Conference Audio Feedback for Source-Side Issue Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Participants in online conferences often face difficulties in hearing speech due to low audio levels or excessive noise in the audio data, with the cause being unclear whether it originates from the transmitting or receiving side.
Innovation Solution
An information processing device determines audio levels across multiple terminals, selects devices with low audio levels, and notifies users to adjust settings or identify defects in their devices to improve audio quality.

Engineering Contradiction Analysis
1Reliability
If audio data is transmitted from terminal devices in an online conference system, then speech communication is enabled, but it becomes difficult to identify whether low audio level or noise is the cause of hard-to-hear speech
Solution Approach 1:
The patent implements a feedback mechanism where each terminal device evaluates the audio level of received audio data from other devices and transmits evaluation results back to the source device. This feedback loop enables the system to identify whether audio quality issues originate from transmission or reception sides by analyzing evaluation results from multiple devices.
Solution Approach 2:
The patent introduces an evaluation result as an intermediary element that mediates between the audio transmission process and the quality assessment. This intermediary carries information about audio quality metrics (audio level, noise presence) from receiving devices back to transmitting devices, enabling cause identification without direct inspection of the audio data itself.
2Reliability
If a user can ascertain whether their information has been appropriately transmitted, then transmission reliability is improved, but during periods when no participant speaks, it cannot be ascertained whether speech based on audio data can be heard
Solution Approach 1:
The patent performs preliminary audio level evaluation and noise detection on audio data before actual speech transmission occurs. By evaluating audio quality metrics in advance (when participants are not speaking but audio data is being transmitted), the system can identify and notify participants about potential audio quality issues before they affect communication, eliminating the verification gap during silent periods.

AI summary
An information processing device includes a first determination unit to compare between audio levels of audio data based on speech contents transmitted from at least two different information processing devices other than the information processing device and a determination target; a selection unit to select an information processing terminal on the basis of the determination result; a first transmission unit to transmit an evaluation result to the selected information processing terminal; a first reception unit to receive the evaluation result from different information processing devices other than the information processing device; and a second determination unit to determine whether there is a cause the audio level has not reached the criterion in the information processing device or a different information processing device which is a source of the evaluation result on the basis of the received evaluation result. The information processing device outputs a notification based on the determination result.
