Can Zumi hear me?

I learned that Zumi has 6 IR sensors, but does it have listening capability built-in or I have to plug-in additional modules? I wish I could program Zumi to do voice recognition.

@zommuter Whoops! I meant there is no microphone for voice recognition. There is a piezo buzzer

"no speaker" can't be correct considering the startup beep Depending on the wiring that one could potentially even be misused as a (very low-quality) microphone. Aside from that the GPIO Pins (https://www.raspberrypi.org/documentation/usage/gpio/) can (probably) be used for input if you add PWM between them and the Mic.

@victorzengyi There is no speaker on board and currently there is no way to attach one with the current setup. However, it should be possible to connect to the I2S pins on the Pi (not I2C) but we offer no support or documentation for that.
