Homework #4 1. Load the word "Washington" at 8kHz sampling rate. a) Estimate the auto-correlation values rx[0], ..., Ix[10] from "a" portion of the first recording b) Design a 10th order LMMSE predictor for "a" part of the signal. c) Estimate the pitch value using the autocorrelation method. d) Generate speech using a pulse train and the vocal tract model obtained in part (b). Submit the generated sound in .wav format as an attachment. 2. Repeat Q1 for "o" segment of your recording. Have you noticed the difference between the sounds that you generated? Homework #4 1.
