Extraction of LPC, LPCC, and MFCC Coefficients for a Vowel and an Unvoiced Consonant with Spectral Analysis

1. Implement LPC, LPCC, and MFCC coefficient extraction for one vowel and one unvoiced consonant using MATLAB, focusing on autocorrelation method for LPC/LPCC. 2. Perform LPC-based power spectrum estimation for both speech signals using 5th, 10th, 15th, and 20th-order coefficients, comparing with FFT power spectrum in a single plot. 3. Generate variable cross-section vocal tract simulations using log area ratio method with 10th-order coefficients.
