Text Recitation Tracking via Audio Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices struggle to consistently track the recitation of text, as the scroll rate often diverges from the reader's pace, and users face difficulties in re-locating their position when distracted, especially when reading aloud.
Innovation Solution
An apparatus comprising a processor and memory that displays text segments, receives audio signals, and indicates the corresponding position in the text based on word similarity, allowing for dynamic adjustment of the scroll rate and highlighting to maintain synchronization with the reader's pace.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the computing device scrolls text at a given rate, then the text display is automated, but the scroll rate may not be consistent with the reader's pace
Solution Approach 1:
The patent implements dynamic scroll rate adjustment by detecting user interactions (clicks, scrolls) and automatically modifying the scroll speed to match reader pace. The system transitions from a static predetermined scroll rate to a dynamic rate that adapts in real-time based on user behavior, resolving the contradiction between automation and adaptability.
Solution Approach 2:
The system incorporates feedback mechanisms by monitoring user actions such as manual scrolling and clicking behaviors. This feedback is used to adjust the automated scroll rate, creating a closed-loop control system that ensures the scroll pace remains consistent with the reader's preferences without requiring explicit configuration.
2Productivity
If the scroll rate is increased to improve reading efficiency, then more text is displayed, but the scroll rate may get ahead of the reader
Solution Approach 1:
The system uses real-time feedback from user interactions (lack of scrolling, clicking on previous text) to detect when the scroll rate exceeds reader comprehension speed. This triggers automatic deceleration or pausing of the scroll, maintaining synchronization reliability while preserving high reading efficiency during normal operation.
Solution Approach 2:
The system proactively prevents desynchronization by monitoring reading pace and applying counter-actions (slowing down or pausing scrolling) before the scroll gets significantly ahead of the reader, thereby maintaining reliability without reducing overall productivity.
3Ease of operation
If the reader looks away from the display, then distraction is unavoidable, but it becomes difficult to find the position after return
Solution Approach 1:
The patent employs visual highlighting (color changes) to mark the current reading position and previously viewed text segments. When the reader returns after looking away, the highlighted indicators provide immediate visual cues for quick position re-location, reducing both the effort and time required to resume reading.
Solution Approach 2:
The system prepares position markers and visual indicators in advance during normal reading, so that when the reader needs to re-locate after distraction, the information is already available and clearly marked, eliminating the need for time-consuming search actions.
4Ease of operation
If manual configuration of read rate is required, then precise control is achieved, but the operation becomes complex
Solution Approach 1:
The system performs self-service by automatically determining the optimal scroll rate based on user interaction patterns without requiring manual configuration. The reader simply engages with the text naturally, and the system infers and adjusts the read rate accordingly, achieving both ease of operation and precise control through adaptive algorithms.

AI summary
For tracking a recitation of text, a method is disclosed that includes displaying, by use of a processor, a segment of text, receiving an audio signal, and indicating a position in the segment of text determined by a correspondence between the audio signal and the segment of text.
