Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing verbal command processing systems fail to accurately differentiate between users and enforce permissions, leading to unauthorized command execution when multiple users share the same verbal commands.

Innovation Solution

An apparatus and method that utilize a phoneme module to select recognition phonemes, a user recognition module to identify the user based on these phonemes, and a command module to process commands concurrently, ensuring that only authorized users can execute specific commands by referencing user profiles that include permissions and customized actions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If verbal command processing is implemented without speaker recognition, then the system is simple and easy to operate, but it cannot differentiate between users and enforce permissions

Engineering Contradiction:

Improveuser authentication accuracyVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges speaker recognition technology with verbal command processing systems. The speaker recognition module is integrated into the command processing pipeline, allowing the system to simultaneously perform voice-based user identification and command interpretation. This combination enables reliable user differentiation without requiring separate authentication systems, thus improving security while maintaining operational simplicity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If speaker recognition is added to verbal command processing, then user differentiation and permission enforcement are enabled, but the system complexity increases

Engineering Contradiction:

Improveuser-specific command processingVSAvoidmodule structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the verbal command processing system into distinct functional modules: a speaker recognition module for user identification, a verbal command processing module for command interpretation, and a command execution module for action implementation. Each module operates independently with defined interfaces, allowing the system to handle multiple user-specific commands while maintaining manageable complexity through modular architecture.

Inventive Principle:

Principle #1Segmentation

3Reliability

If multiple users share the same verbal commands, then the system is easy to operate, but unauthorized command execution occurs

Engineering Contradiction:

Improvecommand execution securityVSAvoidcommand usage

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the speaker recognition module continuously provides user identity information to the command processing module. The system compares the recognized speaker against authorized users for each command, providing real-time verification feedback. This ensures that only authorized users can execute specific commands while maintaining the simplicity of voice-based operation for all users.

Inventive Principle:

Principle #23Feedback

AI summary

For verbal command processing, a phoneme module selects recognition phonemes from a phoneme input stream. A user recognition module selects a user profile for a user recognized based on the recognition phonemes. The command module processes a command concurrently identified from the phoneme input stream based on the user profile.
