👉 Mel-Frequency Cepstral Coefficients (Mel Fluids) are a set of features used in speech processing and recognition, designed to model the human auditory system's response to sound. They transform raw audio signals into a more compact and meaningful representation by first converting the frequency spectrum into the mel scale, which mimics how humans perceive pitch. The Mel-Frequency Cepstral Coefficients are then derived through cepstral analysis, capturing the spectral envelope of speech signals. These coefficients are particularly useful for tasks like speech recognition and speaker identification because they effectively represent the temporal and spectral characteristics of speech, making them robust to variations in pitch and speaking rate.
