Language-Proficiency Content Replay With Timed Text and Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for assisting language learning through closed captions and subtitles do not account for the user's proficiency level, leading to difficulties in reading and understanding content, particularly for those with low proficiency, resulting in stagnation or loss of interest.
Innovation Solution
A system that detects a user's language proficiency level and adjusts the content playback, including timed text rendering, audio language, and playback speed, to accommodate the user's proficiency, offering features like split-screen display and metadata for improved learning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If timed text is displayed to provide full context of the scene, then the user can understand the content, but the user with low proficiency cannot read it within the scene duration
Solution Approach 1:
The system dynamically adjusts playback speed based on user proficiency level. For low-proficiency users, the playback speed is slowed down when timed text is displayed, allowing sufficient reading time while maintaining full context. This dynamic adjustment resolves the contradiction between providing complete information and allowing adequate processing time.
Solution Approach 2:
The system changes the timing parameters of timed text display based on user proficiency. For low-proficiency users, the display duration of each timed text is extended beyond the original scene duration, and playback speed is reduced. This parameter modification enables users to read and understand the full context without rushing.
2Productivity
If the content is played back at normal speed, then the scene progresses smoothly, but the user with low proficiency cannot read and understand the timed text
Solution Approach 1:
The system implements dynamic playback speed adjustment based on user proficiency level. For low-proficiency users, playback speed is automatically reduced during timed text display portions, making reading easier while maintaining overall content consumption efficiency. This dynamic adaptation resolves the contradiction between speed and readability.
3Loss of information
If the user rewinds and replays the scene to re-read the timed text, then the user can understand the content, but the user loses interest and stagnates in learning
Solution Approach 1:
The system performs preliminary adaptation of the content by pre-adjusting playback speed and timed text display duration based on user proficiency level before playback begins. This preliminary action ensures that low-proficiency users can read and understand timed text during the first playback without needing to rewind, eliminating repetitive viewing and maintaining learning momentum.
Solution Approach 2:
The system uses user proficiency level as feedback to automatically adjust content delivery parameters. By detecting user proficiency and相应地 adjusting playback speed and timed text timing, the system creates a feedback loop that adapts to user needs, preventing the need for manual rewinding and keeping users engaged in their learning journey.
4Loss of information
If the timed text is synchronized to the scene, then the context is clear, but the user cannot read the text before the scene changes
Solution Approach 1:
The system modifies the timing parameters of timed text display based on user proficiency level. For low-proficiency users, the display duration is extended beyond the original scene boundaries, and playback speed is reduced. This parameter change ensures that users have sufficient time to read the text while maintaining context clarity through synchronized display.

AI summary
Systems and methods for replaying a portion of a content item based on the user's language proficiency level in a secondary language is disclosed. The system accesses a user profile comprising a user's proficiency level in at least one secondary language, the secondary language being their non-native language. A command to replay a first portion of a content item is received and, in response to receiving the replay command, the system generates for display the first portion of the content item at a level below the user's proficiency level in the secondary language.
