Vehicle Voice Message Control With Keyword Emphasis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle message output systems often use fixed utterance rates and intonation, making it difficult to quickly deliver critical information and identify keywords, especially in situations requiring quick guidance.
Innovation Solution
An apparatus and method for controlling vehicle message output that allows for varying utterance speeds, emphasizing keywords, and adjusting intonation based on user input, including classification of message sections and repetition of keywords.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fixed utterance rate is used for message output, then the message delivery is consistent and stable, but the critical information cannot be delivered quickly enough
Solution Approach 1:
The message is divided into multiple sections with different importance levels. Critical information sections are identified and separated from general information sections, allowing different utterance speeds to be applied to different segments while maintaining overall message coherence.
Solution Approach 2:
Different utterance speeds are applied to different sections of the message based on their importance. Critical information sections are delivered at faster speeds while maintaining stability in less critical sections, achieving both speed improvement and consistency where needed.
2Reliability
If similar words are repeatedly used for accurate message delivery, then the message accuracy is improved, but the keywords become difficult to identify
Solution Approach 1:
Different intonation patterns and pitch variations are applied to different sections of the message, similar to using different colors for emphasis. Keywords and critical information are delivered with distinct intonation characteristics that make them easily identifiable against the background of other message content.
3Ease of operation
If the same intonation is used for all messages, then the message delivery is uniform and simple to process, but the critical information cannot be emphasized
Solution Approach 1:
Different intonation patterns are applied to different sections of the message based on their importance. Critical information sections receive distinctive intonation treatment while other sections use standard intonation, maintaining simplicity where appropriate while providing emphasis where needed.
4Loss of time
If the message is delivered quickly, then the response time is reduced, but the user may not have time to understand and process the information
Solution Approach 1:
The message is segmented into critical and non-critical sections. Critical information is delivered first at a faster pace, followed by less critical information, allowing the user to grasp the most important points quickly while still receiving complete information if time permits.
Solution Approach 2:
Distinctive intonation patterns are used to highlight critical information, allowing users to quickly identify and process important points even when listening at faster speeds. The varied intonation acts as an auditory marker for information priority.

AI summary
An apparatus and method for controlling a vehicle message output. The apparatus includes an input device that receives an input of a user, and a processor that generates a guide message and controls the guide message to be output by applying an emphasis scheme set by the input of the user to a keyword when determining that the keyword exists in the guide message.
