As machine learning and deep learning continue to revolutionize image classification, it is high time to explore the development of adaptable models for audio classification. Despite the challenges associated with a small dataset, we successfully crafted our models using convolut...
But when i use this code, it gives me different result, for example if i try to extract the folder of 97 audio wav files, the result i get contains perhaps 171 rows and 14 columns. Please anyone can help with this issue by helping me to modify the code for it to work pro...

Feature extraction is extraction of small information from the available audio wave signal. That information can be used to represent the particular speaker. For SI, There are many feature extraction techniques like LPC (Linear Predictive Coefficients), MFCC (Mel Frequency Cepstral Coefficients), PLP ...
