AI Device Dynamic Voice Recognition Waiting Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice recognition devices face issues with fixed recognition waiting times, leading to misrecognition of continuous voice commands and unnecessary voice analysis, resulting in deactivated states and user inconvenience.
Innovation Solution
An artificial intelligence device with a processor that recognizes wake-up commands, analyzes subsequent voice commands, and adjusts the recognition waiting time based on the analysis results, optimizing the waiting time for subsequent commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed recognition waiting time is used after wake-up command recognition, then the device can maintain a stable recognition state, but continuous voice commands may not be recognized and unnecessary voice analysis occurs
Solution Approach 1:
The patent applies dynamics by making the recognition waiting time adjustable rather than fixed. The processor dynamically modifies the waiting time based on analysis of the wake-up command and subsequent voice input, allowing the system to adapt between shorter times for continuous commands and longer times for deliberate input, thereby resolving the contradiction between stable operation and ease of continuous operation
Solution Approach 2:
The patent changes the parameter of recognition waiting time from a static fixed value to a dynamic variable. By analyzing the wake-up command and adjusting the waiting time parameter accordingly, the system can optimize recognition behavior for different usage scenarios, improving both reliability and ease of operation for continuous commands
2Ease of operation
If the recognition waiting time is increased to recognize continuous commands, then continuous voice commands can be recognized, but unnecessary voice analysis occurs when user does not issue additional commands
Solution Approach 1:
The system dynamically adjusts the recognition waiting time based on command analysis results. When continuous commands are detected, the waiting time is extended to allow further input; when no additional commands are present, the system returns to a shorter waiting time, thereby reducing unnecessary voice processing and energy consumption while maintaining ease of operation
Solution Approach 2:
The patent implements feedback by analyzing the wake-up command and subsequent voice input to determine whether additional commands are present. This feedback mechanism allows the system to adjust the recognition waiting time appropriately, extending it only when necessary for continuous command recognition and reducing it otherwise to avoid unnecessary processing and energy waste

AI summary
An artificial intelligence device according to an embodiment of the present invention comprises a microphone and a processor configured to recognize a wake-up command received through the microphone, receive a first voice command through the microphone after recognition of the wake-up command, and obtain first analysis result information indicating an intention analysis result of the first voice command, and infer a first waiting time, which is a time the artificial intelligence device waits for reception of an additional voice command after the recognition of the wake-up command based on the first analysis result information.
