I want to recognize the voice using raspberry pi and for that required a microphone

but most of the cases I have seen that USB microphone used in Raspberrypi for voice input, but I want to use a normal two-wire capsule microphone to provide voice input for recognition of the voice. So I need help on this, Please suggest me how to interface a normal capsule microphone with raspberry pi for voice input to recognize the voice.

Thanks,

I believe there is no audio input on the Raspberry 3B+. You will have to find a hat to put your Piezo microphone, or go with USB…

It's difficult to make a Audio input as it requires a efficient and fast ADC to convert the signal and this is not something present on the Raspberry 3B+.

Note that USB may have latency compared to GPIO HAT based solutions. But going USB allow you to reuse the device on a standard computer.

Raspberry Pi 3 audio input?
