I'm working to prepare research article for my project. While preparing for it, I've gone through the topics like Gaussian mixture model and Fourier transform for voice classification problems. I've got sounds from the sources(probably the recorded voice of the different peoples).
Can I perform DFT on those audio files and pass the points from the DFT to the the Gaussian mixture to extract the features from the audio files?
Later the weights from the Gaussian mixture model will be used to compare the sounds.
