Webpage Accessibility Compliance via Audio Transcript Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for evaluating webpage accessibility compliance are inefficient and inaccurate, as they primarily focus on reviewing underlying HTML code without considering the actual user experience, potentially leading to non-accessible webpages being made public.
Innovation Solution
A computer-implemented method that displays a compliant initial version of a webpage, modifies it to create a second version, initiates a voiceover using automatic text-to-speech software, records and stores the voiceover, and generates a textual transcript to determine compliance with accessibility rules by comparing the transcript to the initial version and rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional code review techniques are used to evaluate webpage accessibility compliance, then the evaluation process is simple and quick, but the accuracy and reliability of compliance determination deteriorates
Solution Approach 1:
The patent creates a voiceover copy of the webpage content using text-to-speech software, then records and transcribes it to text. This textual copy of the audio output is then analyzed for accessibility compliance. This copying approach allows evaluation of the actual rendered content experience rather than just reviewing source code, thereby improving accuracy while maintaining automated efficiency.
2Productivity
If only HTML code is reviewed for accessibility compliance, then the evaluation process is efficient, but the ability to detect actual accessibility issues deteriorates
Solution Approach 1:
The patent replaces the mechanical code review process with an audio-based evaluation system. Text-to-speech software converts webpage content to speech, which is then recorded and transcribed. This substitution allows the system to evaluate the actual auditory experience of screen reader users rather than merely checking code structure, thereby improving reliability while maintaining automated efficiency.
3Measurement precision
If a voiceover recording and transcription process is implemented for compliance evaluation, then the accuracy of accessibility determination improves, but the complexity of the evaluation process increases
Solution Approach 1:
The patent employs text-to-speech software that can process various types of webpage content (text, headings, lists, etc.) through a single unified voiceover generation process. The recorded voiceover is then transcribed to text and analyzed using automated tools. This multi-functional approach handles diverse webpage elements through one standardized process, improving accuracy without proportionally increasing complexity.
4Reliability
If automated text-to-speech software is used to generate voiceovers for compliance testing, then the ability to simulate actual user experience improves, but the time required for evaluation increases
Solution Approach 1:
The patent performs preliminary actions by generating the voiceover recording and transcription before the actual compliance analysis. The text-to-speech software converts all webpage content to speech in advance, and the recording is transcribed to text beforehand. This preliminary preparation allows the subsequent compliance checking to focus only on analyzing the pre-generated transcript, thereby reducing the overall evaluation time while maintaining high user experience simulation accuracy.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method provides a more accurate and reliable evaluation of webpage accessibility compliance, ensuring that modified webpages meet accessibility standards by simulating the user experience and identifying non-compliant portions.
Implementation Method 1
starting automatic text-to-speech software that reads aloud the second version of the webpage
Implementation Method 2
The voiceover of the second version of the webpage may be recorded and stored
Implementation Method 3
A textual transcript of the stored recording of the voiceover of the second version of the webpage may be generated
Data Source
AI summary
Aspects described herein may provide determination of compliance with accessibility rules by a webpage. A first version of a webpage may be compliant with the accessibility rules. The first version of the webpage may be modified to create the second version of the webpage. The second version of the webpage may be displayed. A voiceover of the second version of the webpage may be initiated. The voiceover may include starting automatic text-to-speech software that reads aloud the second version of the webpage. The voiceover of the second version of the webpage may be recorded and stored. A textual transcript of the stored recording may be generated. Compliance of the second version of the webpage with the accessibility rules may be determined based on the textual transcript of the stored recording and based on the first version of the webpage.
