From what you have described here I dont think this is the wiper switch/control at fault for the wiper issue since the wipers will not park like they should,this sounds more like the wiper motor/control board itself at fault as this will cause no operation when in intermittent as well as not allowing the wipers to park properly.Usually this is the cause here on models that use a circuit board/control panel to control the wipers.It is possible the wiper switch/control is at fault but this sounds more like the control panel for the motor itself.This will have to be tested further to be sure and may require a computer to be plugged into your vehicle (one that is compatible with this model) to check signals for the wiper control to be sure of the component needing replaced.
The second issue sounds like a fault in either the voice control switch wiring being shorted causing this to occur intermittently with the voice control or a fault in the head unit itself.The wiring will need checked leading from the control switch for voice control operation to see if any wiring needs repaired.If found to be o.k. I suspect the head unit/radio may need repaired or replaced but this would need to be tested further as well to be sure.
