Siri has been relegated to the confines of the iPhone 4S for the past six months, while many a new iPad owner and Mountain Lion beta tester have wondered what's taking Apple so long to release the feature from beta. For those of you running the latest version of OS X, Reddit user Moosehadley figured out that you can inject Siri's female voice right into OS X Lion (we've confirmed that this works for Mountain Lion as well.) All you need to do is go into System Preferences > Speech > Text to Speech. Use the System Voice pulldown, and choose Customize. From the list, select "Samantha" and let it install. This is the same voice used for Siri, and should hold you over until her full functionality makes it to the Mac.
