JAWS Screen Reader Mispronunciation Of IQR Abbreviation Discussion

Introduction

The intersection of assistive technology and educational software presents unique challenges and opportunities. This article delves into a specific issue encountered with the JAWS screen reader when interpreting the abbreviation "IQR" (Interquartile Range) within the context of the PhET Interactive Simulations project, specifically the "Center and Variability" simulation. This seemingly minor issue highlights the importance of considering how screen readers interpret abbreviations and acronyms, especially in educational materials where clarity and accessibility are paramount. We'll explore the technical details of the problem, its potential impact on users, and discuss strategies for mitigating such issues in the future, ensuring that educational resources are accessible and inclusive for all learners.

Problem Description: The Unfortunate Pronunciation of IQR by JAWS

The core issue arises from how the JAWS (Job Access With Speech) screen reader vocalizes the abbreviation "IQR." Instead of pronouncing it as the individual letters "I-Q-R," JAWS attempts to read it as a single word. This misinterpretation leads to a pronunciation that sounds strikingly similar to an inappropriate word, creating a potentially embarrassing and distracting experience for the user. This issue was observed in the context of the "Center and Variability" simulation within the PhET Interactive Simulations project, specifically identified in GitHub issue #1268.

It is crucial to understand that this is not a flaw in the underlying mathematical concept of the interquartile range (IQR) itself, but rather a quirk in how the JAWS screen reader processes this particular abbreviation. The interquartile range is a fundamental statistical measure, representing the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. It provides valuable insight into the spread and variability of data, and is widely used in various fields, including statistics, data analysis, and machine learning. The unfortunate pronunciation by JAWS, therefore, poses a significant accessibility barrier, as it obscures the intended meaning and can lead to confusion and discomfort for visually impaired users.

The context in which this issue occurs further compounds the problem. Educational simulations like the "Center and Variability" simulation are designed to be engaging and interactive learning tools. When a screen reader misinterprets a key statistical term, it disrupts the learning process and can negatively impact the user's understanding of the material. The potential for misinterpretation is particularly concerning in educational settings, where students may be hesitant to ask for clarification due to embarrassment or fear of judgment. Therefore, addressing this issue is not merely a technical fix, but a crucial step in ensuring equitable access to educational resources.

Technical Details: Device, OS, Browser, and the Role of Screen Readers

The issue was specifically observed on a Samsung Laptop running Windows 11, using the Chrome browser in conjunction with the JAWS screen reader. This information is crucial for understanding the scope of the problem and identifying potential solutions. Screen readers, like JAWS, are essential assistive technologies that enable visually impaired individuals to access digital content. They work by converting text and other on-screen elements into synthesized speech or Braille output.

To effectively convey information, screen readers rely on a combination of techniques, including text-to-speech engines, semantic analysis, and predefined pronunciation rules. However, ambiguities can arise when dealing with abbreviations, acronyms, and specialized terminology. In the case of "IQR," JAWS's attempt to pronounce it as a single word highlights the limitations of its default pronunciation rules. While JAWS is a highly sophisticated screen reader, it cannot always accurately predict the intended pronunciation of every abbreviation, especially those that may have unintended phonetic consequences. This underscores the need for developers to be mindful of how screen readers interpret text and to implement strategies to ensure accurate and clear pronunciation.

The combination of the operating system, browser, and screen reader can also influence the behavior and performance of assistive technologies. Different browsers may render web content in slightly different ways, which can affect how a screen reader interprets the text. Similarly, the operating system's accessibility settings and the screen reader's configuration can impact the final output. Therefore, thorough testing across various platforms and configurations is essential to ensure accessibility for all users. In this particular case, the combination of Windows 11, Chrome, and JAWS exposed the pronunciation issue with "IQR," highlighting the importance of comprehensive accessibility testing.

Impact on Users: Embarrassment, Confusion, and Barriers to Learning

The impact of this seemingly small pronunciation error can be significant for users, particularly in an educational context. The unfortunate pronunciation of "IQR" can lead to embarrassment and discomfort, potentially discouraging students from asking questions or participating in class discussions. This is especially problematic for students who are already navigating the challenges of visual impairment and may be more sensitive to social stigmas associated with assistive technology.

Beyond the emotional impact, the mispronunciation can also create confusion and hinder understanding of the statistical concept of the interquartile range. If a student mishears the term, they may struggle to grasp its meaning and application. This can have a ripple effect on their learning, as the IQR is a fundamental concept used in various statistical analyses and data interpretations. A lack of clarity on this concept can impede their progress in the subject and limit their ability to engage with more advanced statistical topics.

This issue underscores the critical role of accessibility in education. When educational materials are not fully accessible, they create barriers to learning for students with disabilities. In this case, the mispronunciation of "IQR" by JAWS acts as an unintentional barrier, preventing visually impaired students from accessing and understanding the intended information. This highlights the need for developers and educators to prioritize accessibility in the design and implementation of educational resources. By addressing these issues proactively, we can create a more inclusive learning environment for all students.

Mitigation Strategies: Ensuring Accurate Pronunciation in Screen Readers

Several strategies can be employed to mitigate the issue of JAWS mispronouncing "IQR" and similar abbreviations. These strategies fall into two main categories: technical solutions within the software and best practices for content creation.

Technical Solutions within the Software

1. Custom Pronunciation Dictionaries: JAWS and other screen readers allow users to create custom pronunciation dictionaries. These dictionaries enable users to define how specific words or abbreviations should be pronounced. For "IQR," a user could add an entry that explicitly spells out the letters "I-Q-R" instead of attempting to pronounce it as a single word. This is a user-side solution, empowering individuals to tailor the screen reader to their specific needs.
2. ARIA Attributes: ARIA (Accessible Rich Internet Applications) attributes provide a way to add semantic information to HTML elements, making them more accessible to assistive technologies. The aria-label attribute can be used to provide an alternative text label for an element, which the screen reader will use instead of the element's displayed text. In this case, `aria-label=
