1) Explain the human speech production mechanism. 2) Write the time domain and frequency domain properties of the voiced and unvolced speech. 3] Find the minimum reasonable sampling frequency of the human speech signals using the sampling theorem. 4 Explain the importance of the filtering process for speech and audio signals. S] Write a matlab script to divide the whole speech (H.22.16k.wav) into the frames. Length of the frame will be 16. You will construct the frame matrix A. (consecutive columns of the matrix A will be the consecutive frames of the speech that you obtained.) 6) Write a matlab script for low-pass filtering of the speech given as sp02_restaurant_sn5.wav. The cut-off frequency of the low-pass filter will be 3 kHz.
