Page Loading, Web category, VoiceOver Utility on Mac
Use the Page Loading pane of the Web category in VoiceOver Utility to specify what happens when a web page opens.
To open VoiceOver Utility, press Command-F5 to turn VoiceOver on, then press VO-F8.
Note: VO represents the VoiceOver modifier.
Speak web page summary
When a web page opens, have VoiceOver speak a summary of the items on the page. The summary is based on the items selected in the Web Rotor pane of the Web category in VoiceOver Utility.
For example, if the Rotor includes headers, links, auto web spots and form controls, the web page summary that VoiceOver speaks might sound like “The Apple - Accessibility page has 14 headers 52 links 8 auto web spots 1 form control”.
Automatically speak the web page
When a web page opens, have VoiceOver start reading the page. If you set a sweet spot on the page, VoiceOver starts reading from the sweet spot; otherwise, it starts reading from the beginning of the page.
This option is available only if you select the previous option to move the VoiceOver cursor to the first item or sweet spot.
While a web page loads
Click the pop-up menu, then choose what you want to hear while a web page is being displayed: Speak Progress, Play Tone or Do Nothing.
By default, VoiceOver speaks the percentage of the web page that is loaded.
