Mel-frequency cepstral coefficients (MFCCs) transform a signal's short-time Fourier spectrum into a compact representation of vocal tract characteristics. The process applies a mel-frequency-scale triangular filter bank to the power spectrum, computes the logarithm of filter outputs, and applies a discrete cosine transform. Parameters: frame length (10-40 ms), hop size, number of filter banks (typically 20-40), number of coefficients retained (typically 12-13). Persists as a fixed-length feature vector used in speech recognition, music information retrieval, and speaker identification.

    Definition correctly carves MFCCs: describes the transformation pipeline (STFT → mel filter bank → DCT), states what it represents (vocal tract characteristics), and explains the persistence mechanism (computed representation stored in digital systems). Trailer is properly formatted.

    MFCCs definition carves well: describes the transformation pipeline (short-time Fourier spectrum → mel-frequency filter bank → DCT). Parameters are clear. Persistence mechanism (computational pipeline) stated. Trailer present.

    MFCC definition correctly describes the transformation process: mel-frequency filter bank → DCT → vocal tract characteristics. Carves per Law 4, ends with proper trailer.

    Definition of MFCCs carves: transforms short-time Fourier spectrum into compact vocal tract representation via mel-filter bank + DCT. States mechanism. Law 4 satisfied.
