Help Please

Hi, I am searching for a design to a speech acquisition circuit schematic .
our purpose is only to collect any human speech and draw it on the computer screen.also it is required to implement this project on a PCB to be a computer card.

Is it supposed to recognize speech and translate to text?

Or just capture human speech sounds? If so, does it have to distinguish between any sound and human speech?

Most speech to text is done in software with the audio signal captured from the system's sound card.

U can use Praat. It is a free scientific software program for the analysis of speech in phonetics.
