Voice Interaction System Device Switching for Call Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In voice interaction systems where a robot and a control apparatus are wirelessly connected, the existing technologies face challenges in seamlessly switching between voice input/output devices during voice interactions, leading to user discomfort when calls arrive, as the voice of the caller is often output from the robot.
Innovation Solution
A voice interaction system comprising an information processing apparatus and a voice interface apparatus connected via short-range wireless communication, allowing the voice input/output unit to switch between devices based on the state of voice interaction, with the process unit managing voice calls and applications, and using Bluetooth for efficient communication and power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot and smart phone are connected by audio connection for voice interaction, then voice interaction functionality is improved, but user comfort deteriorates when calls arrive because caller voice is output from the robot
Solution Approach 1:
The system dynamically switches the voice input/output device based on the operational state. When voice interaction is active, the robot's voice output is used; when a call arrives, the system switches to the smart phone's voice output, thereby adapting to different operational contexts and resolving the conflict between maintaining voice interaction functionality and ensuring user comfort
Solution Approach 2:
The control apparatus acts as an intermediary that manages the audio connection between the robot and smart phone. It receives calls and controls the audio routing, switching the voice output source from the robot to the smart phone when needed, thus mediating between the voice interaction function and user comfort requirement
2Speed
If the robot performs voice interaction independently, then interaction responsiveness is improved, but device complexity increases when managing multiple voice input/output devices
Solution Approach 1:
The voice input/output unit automatically switches between the robot's and smart phone's voice devices based on the operational state without requiring manual intervention. The system self-manages the complexity of multiple devices while maintaining fast and responsive voice interaction, thereby achieving both high responsiveness and simplified user experience

AI summary
A system comprises an apparatus having a first voice I/O device; and a voice interface apparatus having a second voice I/O device, and connected to the apparatus by audio connection via short-range wireless communication, wherein the apparatus includes a voice I/O unit that performs voice input and output by using the first voice I/O device or the second voice I/O device; an interaction unit that performs voice interaction with a user; and a process unit that performs a process other than the voice interaction, by using the voice I/O, and the voice I/O unit switches a device used for the voice input and output to the first voice input/output device in a case where the process unit is brought into a first state in which the voice input and output is required when the voice interaction with the user is performed by using the second voice I/O device.
