Tool/software:
hello
i am trying to separate the mixed voice coming from the handset terminal of a phone using DSP.
i noticed that the other person's voice (speaker signal) and my voice (microphone signal) are mixed and output from the RJ11 port of the phone(speak into the phone's microphone and you'll hear your voice on the speaker). My goal is to completely separate my voice from the other person's voice
i think it can be solved by utilizing DSP and FPGA.
i am thinking of utilizing the microphone signal to try and separate the mixed signal on the speaker side.
however, although I have envisioned this, I am not sure if it is technically possible.
utilizing the Fast Fourier Transform (FFT) and Phase Inversion, it seems possible. but I've never worked with DSPs before, so I'm not sure.
