Voice Command Processing Using Steganographic Environmental Cues
Find Innovative SolutionsGenerate Solutions
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, such as audio watermarks, to supplement and clarify voice commands, allowing the system to determine the user's intent without explicit mention of the subject matter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users explicitly identify subject matter in voice commands, then the system can accurately determine user intent, but the interaction becomes cumbersome and error-prone
Solution Approach 1:
The patent introduces steganographically encoded information as an intermediary that bridges the user and the voice-response system. This encoded information, embedded in the environment (such as in media content or surrounding devices), provides contextual data that the system uses to automatically determine user intent without requiring explicit verbal identification of the subject matter, thus resolving the contradiction between accuracy and convenience
Solution Approach 2:
The system performs preliminary action by pre-encoding relevant information about subject matter in the environment using steganography before the user issues a voice command. This advance preparation allows the system to have the necessary contextual information ready when the command is received, enabling accurate intent determination without requiring the user to explicitly state the subject matter
2Measurement precision
If the system monitors for steganographic information in the environment, then it can process voice commands more accurately, but the device complexity increases
Solution Approach 1:
The patent applies self-service by having the environment itself carry the encoded information about subject matter through steganography. Rather than requiring the device to actively search or query for contextual information, the information is passively present in the environment, and the device simply needs to detect and decode it, significantly reducing the complexity of the processing system while maintaining high accuracy

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.
