Adding PLP with MFCC for feature extraction on Whisper

I have followed this amazing blog Fine-Tune Whisper For Multilingual ASR with :hugs: Transformers on fine tuning whisper on my dataset . I wanted to use PLP as feature extractor and run some experiments .

I see feature extractor is using MFCC by default .
Can you please give some insights , how do i do this ?
