Screen Reader Plugin

A small piece of code that extends or modifies the functionality of a screen reader application. Screen reader plugins can make inaccessible applications accessible, customize the screen reader's behavior for specific software, add new keyboard shortcuts, and provide additional audio feedback. Plugins are developed using screen reader-specific APIs — for example, NVDA uses Python-based add-ons while JAWS uses its own scripting language. The plugin ecosystem faces challenges including the lack of centralized repositories for most screen readers, poor documentation, minimal maintenance after initial release, and security risks from unvetted distribution channels.
