Multi-Agent Audio Coordination for Audiobook and Music Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for utilizing services from multiple agents, such as those described in Japanese Patent Application Laid-Open (JP-A) No. 2018-189984, do not facilitate convenient simultaneous use of these services, particularly in scenarios where multiple agents provide audio interactions like audiobook and music playback.
Innovation Solution
An agent coordination device with a processor and memory that controls sound output to reduce the music playback volume of one agent when another agent is already performing audiobook or music playback, allowing for simultaneous and intelligible use of services from multiple agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple agents perform audio services simultaneously at full volume, then service availability is improved, but audio intelligibility deteriorates
Solution Approach 1:
The system dynamically adjusts the volume level of background music based on whether audiobook playback is active. When audiobook playback is detected, the music volume is automatically reduced to a lower level, allowing both services to operate simultaneously while maintaining audio intelligibility. This dynamic parameter adjustment resolves the contradiction between service availability and audio clarity.
2Manufacturing precision
If music playback volume is maintained at high level during audiobook playback, then music quality is improved, but audiobook audibility deteriorates
Solution Approach 1:
The system applies different volume quality levels to different audio services based on their current playback state. When audiobook playback is active, music volume is locally adjusted to a lower level specifically in the frequency range that would interfere with speech intelligibility, while maintaining overall music quality. This localized adjustment resolves the contradiction between music quality and audiobook audibility.

AI summary
An agent coordination device that controls sound output according to an instruction from a plurality of agents that are capable of being instructed to perform a predetermined service by speech interaction; and controls so that, in a case in which a first agent among the plurality of agents is performing one of audiobook playback or music playback as the predetermined service while a second agent among the plurality of agents is performing another of audiobook playback or music playback as the predetermined service, audiobook playback is performed with a music playback volume reduced.
