iBook on iPad: turn pages with voice command I bought an iPad for somebody who is paralysed; primarily as a book reader for its ability to enlarge the text- but also to surf the net, etc. with a family member or caregiver using the touchpad. I want to know if there is a voice command so he is able to turn pages himself, rather than needing to rely on anyone else.
No - without some external hardware that would somehow touch the screen for you, voice input is for Siri / VoiceOver and not general accessibility controls.

You might look to a program like Instapaper where you can scroll the view by tilting the device but iBooks doesn't have any accelerometer based controls or voice controls at present. It's not that it couldn't be added, just that it hasn't.
