Voiceprint-Based Master Response Control for Shared Voice Commands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple intelligent voice control devices, all devices unintentionally respond to a single user's voice command due to lack of differentiation, leading to resource waste and inefficiency.
Innovation Solution
A method and apparatus determine a master responsive voice control device based on user positioning devices using voiceprint recognition and distance measurement, ensuring only the designated device responds to the user's command.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple intelligent voice control devices are deployed in a smart home environment, then the coverage and functionality of the voice control system is improved, but the accuracy of voice command recognition deteriorates because all devices may respond unintentionally
Solution Approach 1:
The patent segments the response function among multiple voice control devices by assigning a master device and slave devices. The master device receives and processes voice commands, while slave devices remain silent. This segmentation resolves the contradiction by maintaining wide coverage through multiple devices while ensuring precise command recognition through centralized processing.
Solution Approach 2:
The patent introduces a master voice control device as an intermediary between the user's voice command and the slave devices. The master device acts as a mediator that receives the voice command, processes it, and then controls which slave devices should respond, preventing unintentional responses while maintaining system coverage.
2Productivity
If all intelligent voice control devices respond to every voice command, then the responsiveness of the system is improved, but the reliability of the control system deteriorates due to unintentional activations
Solution Approach 1:
The patent applies preliminary action by having the master voice control device process and prepare the voice command before it is executed by slave devices. This preliminary processing step ensures that only appropriate commands are forwarded to slave devices, maintaining responsiveness while preventing unreliable unintentional activations.
Solution Approach 2:
The patent implements feedback mechanisms where the master device monitors and controls which slave devices should respond to voice commands. This feedback loop ensures that slave devices only respond when appropriate, maintaining system responsiveness while improving reliability by preventing incorrect activations.
3Measurement precision
If voice print recognition is used to identify users, then the accuracy of user identification is improved, but the device complexity increases
Solution Approach 1:
The patent merges the voice print recognition function into the master voice control device, combining user identification with command processing in a single device. This merging approach improves user identification accuracy while minimizing the increase in overall system complexity by consolidating functions rather than distributing them across multiple devices.

AI summary
Embodiments of the present disclosure provide a method and an apparatus for controlling an intelligent voice control device and a storage medium. The method for controlling an intelligent voice control device is applicable for the intelligent voice control device, the method includes: in response to receiving a control voice issued by a user, determining (S11) whether the intelligent voice control device is a master responsive intelligent voice control device; and when the intelligent voice control device is the master responsive intelligent voice control device, responding (S12) to the control voice. With the present disclosure, it is possible to prevent a plurality of intelligent voice control devices from simultaneously responding to the control voice issued by the user.
