Solution Overview

Problem

Current dialog systems lack the ability to artificially recreate scenarios where multiple individuals respond to a single utterance, failing to provide a realistic and engaging interaction with users.

Innovation Solution

A dialog device that includes an acquisition unit for user input, multiple generation units for generating system utterances based on different scenarios, and an output unit that presents these utterances in distinct expression formats, allowing multiple agents with different characters to interact with the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single generation unit is used to respond to user utterance, then the system structure is simple, but it cannot express multiple people responding to one utterance

Engineering Contradiction:
Improveability to express multiple people respondingVSAvoidsystem structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the dialog generation function into multiple independent generation units (first generation unit and second generation unit), where each unit is responsible for generating responses from different agents with distinct scenarios. This segmentation enables the system to express multiple people responding to one utterance while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple generation units are designed with universal interfaces and standardized output formats, allowing them to perform different specialized functions (different agents/scenarios) while integrating seamlessly into the same system architecture. This multi-functionality approach enables versatile expression of multiple responders without proportionally increasing system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple generation units with different scenarios are used, then a realistic multi-person dialog scene can be created, but the system complexity increases

Engineering Contradiction:
Improvedialog scenario diversityVSAvoidnumber of generation units
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each generation unit is assigned a specific local quality or specialization (different scenario and agent character), such as the first generation unit handling customer service scenarios and the second generation unit handling technical support scenarios. This local quality assignment allows diverse dialog scenarios to be created while keeping each unit's internal complexity manageable and focused.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system uses multiple copies of the generation unit architecture, where each copy is instantiated with different scenario parameters and agent characteristics. This copying approach enables scenario diversity by reusing the same structural template with different configurations, rather than creating entirely different complex systems for each scenario.

Inventive Principle:
Principle #26Copying

3Adaptability or versatility

If multiple agents with different characters talk continuously, then user engagement is enhanced, but the processing time increases

Engineering Contradiction:
Improveuser interaction realismVSAvoiddialog processing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-configuring multiple generation units with their respective scenarios, agent characters, and response templates before actual user interaction begins. This advance preparation allows the system to quickly switch between different agents and scenarios during dialog without incurring significant processing delays, thus enhancing user engagement while minimizing time loss.

Inventive Principle:
Principle #10Preliminary action

AI summary

A dialog device according to an embodiment includes an acquisition unit configured to acquire a user utterance input by a user, a plurality of generation units configured to generate a system utterance corresponding to the user utterance, and an output unit configured to output the system utterance generated by one generation unit selected from the plurality of generation units. The plurality of generation units include a first generation unit having a first scenario and a second generation unit having a second scenario different from the first scenario. The output unit outputs a first system utterance generated by the first generation unit in response to the user utterance, in a first expression format, and outputs a second system utterance generated by the second generation unit in response to the user utterance, in a second expression format different from the first expression format, following the first system utterance.
