typical guitar pedal with just a mic plugged in it can create vocal effects, but effects that incorporate guitar require both a mic for the voice and a guitar to be plugged in. A vocoder works with two input signals: a carrier and a modulator. The modulator is typically the voice and its used to modulate the carrier signal, typically a synth but it could be your guitar. In short, via a complex process involving filters and VCAs, your vocal or speech characteristics are superimposed on the carrier signal, resulting in a talking synth (it has one built-in) or talking guitar.
