    Hello

    I have a Spartan 3E XC3S500E FPGA starter kit and I'd like to implement a basic speech recognition system on it. My question is, How can I connect a microphone to this FPGA?
    The Spartan 3E starter kit contains an analog capture circuit consist of programmable pre amplifier (LTC6912-1 Dual Amp. and LTC1407A-1 Dual A/D) .
    Can these devices used to record speech signals with sufficient quality for speech recognition (e.g 5-10 KHz).
    I have the complete VHDL code to operate these devices, but i dont know a method to connect a mic to this circuit.
    I have an electert mic , Is this suite for this task or i must use another type.
    I will be very thankful for your help.
