Vehicle Interface Translation Using Audio-Video Speech Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between a vehicle occupant and another individual, whether inside or outside the vehicle, is hindered by language barriers and environmental factors, which existing systems fail to effectively address.
Innovation Solution
A vehicle communication system comprising a microphone, camera, and output device, connected to a computer that generates text from audio and video data, translates languages, and directs the output to ensure effective communication across language barriers and environmental interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle occupant attempts to communicate with another individual, then communication is desired, but language barriers and environmental factors impair or prevent effective communication
Solution Approach 1:
The patent introduces a translation system as an intermediary between speakers of different languages. The system captures audio from the first language speaker, translates it to the second language, and outputs the translated speech, thereby mediating the communication barrier. This directly addresses the language barrier harmful factor by inserting a translation intermediary in the communication path.
Solution Approach 2:
The patent replaces the natural human communication mechanism (direct speech) with a technological system involving microphones, processors, translation algorithms, and speakers. This substitution allows the system to overcome environmental factors and language barriers that would naturally impede direct human communication.
2Productivity
If audio-based text generation is used, then speech-to-text conversion is achieved, but accuracy is reduced without video supervision
Solution Approach 1:
The patent merges audio-based text generation with video-based text generation into a unified system. The audio microphone captures speech and generates text, while the video camera captures lip movements and generates text. These two text generation streams are then combined and compared to produce a final, more accurate transcription, thereby merging the advantages of both modalities.
Solution Approach 2:
The system uses video feedback to supervise and verify audio-based text generation. The video camera continuously monitors lip movements, and this visual information is fed back into the text generation process to correct or confirm the audio-based transcription, improving accuracy through continuous feedback validation.
3Measurement precision
If multiple text generation methods are combined, then accuracy is improved, but system complexity increases
Solution Approach 1:
The patent creates a universal text generation system that can process both audio and video inputs through a common architecture. The system uses a single processor that handles both audio-based and video-based text generation, along with a unified combination logic that merges the results. This multi-functional approach achieves high accuracy while avoiding the need for separate independent systems.

AI summary
An audio system for a vehicle includes a microphone focused on a first designated location of a first person with respect to the vehicle, a camera with a field of view encompassing the first designated location, an output device directed to a second designated location of a second person with respect to the vehicle, and a computer communicatively coupled to the microphone, the camera, and the output device. The computer is programmed to generate first text in a first language based on input audio data from the microphone and video data from the camera, translate the first text to second text in a second language, and instruct the output device to output the second text.
