Solution Overview

Problem

Conventional voice dialogue systems require users to manually start and end voice input operations, making the process cumbersome and increasing the number of operations needed for each voice input.

Innovation Solution

A voice dialogue method that automatically manages the voice input state, allowing users to input voices without manual operation initiation or termination, by switching the device to a receivable state upon voice input start and reverting after a predetermined period, reducing the need for user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual button pressing is required to start and end voice input, then voice input control is precise, but user operation becomes cumbersome and time-consuming

Engineering Contradiction:
Improveease of voice input operationVSAvoidtime for voice input operation
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The voice input unit automatically manages its own state transitions. When voice input is detected, it switches to the voice input receptacle state and automatically returns to the normal state after a predetermined period or when voice input ends, without requiring manual user intervention to start or stop the input session.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit pre-sets a predetermined period for automatic state transition. This preliminary timing configuration allows the system to automatically manage the voice input session duration, eliminating the need for users to manually control the start and end of each voice input operation.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If automatic state management is implemented, then user operation is simplified, but control precision over voice input timing is reduced

Engineering Contradiction:
Improveease of voice input operationVSAvoidreliability of voice input control
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The control unit continuously monitors the state of the voice input unit and automatically adjusts state transitions based on detected voice input conditions. This feedback mechanism ensures that automatic state management responds accurately to actual voice input occurrences, maintaining control reliability while simplifying user operation.

Inventive Principle:
Principle #23Feedback

AI summary

A voice dialogue method performed by a voice dialogue system includes: a voice signal generation unit; a voice dialogue agent unit; a voice output unit; and a voice input control unit, the method including: a step of, by the voice signal generation unit, receiving a voice input and generating a voice signal based on the received voice input; a step of, by the voice dialogue agent unit, performing voice recognition processing on the voice signal and performing processing based on a result of the voice recognition processing to generate a response signal; a step of, by the voice output unit, outputting a voice based on the response signal; and a step of, when the voice output unit outputs the voice, by the voice input control unit, keeping the voice signal generation unit, for predetermined period after output of the voice, a receivable state in which a voice input is receivable.
