what values should i calculate from FFT of two audio file and compare them

[warrior]

I want to compare two audio files(voice recording) and find whether they are identical or not (to some extent).I have come up with FFT(OouraFFT).I have integrated code and gave my audio file as input and "calculateWelchPeriodogramWithNewSignalSegment " is called.There is a term spectrum data used in "calculateWelchPeriodogramWithNewSignalSegment " method.now what should i use to compare two audio files.please anyone explain the concept for using FFT to compare two audio signal(speach signal).Further what should i proceed with?Any valuable information will be more helpful.Thanks in Advance.

You're asking a lot of different questions all related to a very specific coding issue which is no longer reasonably in the expertise domain of most members here. I will kindly ask you to stop bombing this forum with your FFT questions and ask that you seek out your answers elsewhere, perhaps Google or wherever it is you located the FFT library you're using.
