Vehicle Emergency Call Speech-to-Text for Helmet Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency call systems for vehicles without enclosed cabins, such as motorcycles and bicycles, face challenges in verbal communication due to helmet usage and ambient noise, impairing speech reception and instruction comprehension.
Innovation Solution
Converting spoken help instructions into textual information displayed on a vehicle-mounted display and optionally playing them via a loudspeaker, with the option to record and transmit a voice message to the control center, and providing a speech-to-text conversion module to adapt instructions based on vehicle type and user language preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If spoken help instructions are transmitted to vehicle users, then communication of assistance information is enabled, but comprehensibility and perception are impaired due to helmet usage and ambient noise
Solution Approach 1:
The patent introduces a speech-to-text conversion module as an intermediary that transforms spoken help instructions into text format. This intermediary component bridges the communication gap caused by helmets and noise, allowing vehicle users to read assistance information textually rather than relying on auditory communication that is blocked by helmets and ambient noise.
Solution Approach 2:
The patent replaces the acoustic communication mechanism (spoken instructions through loudspeaker) with a visual/text-based mechanism (text display). This substitution eliminates the dependence on sound transmission that is impaired by helmets and ambient noise, providing a reliable alternative communication channel for emergency assistance information.
2Adaptability or versatility
If speech-to-text conversion is implemented in each vehicle, then language adaptation is improved, but infrastructure costs increase significantly
Solution Approach 1:
The patent merges the speech-to-text conversion functionality into the centralized control center rather than distributing it across multiple vehicles. By combining this resource-intensive function at a single location, the system achieves language adaptation capability while avoiding the cost multiplication that would result from implementing conversion modules in every vehicle.
Solution Approach 2:
The control center is designed to serve multiple vehicles simultaneously with a single speech-to-text conversion module. This universal approach allows the same infrastructure to support language adaptation for numerous vehicle users, eliminating the need for duplicate conversion systems in each vehicle and significantly reducing overall infrastructure costs.
