Solution Overview

Problem

Existing technologies face challenges in easily controlling electronic devices, particularly in environments with external noise or multiple users, where voice recognition systems struggle to authenticate user authority and prioritize control instructions effectively.

Innovation Solution

An electronic device and method that utilize voice signals to authenticate user authority, extract voice parameters, and register users based on trigger signals, allowing for controlled operation even in noisy conditions and multiple user scenarios, with prioritization based on use patterns and preset criteria.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If voice recognition is used to control electronic devices, then ease of operation is improved, but reliability deteriorates in noisy environments or with multiple users

Engineering Contradiction:
Improveease of operationVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary user registration by storing voiceprints and associated user information before actual voice control operations. This preliminary action enables the system to reliably identify users during subsequent control operations, resolving the reliability issue in noisy environments or with multiple users while maintaining ease of operation.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If voice control is enabled for multiple users, then adaptability is improved, but device complexity increases due to authentication requirements

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements self-service through automatic voiceprint extraction and user identification. When a user speaks a command, the system automatically extracts the voiceprint, compares it with registered users, and executes the appropriate control actions without requiring manual authentication steps. This maintains adaptability for multiple users while minimizing perceived device complexity.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If voice parameters are extracted and stored for authentication, then measurement precision is improved, but loss of time increases during registration

Engineering Contradiction:
Improvemeasurement precisionVSAvoidloss of time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The voice parameter extraction and storage is performed as a preliminary registration action that occurs only once per user. Although this initial process requires time for collecting and storing multiple voice parameters, it establishes high measurement precision for subsequent authentication. The one-time time investment enables rapid and accurate user identification during all future voice control operations.

Inventive Principle:
Principle #10Preliminary action
