On Mavericks, I have Voiceover turned off in both Accessibility settings and Users & Groups.
In the past week, Voiceover has started occasionally reading small bits of text to me, seemingly unrequested.
It seems to primarily be subject lines of new mail in Gmail (running as a webpage in Chrome), but this could be a red herring.
Is there a keyboard shortcut or trackpad gesture that I'm accidentally doing to make this happen? What could be going on?
[Update: see comments - I'm now certain it's only emails that are getting read aloud, but not sure whether it's anything to do with Chrome or not. OS-level email integration?]
