Vehicle Voice Command Classification for Touch Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice command processing devices for vehicles fail to effectively classify voice commands into control and touch-based commands, leading to low recognition rates and inability to perform desired operations, as they do not differentiate between control and touch-based commands and lack functionality to select objects on a touch display.
Innovation Solution
A device and method that classify voice commands into control and touch-based commands, using a controller to identify objects on a touch display and process these commands separately, with a communication module to transmit voice commands to a voice recognition server and a touch-based command processing module to select objects on the display based on the recognized commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice commands are processed without classification into control and touch-based commands, then the processing system remains simple, but the recognition rate is low and desired operations cannot be performed
Solution Approach 1:
The patent segments voice commands into two distinct types: control commands and touch-based commands. This segmentation allows the system to process each type appropriately, improving recognition accuracy. The controller classifies incoming voice commands and routes them to different processing pathways, ensuring that control commands execute device operations while touch-based commands select objects on the display.
2Adaptability or versatility
If the system only processes control commands without touch-based command functionality, then the processing logic remains simple, but the system cannot select objects on the touch display
Solution Approach 1:
The patent divides the command processing functionality into separate modules: a control command processing module for executing device control operations and a touch-based command processing module for selecting objects on the display. This modular segmentation enables the system to handle both control and touch-based commands, significantly improving adaptability and versatility.
Solution Approach 2:
The controller acts as an intermediary that receives voice commands, classifies them into control or touch-based types, and routes them to the appropriate processing module. This intermediary function enables seamless integration between voice recognition and the dual-processing architecture, allowing the system to perform both device control and object selection operations.
3Productivity
If a single processing module handles all voice commands, then the device complexity is low, but the productivity and accuracy of voice command processing are reduced
Solution Approach 1:
The patent implements parallel processing modules that operate simultaneously: the control command processing module handles device control operations while the touch-based command processing module handles object selection. This parallel segmentation increases processing throughput and efficiency, as multiple command types can be handled concurrently without sequential bottlenecks.

AI summary
A device for processing a voice command for a vehicle includes: a communication module to transmit a voice command received from a user to a voice recognition server, and to receive a recognized voice command from the voice recognition server; a controller identifying objects displayed on a screen of a touch display, and classifying the recognized voice command into a control command and a touch-based command; a control command processing module to perform a control operation corresponding to the control command; and a touch-based command processing module for selecting an object corresponding to the touch-based command from the touch display.
