I am looking for a way to count how many unique voices are in a short audio file. I am not interested in what they are saying but just identify unique individuals (e.g. there are 2 unique voices in this audio). Could anybody point me to good resources?
I do not know the answer. It worth noting that sound is usually studied in the frequency domain (or time-frequency) - each voice has specific timbre. So the input to the neural network model can be Fourier Transform (FFT, STFT) of the signal.
