Voice Control System Partial Matching for Location Reminders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice control systems for terminals lack flexibility in executing control instructions, as they require exact voiceprint matching before performing operations, limiting their ability to recognize variations in voice patterns due to environmental changes or user authentication.
Innovation Solution
A method that extracts a target voiceprint feature from a user's voice, determines if it meets a preset condition relative to a preset voiceprint feature, and triggers a location reminder by adjusting the ringtone volume based on environmental noise, allowing flexible voice control operations even if the voiceprint does not exactly match, such as by using a ringtone with increasing volume if not found within a preset duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exact voiceprint matching is required before executing control instructions, then voice control security is improved, but voice control flexibility deteriorates
Solution Approach 1:
The patent applies partial matching by determining whether a target voiceprint feature meets a preset condition relative to a preset voiceprint feature, rather than requiring exact matching. This allows the system to recognize voice commands even when there are variations in voice patterns due to environmental changes or user authentication, thereby improving flexibility while maintaining security through condition-based validation
Solution Approach 2:
The patent changes the matching parameter from exact equality to condition-based comparison. By determining if the target voiceprint feature meets a preset condition (such as similarity threshold) rather than requiring exact match, the system adapts to voice variations while maintaining security standards
2Measurement precision
If voiceprint recognition threshold is set high, then authentication accuracy is improved, but recognition speed deteriorates
Solution Approach 1:
The patent performs preliminary voiceprint feature extraction and condition determination before executing control instructions. By pre-processing the voice signal to extract features and compare them against preset conditions, the system optimizes the recognition flow to balance accuracy and speed
3Reliability
If ringtone volume is increased to ensure audio clarity, then location reminder effectiveness is improved, but environmental noise interference increases
Solution Approach 1:
The patent applies dynamic volume adjustment where the ringtone volume is not fixed but adapts based on environmental conditions. The system determines a target volume value according to the noise value of the current environment, allowing the reminder to be audible over background noise while avoiding excessive volume in quiet environments

AI summary
Disclosed in the present disclosure is a location reminder method, comprising: after receiving voice used for searching for a terminal, extracting target voice print features from the voice; if the target voice print features do not match preset voice print features, and the target voice print features and the preset voice print features meet a preset condition, then detecting whether the terminal is located at a preset location; and, if the terminal is located at the preset location, then reminding the user of the current location of the terminal according to a preset method.
