VoiceOver

VoiceOver is a screen reader built into macOS, iOS, iPadOS, tvOS, watchOS, and visionOS operating systems developed by Apple Inc. It provides auditory and braille feedback, enabling visually impaired users to interact with their devices.

Functionality:

VoiceOver reads aloud text displayed on the screen, describes interface elements like buttons and icons, and announces notifications and alerts. It can be controlled using a variety of gestures on touchscreens, keyboard commands, or braille displays. Users can navigate through the interface by item, group, or container, and adjust the speech rate, pitch, and volume to their preferences.

Accessibility Features:

VoiceOver offers a range of accessibility features designed to improve usability for visually impaired users, including:

• Speech: Converts text to speech in multiple languages and voices.
• Braille: Supports refreshable braille displays for output and input.
• Navigation: Provides various navigation methods for efficient screen exploration.
• Rotor: Allows quick access to commonly used settings like character, word, line, and container navigation.
• Verbosity Control: Enables customization of the amount of information announced.

Usage:

VoiceOver is activated and deactivated through system settings or by using Siri voice commands. Once enabled, it modifies the standard user interface to provide auditory and/or braille feedback. Developers can further optimize their applications for VoiceOver by using proper accessibility APIs and labeling user interface elements appropriately.
