MFCC implementation in simulink

Hellow all, i was doing a project on audio recognition. I did train my classifier in matlab by extracting features using the mfcc matlab function. but i couldnot include this function in a matlab function block since it says it is not supported for generation. so I was having doubts of if the cepstral feature extractor block has the same functionality as the mfcc function in matlab. i would kindly be waiting for ur answers. Any guidance ,please.

hai sir!

how will you extract the mfcc in matlab?

Hi Mihret,

The MFCC function (in Audio Toolbox) supports codegen as of R2019a.

The cepstral feature extractor block has the same functionality as the mfcc function in matlab, so you can use that to compute MFCC in simulink. Note that the block is designed for streaming, real-time scenarios, so instead of feeding the audio signal in one long vector, make sure you break down your input into (optionally overlapping) windowed frames before feeding them to the cepstral feature extractor block.

HTH,
