ios, turn on VoiceOver programmatically

Question

I'm building an app that will run in kiosk mode as part of an instillation with the home button covered.

I would like to give the user the ability to turn VoiceOver on if required.

Is it possible to do this programmatically?

Edit for clarification

I don't wish to just turn on the voice synthesizer, rather I would like to turn on all the features that are enabled with enabling of the VoiceOver accessibility option, this includes changing the way that touch events are reacted to.

Answer 1

I don't believe it's possible to turn VoiceOver on programatically.
