Vehicle Speech Interface Session Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current speech interfaces in vehicles and cellular devices are limited in their ability to provide a fully hands-free experience, as they often require physical interaction with the device and do not support broad access to various Internet-based and computer-based services available on mobile devices.
Innovation Solution
A method that enables hands-free communication between a vehicle occupant and their mobile device by using a mobile voice platform, which includes a speech platform kernel and an application interface suite, allowing for wireless interaction with cloud services and installed applications, and prioritizes speech sessions to manage multiple service requests effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech-based HMI systems use application-specific command sets with syntactically constrained interactions, then the system can convert inputted speech into specific commands for specific applications, but the ability to identify and carry out different services involving different applications or service providers is limited
Solution Approach 1:
The patent implements a universal speech interface that can handle multiple applications and services through a common architecture. The system uses a unified speech recognition framework that can identify and route speech inputs to various services (messaging, navigation, media control, etc.) without requiring application-specific command sets, thereby achieving both ease of operation and adaptability
2Ease of operation
If embedded cellular phones are used with access to vehicle electronics for hands-free telephony and basic vehicle control, then driver distraction is reduced, but access to many other built-in and user added applications and functions is not provided
Solution Approach 1:
The system extends hands-free capability from basic telephony to access all vehicle and mobile device applications. The speech interface is designed to universally control infotainment, navigation, messaging, and user-added applications, transforming the embedded phone from a single-function device to a multi-functional control system
3Ease of operation
If personal mobile devices are used with basic audio interface and Bluetooth connection for speech and audio transmission, then speech communication is enabled, but only a few basic mobile device functions such as calling and controlling music selection and playback are supported
Solution Approach 1:
The patent creates a universal bridge between the vehicle audio interface and the mobile device that enables speech-based control of all mobile device functions, not just basic calling and media control. The system routes speech commands to appropriate mobile device applications, enabling hands-free access to messaging, navigation, and user-added applications
4Adaptability or versatility
If commercially-available systems with built-in speech support are used, then greater integration is provided, but a fully hands-free experience is not achieved since they still rely heavily on the screen to interact with the user during the speech session
Solution Approach 1:
The patent extracts the speech recognition and processing functionality from the mobile device screen interface and relocates it to the vehicle's audio system. By separating the speech interface from the visual display, the system enables truly hands-free operation while maintaining integration with mobile device applications, removing the dependency on screen interaction

AI summary
A method of managing speech interfaces to computer-based services includes beginning a first speech session that is carried out in a vehicle over a short-range wireless connection between a vehicle occupant and a mobile device; detecting an initiation of a second speech session while the first speech session is being carried out; determining an assigned priority level of the first speech session relative to an assigned priority level of the second speech session based on a first speech context identified in the first speech session and a second speech context identified in the second speech session; and when the assigned priority level of the second speech session has a higher priority than the assigned priority level of the first speech session, carrying out a session-appropriate action on the first speech session.
