    I'm not sure, but I doubt it.
    You need advice from someone who is familiar with this topic.

    Microchip actually has speech recognition software for the dsPIC chips, so it is quite possible.

    Interfacing a microphone is done through an opamp preamp that amplifies it and offsets it by 1/2 Vdd then using the built in ADC.
