Disclaimer 1 : This text is simply an introduction to MFCC options and is supposed for these in want for a straightforward and fast understanding of the identical. Detailed math and intricacies usually are not mentioned.
By no means having labored within the space of speech processing myself, harking upon the phrase “MFCC” (very often utilized by friends) left me with the insufficient understanding that it’s the identify given to a specific form of “function” extracted from audio alerts (just like edges that represent a form of function extracted from photos).
It took me fairly a little bit of studying from a number of sources to understand the novice’s understanding of what MFCC options are. So I made a decision to assist out fellow people in want by compiling the data I collected in an easy-to-understand method.
Let’s start by increasing the acronym MFCC — Mel Frequency Cepstral Co-efficients.
Ever heard the phrase cepstral earlier than? In all probability not. It’s spectral with the spec reversed! Why although? For a really primary understanding, cepstrum is the data of charge of change in spectral bands. Within the standard evaluation of time alerts, any periodic element (for eg, echoes) exhibits up as sharp peaks within the corresponding frequency spectrum (ie, Fourier spectrum. That is obtained by making use of a Fourier remodel on the time sign). This may be seen within the following picture.
