Reading Fluency Assessment Using Elapsed Time Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reading software primarily focuses on reading skills other than reading fluency and lacks effective methods to develop rapid and correct recognition and pronunciation of words, which are crucial for improving reading fluency.
Innovation Solution
A computer-based method that uses automatic speech recognition to assess reading fluency by measuring the elapsed time for word recognition and generating visual and audio interventions when thresholds are exceeded, providing feedback to users on their reading pace and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reading software focuses on reading skills other than fluency, then other reading skills are improved, but reading fluency development is neglected
Solution Approach 1:
The patent segments reading assessment into distinct components: word recognition accuracy, pronunciation correctness, and reading fluency (measured by elapsed time). This segmentation allows the system to specifically target and measure fluency separately from other reading skills, resolving the contradiction by enabling focused fluency development while maintaining comprehensive skill coverage
Solution Approach 2:
The system implements continuous feedback mechanisms that provide real-time monitoring of reading fluency metrics. By measuring elapsed time for word recognition and providing immediate feedback when thresholds are exceeded, the system actively develops fluency while maintaining broad reading skill assessment
2Reliability
If the system provides immediate visual and audio interventions for every threshold exceedance, then reading fluency improvement is maximized, but system complexity increases
Solution Approach 1:
The patent applies different intervention qualities to different situations: visual interventions (highlighting, underlining, coloring) are applied for minor threshold exceedances, while audio interventions (pronunciation guidance, re-reading instructions) are applied for more significant deviations. This localized differentiation of intervention types provides comprehensive fluency support without requiring a single complex intervention mechanism for all cases
Solution Approach 2:
The system dynamically adjusts intervention types and thresholds based on user performance patterns. Thresholds can be modified based on timing gaps, word position in sentences, and proximity to punctuation, allowing the system to adapt its complexity to actual user needs rather than applying fixed complex rules universally
3Measurement precision
If multiple timing thresholds are used for different intervention types, then reading fluency assessment precision is improved, but measurement complexity increases
Solution Approach 1:
The patent employs multiple timing parameters (first threshold for visual intervention, second threshold for audio intervention, third threshold for deferred visual indicium) to capture different aspects of reading fluency. Each threshold serves a specific measurement purpose, and the system manages this parameter complexity through systematic comparison logic that determines which threshold has been exceeded, providing precise measurement without overwhelming complexity

AI summary
A computer based method and related system, computer program product and device includes receiving audio input associated with a user reading a sequence of words and determining an approximate amount of time corresponding to an absence of input associated with an assessed word, after receiving audio input associated with a preceding word in the sequence of words, or since the start of the audio buffer or file. The method can also include displaying a visual indication or generating an audio intervention based on the determined amount of time corresponding to an absence of input.
