How can you write accessible button labels for screen readers?

1 Use plain and simple language

Screen readers usually read out the button label as it is written, without any context or interpretation. Therefore, you should use plain and simple language that is easy to understand and pronounce. Avoid jargon, abbreviations, symbols, or technical terms that might confuse or mislead the user. For example, instead of writing "CTA" or ">", write "Call to action" or "Next". Also, avoid using words that have multiple meanings or functions, such as "submit", "enter", or "go". Instead, use more specific and action-oriented words, such as "send", "confirm", or "search".

2 Indicate the button type and state

Screen readers also need to inform the user about the type and state of the button, such as whether it is a toggle, a radio, a checkbox, or a link. This helps the user to know what to expect and how to interact with the button. You can indicate the button type and state by using appropriate HTML attributes, such as role, aria-pressed, aria-checked, or aria-expanded. For example, if you have a button that expands or collapses a section of content, you can use the aria-expanded attribute to indicate whether the section is visible or hidden. You can also use the aria-label attribute to provide a more descriptive label for the button, such as "Show more details" or "Hide more details".

3 Provide feedback and confirmation

Screen readers also need to provide feedback and confirmation to the user after they click on a button. This helps the user to know that their action was successful and what happened next. You can provide feedback and confirmation by using sound effects, visual cues, or text messages. For example, if you have a button that submits a form, you can use a sound effect to indicate that the form was sent, a visual cue to show that the button is disabled, or a text message to thank the user and display the result. You can also use the aria-live attribute to announce dynamic changes in the content or state of the page, such as errors, warnings, or progress.

4 Test and optimize your button labels

Finally, you need to test and optimize your button labels for screen readers by using different devices, browsers, and screen reader software. This helps you to identify and fix any issues or inconsistencies that might affect the user experience and accessibility. You can also ask for feedback from real users who use screen readers, such as people with visual impairments, dyslexia, or cognitive disabilities. They can provide you with valuable insights and suggestions on how to improve your button labels and make them more accessible and user-friendly.
