Conference Server Voice Routing for Private Assistant Responses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual assistants in online conferences may inadvertently share user commands or responses with other participants, leading to privacy concerns and unwanted exposure of personal interactions.
Innovation Solution
A conference server that includes a processor to acquire and process voice commands, excluding them from output signals, and a communication interface to transmit response voices selectively, allowing users to choose between personal and sharing modes for voice transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the virtual assistant's response voice is shared with all conference participants, then the support function is improved, but user privacy is compromised
Solution Approach 1:
The conference participants are segmented into different groups: the user who invokes the virtual assistant, other participants, and the virtual assistant itself. The response voice transmission is segmented to be sent only to the invoking user's terminal, not broadcast to all participants. This segmentation resolves the contradiction by allowing the virtual assistant function to work while protecting user privacy through selective information distribution.
2Loss of information
If all voice signals are transmitted to all participants, then communication completeness is improved, but information security deteriorates
Solution Approach 1:
Different quality of voice signal transmission is applied to different participants. The invoking user receives complete voice signals including virtual assistant responses, while other participants receive only the original conference audio without the virtual assistant's private responses. This local quality differentiation ensures information security while maintaining communication completeness for those who need it.

AI summary
A conference server includes a processor configured to acquire a response voice signal according to a command voice signal included in a first input voice signal transmitted from a first communication device that participates in an online conference and output a first output voice signal including a command-excluded voice signal obtained by excluding the command voice signal from the first input voice signal; and a communication interface configured to receive the first input voice signal transmitted from the first communication device, transmit the response voice signal to the first communication device, and transmit the first output voice signal to the other communication device that participates in the online conference.
