The exercises I've suggested for others applies universally, I reckon. 1) Oral communication: Advertise your office/skype/mobile phone number in your sig or any comms with colleagues. Then solicit them to phone you for any reason. You will get calls. Then talk to them instead of letting it go to voicemail. 2) Written: Prefer e-mail over twitter/sms/irc. Never write one word or sentence rattles unless it is a response in kind. If someone has written a thoughtfully written, detailled and professional email to you, return the favor. 3) When it is more convenient to fire off a quick email or text to someone sitting across the hall, get up and go talk to them instead. This is even more important if you don't know them personally. Introduce yourself, engage in conversation. 4) Nerves are for the nervous. If you aren't nervous in front of friends, relatives, or complete strangers at the grocery store, you shouldn't be nervous in front of your colleagues or bosses. They cut and bleed just as readily as the rest of those you know.
