Voice Recognition Engine for Extracting Navigation Destinations from Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems require drivers to divert attention from the road to memorize or write down destination addresses provided during phone calls, as they cannot directly extract destinations from voice data from remote parties.
Innovation Solution
A navigation system that connects a hands-free communication unit with a voice recognition engine over a communication network, allowing voice data from remote parties to be processed and converted into navigation or call destinations, enabling drivers to input routes or call information without manual distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver manually inputs the destination address during a telephone call, then the navigation system can provide routing guidance, but the driver's attention is severely distracted from the road
Solution Approach 1:
The patent introduces a message processing system that acts as an intermediary between the telephone conversation and the navigation system. The system captures messages from the telephone call, automatically processes them through voice recognition or text parsing, and extracts destination information without requiring the driver to manually input data. This mediator handles the destination input task, freeing the driver from distraction while maintaining navigation functionality.
Solution Approach 2:
The navigation system performs self-service by automatically processing telephone messages to extract destination information. The system includes automated message capture, voice recognition processing, and destination extraction capabilities that operate without driver intervention. This self-service mechanism allows the system to obtain destination data autonomously during telephone calls, eliminating the need for manual driver input and associated distractions.
2Loss of information
If the driver memorizes the destination address during a telephone call, then the destination can be input into the navigation system, but the driver's attention is severely distracted
Solution Approach 1:
The message processing system serves as an intermediary that captures and retains destination information directly from the telephone message source. Instead of relying on the driver's memory, the system intercepts the message, processes it through automated recognition, and stores the destination data for navigation use. This intermediary approach eliminates the need for driver memorization while maintaining information accuracy.
Solution Approach 2:
The patent replaces the mechanical process of human memorization with an automated electronic message processing system. The system uses voice recognition technology and text parsing algorithms to capture, process, and retain destination information from telephone messages. This substitution of mechanical human cognition with automated electronic processing eliminates the distraction of memorization while ensuring accurate information retention.
3Loss of information
If the party on the other side of the conversation sends a message containing the address through wireless messaging service, then the navigation system can extract the destination, but the process requires additional steps and time
Solution Approach 1:
The message processing system is designed to handle multiple types of destination information inputs simultaneously. It can process voice messages, text messages, and direct speech inputs through a unified processing framework. This multi-functionality allows the system to extract destination data from various message formats without requiring separate processing procedures, thereby reducing the time and steps involved in acquiring destination information regardless of the message type.
Data Source
AI summary
A navigation system for an automotive vehicle capable of communicating with a remote communication device includes a host communication device connected to the remote communication device over a communication network to transmit voice data. A hands free communication unit having a speaker and a microphone is configured to connect with the host communication device so as to communicate with the remote communication device through the speaker and microphone. The vehicle navigation system also includes a voice recognition engine in communication with the hands free communication unit through a voice data link. A route generation unit is connected to the hands free communication unit and the voice recognition engine. The hands free communication unit is capable of transmitting the voice data originating from the remote communication device to the voice recognition engine over the voice data link. The voice recognition engine processes the voice data to extract a destination which is transferred to the route generation unit to determine a navigation route.
