What type of errors are read by screen readers according to error message accessibility features?

Screen readers are designed to enhance accessibility for users by reading aloud the content of web pages, including error messages that are presented during user interaction with forms. When it comes to identifying errors, field level errors are particularly important because they provide immediate feedback about specific form inputs.

Field level errors relate directly to an individual input field, indicating when a user's input does not meet validation criteria. This can include issues such as missing required fields, incorrect formats (like a phone number or email address), or data that falls outside specified limits (such as a number being too high or too low). By communicating these specific errors, screen readers help users to identify what they need to correct, facilitating a better overall experience for those relying on assistive technology.

In the context of the other choices, options focusing on only syntax-based errors or broader categories like all user-input related errors may not reflect the specificity of feedback needed. While syntax errors can be part of user-input errors, they do not encompass all types of feedback provided within an accessible UI. Additionally, the notion that no errors are usually read contradicts the principles of accessibility, where it's vital for users to be aware of any issues that could impact their ability to complete a form successfully.
