Solution Overview

Problem

Existing voice-response systems require users to explicitly identify the subject matter of their environment in voice commands, which can be cumbersome and prone to errors.

Innovation Solution

Utilize steganographically encoded information in the user's environment to supplement and clarify voice commands, allowing the system to ascertain the subject matter automatically and enhance command processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users explicitly identify the subject matter in voice commands, then the system can accurately process the command, but the interaction becomes cumbersome and error-prone

Engineering Contradiction:

Improvecommand processing accuracyVSAvoiduser interaction convenience

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system performs preliminary action by extracting steganographic information from the environment before processing the voice command. This pre-extracted context information is then used to automatically identify the subject matter, eliminating the need for users to explicitly state it and thereby improving both accuracy and convenience

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Steganographic information acts as an intermediary between the user's implicit intent and the system's command processing. The hidden information in the environment provides contextual clues that bridge the gap between what the user says and what they actually mean, enabling accurate interpretation without explicit identification

Inventive Principle:

Principle #24Intermediary (Mediator)

2Extent of automation

If the system monitors for steganographic information in the environment, then it can automatically determine user intent, but the system complexity increases

Engineering Contradiction:

Improveautomatic intent determinationVSAvoidsystem processing complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The system uses self-service by leveraging already-present steganographic information in the environment rather than requiring active sensing or complex processing. The hidden information serves the system's needs automatically, providing context without requiring the system to actively search or interpret complex environmental data

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses copying by extracting and utilizing information that has already been encoded in the environment through steganography. This pre-encoded information is copied and applied to the voice command processing, avoiding the need for complex real-time environmental analysis while achieving automatic intent determination

Inventive Principle:

Principle #26Copying

AI summary

A method and system for voice-command processing based on steganographically encoded information. In an example method, a computing system receives a voice command spoken by a user, and the computing system also extracts information from steganographic encoding in an environment of the user. The computing system then uses the information extracted from the steganographic encoding in the environment of the user as a basis for the computing system to process the received voice command spoken by the user. Further, the computing system takes action based on the processing of the voice command.
