Took two same speech audio signals(apple-like sound) and remove noise by using the Thresholding method.
Normalized both signals and create frame for both signals.
Applied various filters to remove remain noise and calculate Mel-frequency cepstral coefficients(MFCCs) of both signals.
Got 38% similarity by Cosine Similarity method.
