Contextual Voice Command Processing Across Portable and Remote Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices have limited speech recognition capabilities and are often not contextually aware, making sophisticated voice-based control functions difficult to implement.
Innovation Solution
The device captures voice commands and contextual information, storing them as digital audio files, and either processes them locally or uploads them to computing equipment with greater processing power and data access for accurate recognition and execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If voice commands are processed locally on portable devices, then processing speed is improved, but processing accuracy and functionality are limited due to insufficient computational power
Solution Approach 1:
The system divides voice processing into two segments: local recording and storage of voice commands on the portable device, and remote processing on a server with greater computational power. This segmentation allows the portable device to maintain simplicity while the server provides advanced processing capabilities for higher accuracy.
Solution Approach 2:
A server acts as an intermediary between the portable device and the voice processing system. The server receives voice commands from the portable device, performs sophisticated speech recognition using neural networks, and returns results. This intermediary enables the portable device to access remote computational resources without requiring local upgrades.
2Weight of moving object
If portable devices have limited processing power, then device portability and battery life are improved, but contextual awareness and sophisticated voice control capabilities are reduced
Solution Approach 1:
The server serves as an intermediary that provides sophisticated contextual awareness and voice control capabilities to portable devices. The server processes voice commands with access to extensive data and contextual information, enabling features like music recommendations and contextual responses without requiring the portable device to have advanced processing power.
Solution Approach 2:
The system enables portable devices to perform multiple sophisticated functions through remote server connectivity. Devices can access various services and data sources via the server, making them multi-functional without requiring each device to have dedicated hardware for each function, thus maintaining portability while enhancing versatility.
3Measurement precision
If voice commands are processed remotely with greater computational resources, then speech recognition accuracy is improved, but processing time and data transmission requirements increase
Solution Approach 1:
The portable device performs preliminary actions by recording and storing voice commands locally before transmission to the server. This allows the device to be ready for immediate processing when connected, reducing the overall time from voice command to response by preparing data in advance.
Solution Approach 2:
The system extracts only the essential voice command data from the portable device and transmits it to the server for processing. By taking out only the necessary information rather than transmitting all device data, the system minimizes transmission time and data requirements while maintaining processing accuracy.
Data Source
AI summary
An electronic device may capture a voice command from a user. The electronic device may store contextual information about the state of the electronic device when the voice command is received. The electronic device may transmit the voice command and the contextual information to computing equipment such as a desktop computer or a remote server. The computing equipment may perform a speech recognition operation on the voice command and may process the contextual information. The computing equipment may respond to the voice command. The computing equipment may also transmit information to the electronic device that allows the electronic device to respond to the voice command.
