1. Record 15 seconds of your speech I a noisy environment (use sampling frequency of 12 khz)
• Take a 32.5 msec frame in the middle of the recorded speech (make sure there is a speech in the selected frame)
• Obtain the power spectrum by using
 Periodogram
 Blackman-tukey approach (L=32,64,128) and
 Welch barttlet approach (K=1,4,8)
• Plot these and discuss what you observe
