Aircraft
Due to smoke in cockpit at cruise we requested priority handling; ran smoke in cockpit checklist and memory items; landed safely. After landing I determined we were not in a fully developed active fire; so elected with the escort of the ARFF vehicles to head to a gate; deplaned without incident; fully shut down the plane.  Potential fire from avionics or pack system.Suggestions - Improve the o2 mask microphone and reduce o2 noise in the system so that it is easier to hear your crew and ATC.
EMB-145 Captain reported diverting to a nearby airport due to smoke in the cockpit. The reporter also reported difficulty in communicating with the oxygen mask on.
