Automotive Speech Interface Hybrid Announcement Engine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive processing systems lack the capability to seamlessly integrate navigation and touring announcements, leading to fragmented information delivery to the vehicle operator.
Innovation Solution
An automotive processing unit integrated with a speech interface that combines navigation and touring announcements to create hybrid announcements, utilizing a natural-language engine to insert content from one announcement into the other, and delivering these announcements through a loudspeaker in the vehicle cabin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation and touring announcements are delivered separately, then each announcement can be delivered independently and simply, but the information delivery becomes fragmented and less cohesive
Solution Approach 1:
The patent merges navigation announcements and touring announcements into a single hybrid announcement delivered through the speech interface. The natural-language engine combines content from both announcement types, inserting touring information at appropriate points within navigation instructions, creating a unified information delivery that prevents fragmentation while maintaining operational simplicity.
2Loss of information
If touring announcements are inserted frequently into navigation announcements, then touring information is delivered more often, but the cognitive load on the operator increases
Solution Approach 1:
The system applies partial action by selectively inserting touring announcements only at appropriate points within navigation announcements rather than continuously. The natural-language engine identifies suitable insertion points based on the grammatical structure and content of navigation instructions, delivering touring information sufficiently often to maintain engagement while avoiding excessive frequency that would overwhelm the operator's cognitive capacity.
3Loss of information
If the speech interface combines all announcement content, then a comprehensive hybrid announcement is created, but the announcement duration increases
Solution Approach 1:
The patent segments the hybrid announcement by inserting touring information as concise interruptions within navigation instructions rather than appending all touring content separately. The natural-language engine divides the touring announcement into discrete information elements that are strategically placed at grammatical boundaries and natural pause points within the navigation flow, maintaining information completeness while preventing excessive overall duration.

AI summary
An automotive processing unit includes an infotainment system having a speech interface, an application suite comprising one or more spatially-cognizant applications, and an automotive assistant that is configured to execute one or more of the spatially-cognizant applications. The speech interface is configured to receive a navigation announcement from a navigator and a touring announcement from one of the spatially-cognizant applications and, in response, to cause a spoken announcement to be made audible in a vehicle's cabin through a loudspeaker. The spoken announcement comprising content from at least one of the touring announcement and the navigation announcement.
