AI Robot Voice Recognition False Activation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Artificial intelligence robots inadvertently activate their voice recognition function when they hear a wake-up word guidance message from another robot, leading to erroneous operations without user intention.
Innovation Solution
Incorporating voice identification information into wake-up commands to differentiate between user-uttered and robot-uttered commands, preventing activation of the voice recognition function when the command is determined to be from another robot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an artificial intelligence robot outputs a wake-up word guidance message, then users can learn the wake-up word, but another artificial intelligence robot may mistakenly recognize it as a user utterance and activate voice recognition function
Solution Approach 1:
The patent introduces voice identification information as an intermediary element that mediates between the wake-up word guidance message and the voice recognition activation. This intermediary carries source identification data that allows the receiving robot to distinguish whether the wake-up word was uttered by a user or by another robot, thereby preventing false activation while maintaining the guidance function
Solution Approach 2:
The patent applies preliminary action by embedding voice identification information into the wake-up command before it is output as a guidance message. This pre-processing ensures that when another robot receives the message, the source identification is already available, allowing immediate differentiation without requiring additional user input or complex real-time analysis
Data Source
AI summary
An artificial intelligence robot for providing a voice recognition service includes a memory configured to store voice identification information, a microphone configured to receive a voice command; and a processor configured to extract voice identification information from a wake-up command included in the voice command and used to activate the voice recognition service and operate the voice recognition function in a deactivation state when the extracted voice identification information does not match the voice identification information stored in the memory.
