Spoken Content is a built-in feature in macOS that allows users to have text read aloud. You can find this function within the Accessibility settings. One of the key options under Spoken Content is Speak Selection, which enables you to have text from any application, whether written by you or found in a web browser, read aloud.

For detailed instructions on how to use Spoken Content, visit Apple’s official support guide:

Note: The default key combination to activate Speak Selection is Option + ESC. To view or change this shortcut, click the information icon (ⓘ) next to the enabling switch within the Spoken Content settings.
