I'm planning to program my EV3 robot to do voice chat over VOIP using ev3dev and a Debian program. Is this possible? Are there microphones known to work with EV3, and has anyone had experience using them?

The number of devices that have been tested and documented is extremely limited, but at least one has been confirmed to work. The non-bluetooth solutions that have been tested successfully are the following.

I haven't heard of anyone using a microphone yet, but you have a couple of options. 1) a USB sound card/microphone or 2) Bluetooth headset/hands-free device.
The built-in speaker uses an alsa sound driver, so theoretically, it should work with any linux program.
If you are looking at purchasing something USB, make sure it does not require USB 2.0. The USB port on the EV3 is USB 1.1 only.
