Dialogue Audio Control With Real-Time Ambient Sound Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speech recognition technologies lack the ability to provide a natural dialogue experience by integrating ambient sounds in real time with system responses, limiting the sense of presence and immersion for users.
Innovation Solution
A user terminal and dialogue management system that includes microphones to collect ambient sounds and outputs system responses together with ambient sounds matching user voice commands, utilizing a controller to manage communication with servers for ambient sound provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If speech recognition technology is used to identify user intention from voice, then service provision capability is improved, but natural dialogue experience and sense of presence deteriorate due to lack of ambient sound integration
Solution Approach 1:
The patent merges system response output with ambient sound output into a single integrated audio output process. The controller combines the system response signal and the captured ambient sound signal, then outputs them simultaneously through the speaker, creating a unified audio experience that maintains service reliability while enhancing natural dialogue perception.
Solution Approach 2:
The ambient sound acts as an intermediary element that bridges the gap between the system response and the user's perception of natural dialogue. By introducing ambient sound as a mediator, the system creates a more immersive auditory environment that enhances the sense of presence without interfering with the core speech recognition functionality.
2Speed
If system response is output to user voice command, then service responsiveness is improved, but sense of presence deteriorates without ambient sound integration
Solution Approach 1:
The system merges the fast system response output with the concurrently captured ambient sound into a single audio stream. This combination maintains the rapid responsiveness of the system while adding the immersive quality of ambient sounds, thereby enhancing the sense of presence without sacrificing service speed.
Solution Approach 2:
The ambient sound capture is performed in parallel and preliminarily alongside the system response generation. By preparing the ambient sound signal simultaneously with the system response, the system ensures that both signals are ready for immediate combined output, maintaining fast responsiveness while enriching the auditory experience.
3Reliability
If ambient sound is collected using multiple microphones in vehicle, then ambient sound collection capability is improved, but device complexity increases
Solution Approach 1:
The patent segments the microphone system into functionally distinct groups: a first microphone dedicated to capturing user voice commands and second microphones dedicated to capturing ambient sounds. This segmentation allows each microphone to be optimized for its specific function and simplifies the control logic by clearly separating voice processing from ambient sound processing pathways.
Solution Approach 2:
The controller is designed with multi-functionality to handle both voice command processing and ambient sound management. By integrating these functions into a single control unit, the system avoids the need for separate dedicated controllers, thereby reducing overall device complexity while maintaining reliable ambient sound collection capabilities.

AI summary
A user terminal, a control method thereof, a dialogue management system and a dialogue management method may output an ambient sound related to a user intention in real time together with a system response to a user's voice command, thereby providing a user with a sense of presence and enabling a natural dialogue with the user.The user terminal includes at least one microphone; a speaker; a communication module configured to communicate with a server; and a controller configured to control the speaker to output a system response corresponding to a voice command of a user, when the user's voice command is input through the at least one microphone, wherein the controller is configured to control the speaker to output an ambient sound matching the voice command together with the system response.
