This is an annoying bug - but in Apple's defense - it's only been open for 10 months and only affects more than TWENTY THOUSAND developers that are watching this exact ticket. (rolling eyes) Seriously though... I can't fathom the reason why Apple does not make this issue a priority to fix. I think that somebody in support or development at a fairly low level is ignoring (or actively blocking) the escalation of this problem for some misguided reason and I can only hope that they get fired for their incompetence when this issue finally gets the attention of somebody competent in management.

Did you ever get an answer to this? I want to deep link to Settings->Accessibility->Personal Voice so the user can toggle it on for my app. The closest I'm able to get so far is to "Settings->MyApp Settings".

Never mind. I appear to have been mistaken. The list of voices that is returned by speechVoices() only includes voices that are actually downloaded and available. I'm not sure what led me to believe otherwise. However, this does lead to a slightly different question: Is there a way to get a list of voices that are available to be downloaded - but have NOT been? And to know what quality options are available for download? I would like my app to be able to determine when Apple makes new "Premium" voices available so I can notify my users.
