  1. filters - Signal Processing Stack Exchange

    Jan 29, 2020 · In the book here, they apply liftering, as a final step of MFCCs features extraction, to isolate the system component by multiplying the whole cepstrum by a rectangular window centred on …

  2. Using MFCC in spoken words recognition - Signal Processing Stack …

    May 10, 2013 · We're trying to implement a "simple" speech recognition application in MATLAB (isolated words from a very limited dictionary). We've been trying the following methods: Extract MFCC …

  3. MFCC - Significance of number of features - Signal Processing Stack ...

    Feb 17, 2016 · 4 I have been doing some readings on the computation of Mel-Frequency Cepstral Coefficients (MFCC) and further use of Vector Quantizers (VQ) for recognition purposes. I am …

  4. MFCC calculation - Signal Processing Stack Exchange

    Where is the my mistake in calculation? Cheers! Celdor EDIT: I understand now why the first MFCC coeficient is very low. If I look at DCT II, its first component is just a straight line: This is equivalent of …

  5. What is the purpose of the log when computing the MFCC?

    The steps of computing the Mel-Frequency Cepstrum Coefficients (MFCC) are: Frame blocking -> Windowing-> abs(DFT) -> Mel filter bank-> Sum coefficients for each filter-> Logarithm -> DCT But …

  6. Understanding MFCCs - Signal Processing Stack Exchange

    Jun 7, 2020 · I am doing research about emotion recognition from speech, by applying machine learning. Most papers are recommending using MFCC features. Therefore, I am currently trying to …

  7. Applying DTW on MFCC frames - Signal Processing Stack Exchange

    Mar 23, 2016 · I want to use MFCC (Mel-frequency cepstral coefficients) and DTW (dynamic time warping) algorithms to make a speech comparison script. I calculated MFCC and got 13 coefficients …

  8. Understanding MFCC - Signal Processing Stack Exchange

    Jul 23, 2020 · MFCC is represented by 39 values for each window frame. 12 values are the mel filter-bank and we get 13th value by taking DCT [ Is this right ]? So rest are the delta and double delta and …

  9. what is the output of MFCCs? - Signal Processing Stack Exchange

    Apr 13, 2019 · TL;DR the x-axis is time and the y-axis is coefficients which means they have no units. Let's go through the process of manufacturing the MFCC features while emphasizing measure units …

  10. How to calculate MFCCs over a narrow frequency range?

    However, my MFCC matrix outputs as a bunch of NaNs, presumably because the range is so narrow. This either means that MFCCs are an inappropriate measure in general for such a narrow frequency …
