Voice Recording Equipment Dynamic Threshold Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Speakers in noisy environments often fail to adjust their voice levels during voice recording sessions, leading to suboptimal high-definition audio quality due to the need for louder speaking, which may not be immediately recognized.
Innovation Solution
A voice recording equipment with a voice processing unit that monitors sound intensities and adjusts threshold values to prompt speakers when their voice levels are insufficient, incorporating modules for threshold computation, determination, and real-time updates to ensure optimal recording conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the voice recording equipment operates in a noisy environment, then the speaker must speak loudly to maintain audio quality, but the speaker may not realize they need to raise their voice level
Solution Approach 1:
The patent implements a feedback mechanism where the voice recording equipment monitors the speaker's voice level in real-time and provides visual or audible feedback to indicate when the voice level is too low. This allows the speaker to adjust their voice level without needing to consciously monitor the environment, resolving the contradiction between maintaining audio quality and the difficulty of detecting appropriate voice levels in noisy environments.
2Measurement precision
If the speaker speaks loudly in a noisy environment, then high definition audio can be created, but the speaker needs to consciously regulate voice level which is difficult to achieve
Solution Approach 1:
The voice recording equipment performs self-service by automatically monitoring voice levels and providing feedback to the speaker. The system takes responsibility for detecting when voice levels are insufficient and guides the speaker to adjust, eliminating the need for the speaker to consciously regulate their voice level while still achieving high definition audio quality.
3Measurement precision
If the surrounding environment is silent, then high definition audio can be created with low voice speaking, but in noisy environments the speaker must speak loudly
Solution Approach 1:
The system continuously monitors environmental noise levels and provides feedback to the speaker when voice levels are insufficient relative to the background noise. This allows the speaker to maintain natural speaking levels while the system compensates by alerting them when adjustment is needed, preserving audio quality regardless of environmental noise conditions.
Data Source
AI summary
In a voice recording equipment and method, voice data from a speaker is received using a microphone. Threshold values T1 and T2 of surrounding environment of the voice recording equipment are determined. If an intensity of the voice data is less than or equal to the threshold value T2, the voice recording is stopped and the speaker is informed that the voice data is not useful. If the intensity of the voice data is greater than the threshold values, the voice data is stored into a storage unit.
