Edge Device Alternative Audio Captioning Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Closed captioning text often contains transcription and translation errors, and may not accurately reflect the audio due to synchronization issues, making it less useful for viewers. Additionally, closed captioning text and audio may not be available in all languages, limiting accessibility for viewers who prefer to watch in their native language.
Innovation Solution
The system generates alternative closed captioning text and/or alternative audio based on content received by an edge device, using speech recognition and machine learning models to transcribe and translate audio into different languages, and to synchronize the captions accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If closed captioning text is provided for audio content, then accessibility for viewers is improved, but accuracy of the closed captioning text deteriorates due to transcription and translation errors
Solution Approach 1:
The system creates alternative closed captioning text by transcribing audio content and translating it, effectively copying the audio information into text form. This allows viewers to access content in their preferred language while maintaining accuracy through automated transcription and translation processes that can be updated and refined.
Solution Approach 2:
The system changes the language parameter of the closed captioning text to match the user's preferred language, even when the original audio is in a different language. This enables accessibility for viewers who want to watch content in their native language by translating the audio track or providing accurate subtitles in their preferred language.
2Ease of operation
If closed captioning text is synchronized with audio content, then viewing experience is improved, but synchronization accuracy deteriorates due to timing differences in receiving caption and audio data
Solution Approach 1:
The system performs preliminary synchronization by adjusting the timing of closed captioning text to match the audio content before presentation to the user. This preliminary action ensures that even when caption and audio data are received at different times, the final output is accurately synchronized for optimal viewing experience.
Solution Approach 2:
The system uses feedback mechanisms to continuously monitor and adjust the synchronization between audio content and closed captioning text. By detecting timing differences and making real-time adjustments, the system maintains accurate synchronization despite variations in data reception timing.
3Adaptability or versatility
If alternative audio content in different languages is provided, then language accessibility is improved, but device complexity increases due to speech recognition and translation processing
Solution Approach 1:
The system introduces an intermediary processing layer that handles speech recognition and translation tasks. This intermediary component, which could be a cloud service or specialized module, processes the audio content and generates alternative language versions, reducing the complexity burden on the main device while enabling multi-language accessibility.
Solution Approach 2:
The system implements a universal processing approach that can handle multiple languages and content types through a single integrated framework. The same speech recognition and translation mechanisms work across different languages and content sources, improving language accessibility without proportionally increasing device complexity.
Data Source
AI summary
Systems, apparatuses, and methods are described for receiving content and closed captioning text based on audio in the content. Alternative closed captioning text and/or alternative audio may be generated based on a translation of the content. Voice characteristics of recognized speech may be used in the generation of alternative closed captioning text and/or alternative audio. Further, the alternative closed captioning text and/or alternative audio may be outputted in place of the original closed captioning text and/or audio.
