Context-Aware Voice Command Offloading for Portable Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices have limited speech recognition capabilities, processing power, and are often not contextually aware, making sophisticated voice-based control functions difficult.
Innovation Solution
The device captures voice commands and contextual information, storing them locally or remotely for processing using more powerful computing equipment with access to extensive data and resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If voice command processing is performed locally on the portable device, then response time is reduced, but processing power and accuracy are insufficient
Solution Approach 1:
The patent introduces a remote server as an intermediary between the portable device and the voice processing system. The portable device captures voice commands and transmits them to the remote server, which performs the complex speech recognition and contextual processing. This mediator approach allows the portable device to maintain simplicity while achieving high processing accuracy through the remote server's computational resources.
Solution Approach 2:
The patent transitions voice processing from a local two-dimensional operation (microphone to processor) to a three-dimensional distributed system involving the portable device, communication network, and remote server. This dimensional expansion enables access to extensive data and computing resources that would be unavailable on the portable device alone, thereby improving processing accuracy without constraining the portable device's hardware limitations.
2Measurement precision
If contextual information is stored and transmitted, then voice command accuracy is improved, but data transmission requirements increase
Solution Approach 1:
The patent extracts only the essential contextual information needed for accurate voice command processing and transmits merely this extracted data to the remote server. By taking out only the necessary contextual elements rather than transmitting all possible device state data, the system achieves improved voice command accuracy while minimizing data transmission volume and associated bandwidth requirements.
3Adaptability or versatility
If sophisticated voice-based control functions are implemented, then device functionality is enhanced, but device complexity increases
Solution Approach 1:
The remote server acts as an intermediary that handles the complex processing requirements of sophisticated voice-based control functions. The portable device simply captures voice commands and transmits them, while the server performs speech recognition, contextual analysis, and executes complex control operations. This mediator approach enables enhanced functionality without increasing the portable device's processing complexity.
Solution Approach 2:
The patent extracts complex processing tasks from the portable device and relocates them to the remote server. By taking out speech recognition, contextual processing, and control execution to the server, the system achieves sophisticated voice-based control functionality while maintaining the portable device's simplicity and reducing its processing complexity.
