Voice Processing System Selective Output for Multi-Device Conversation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple users in the same space use voice devices, issues such as difficulty in listening to other users due to ear closure by voice devices and double hearing of voices occur, leading to a decrease in conversation quality.
Innovation Solution
A voice processing system that includes an acquisition processor to acquire voice inputs from microphones and a setting processor to enable or disable the output of these voices to speakers of other voice devices, based on the type of each voice device, thereby improving conversation quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If earphone-type voice device is used, then the user can have hands-free operation, but the user cannot listen to voices uttered by other users in the same space
Solution Approach 1:
The voice processing system acts as an intermediary that receives voice inputs from multiple users through their respective voice devices and selectively outputs these voices to appropriate devices. When a user wears earphone-type device, the system mediates by transmitting other users' voices to their device, enabling them to listen without removing the earphones.
2Object-affected harmful factors
If desktop-type voice device is used, then the user can directly listen to voices uttered by other users, but the user's voice is reproduced from their own device causing double hearing
Solution Approach 1:
The system extracts and identifies the user's own voice from the mixture of voices captured by the desktop device's microphone. It then separates this self-voice from other users' voices, outputting only other users' voices to the desktop device while suppressing the user's own voice to prevent double hearing.
3Object-affected harmful factors
If voice output function is enabled for all voice devices, then all users can hear each other, but users experience double hearing and conversation quality decreases
Solution Approach 1:
The system applies different voice output settings to different voice devices based on their types and usage contexts. For each device, it selectively determines which voices to output and which to suppress, creating localized quality control tailored to each user's situation rather than applying a uniform setting to all devices.

AI summary
A voice processing system controls voices of a plurality of voice devices arranged in a same space. The voice processing system includes: an acquisition processor that acquires a first voice input to a microphone of a first voice device; and a setting processor that enables or disables a function of outputting the first voice from speakers of one or more other second voice devices for each of the second voice devices.
