Component Ratio Control for Clear Speech at Low Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in adjusting specific audio components while reducing volume, as existing electronic apparatuses decrease all audio components uniformly, leading to discomfort in hearing important elements like performer's lines during movies or news commentary.
Innovation Solution
An electronic apparatus that estimates user intent to emphasize specific audio components by changing the ratio of first and second audio components based on volume adjustments, ambient conditions, and content type, without requiring direct user manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the volume of audio is reduced to avoid disturbing others at night, then the noise level decreases and does not disturb anyone, but all audio components including important information-carrying elements like performer's lines are also decreased making them difficult to hear
Solution Approach 1:
The audio signal is segmented into multiple components including speech components and non-speech components. The controller separates these components and applies different volume adjustments to each, allowing speech components to be maintained at higher levels while reducing overall noise disturbance.
Solution Approach 2:
Different quality settings are applied to different audio components. Speech components receive enhanced processing and higher volume levels to ensure information clarity, while non-speech components are reduced more aggressively to minimize disturbance to others.
2Loss of information
If the user manually adjusts each audio component through the menu to hear important elements clearly, then the audibility of important audio components improves, but the operation complexity increases and user convenience decreases
Solution Approach 1:
The controller automatically performs audio component separation and volume adjustment without requiring manual user intervention. The system self-adjusts speech and non-speech component levels based on detected user needs, eliminating the need for users to navigate menus and manually configure each audio parameter.
Solution Approach 2:
The system monitors user interactions and audio playback conditions, then automatically adjusts audio component levels in response. This feedback mechanism allows the system to learn from user behavior patterns and make intelligent adjustments to prioritize speech components without explicit user commands.

AI summary
An electronic apparatus and a method for controlling the electronic apparatus are provided. The electronic apparatus includes an audio processor that outputs an audio including a first audio component and a second audio component and a controller that controls the audio processor to change a ratio of the first audio component to the second audio component according to the changed audio level, in response to receiving an instruction to change a level of the output audio.
