Audio Volume Adjustment for Echo-Aware Remote Transcription
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to consistently adjust audio signal volumes above the noise floor during communication sessions, particularly for echo signals, which can hinder transcription accuracy in remote transcription systems.
Innovation Solution
A method is implemented to continuously adjust the volume of audio signals to a specific level above the noise floor, distinguishing between echo and primary audio signals to ensure consistent volume for echo signals, thereby aiding transcription systems in identifying and processing audio correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If audio signal volume is not adjusted, then the system operation is simple, but transcription accuracy deteriorates due to inconsistent volume levels and noise floor issues
Solution Approach 1:
The system performs preliminary volume adjustment of audio signals before they are processed by the transcription system. By pre-adjusting the volume to a consistent level above the noise floor, the system ensures that transcription accuracy is improved without requiring complex real-time adjustments during transcription processing.
Solution Approach 2:
The system changes the volume parameter of audio signals to optimize transcription accuracy. By adjusting the volume level to be consistently above the noise floor, the system improves the quality of input signals for transcription while maintaining relatively simple processing logic.
2Measurement precision
If echo signals are not distinguished and adjusted separately, then the processing logic is simple, but transcription accuracy deteriorates due to inconsistent echo signal volumes
Solution Approach 1:
The system segments audio signals into different types, specifically distinguishing between echo signals and other audio signals. By separating echo signals for special volume adjustment, the system improves transcription accuracy for this specific signal type while maintaining simple processing for other signals.
Solution Approach 2:
The system applies different volume adjustment strategies to different signal types. Echo signals receive specific volume adjustment to ensure consistency, while other signals are processed differently. This localized quality approach improves overall transcription accuracy without requiring complex uniform processing of all signals.

AI summary
A method to adjust volume may include obtaining an audio signal during a communication session between a first device and a second device. The method may also include adjusting a volume level of the audio signal so that the volume level is a particular volume level above a noise floor of the audio signal and directing the adjusted audio signal to a remote transcription system.
