Voice Command Context Prediction for Multi-System Headsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple voice assistance systems, users often face issues where voice commands are either not executed or incorrectly executed due to the lack of identification of the intended voice assistance system.
Innovation Solution
A method and apparatus that predict the intended voice assistance system by analyzing voice commands and presenting images of environments where the systems are located, allowing users to select the correct system without vocal identification, ensuring accurate command execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users issue voice commands without vocal identification in environments with multiple voice assistance systems, then ease of operation is improved, but reliability deteriorates because commands may be executed by the wrong system or not executed at all
Solution Approach 1:
The patent introduces an intermediary system consisting of image generation and display components that mediate between the user's voice command and the multiple voice assistance systems. The system generates visual representations (images or icons) of available voice assistance systems and their locations, allowing the user to select the intended target visually. This intermediary visual interface resolves the contradiction by maintaining ease of operation (no vocal identification needed) while ensuring reliability (correct system selection through visual confirmation).
Solution Approach 2:
The patent transitions the command selection interface from a purely auditory dimension to a visual dimension. Instead of relying solely on voice recognition in acoustic space, the system projects the selection task into visual space by displaying images or icons representing different voice assistance systems and their environmental locations. This dimensional shift allows users to easily select the intended system visually without vocal identification, while ensuring the command reaches the correct system.
2Reliability
If the system presents visual options for selecting voice assistance systems, then reliability is improved by ensuring correct system identification, but device complexity increases due to additional image processing and display components
Solution Approach 1:
The patent implements a universal image generation and display mechanism that serves multiple functions: it identifies voice assistance systems, displays their locations in the environment, and enables user selection. This multi-functional visual interface consolidates what would otherwise require separate systems for system identification, location display, and selection confirmation, thereby improving reliability while limiting the increase in device complexity through functional integration.
3Ease of operation
If the system displays images of environments with voice assistance systems, then ease of operation is improved by enabling visual selection, but loss of time increases due to the additional step of image presentation and user selection
Solution Approach 1:
The patent applies partial action by presenting only a subset of relevant information to the user - specifically, visual images or icons of the voice assistance systems and their locations, rather than displaying all possible system parameters or environmental details. This selective visual presentation maintains ease of operation by showing only the essential selection criteria while minimizing the time required for image processing and user decision-making.
Data Source
AI summary
A method includes determining a plurality of voice assistance systems located in a plurality of environments and receiving, from a headset of a user, a voice command from the user. The voice command lacks an identifier for a first voice assistance system of the plurality of voice assistance systems in a first environment of the plurality of environments. The method also includes predicting, based on the voice command, a subset of the plurality of voice assistance systems for executing the voice command and communicating, to the headset, images of environments of the plurality of environments in which the subset of the plurality of voice assistance systems are located. The method further includes detecting that the user selected, from the images, an image of the first environment that contains the first voice assistance system and in response, communicating the voice command to the first voice assistance system.
