1. EE Compute the smoothed spectrum using cepstral processing.
non-EE Compute the spectrum using Linear Prediction analysis.
2. Extract formants, and plot the formant contours.
3. Perform VAD using zero crossing rate and short-term energy.
4. Extract pitch using autocorrelation method or cepstrum method after performing VAD.
Record a male and female voice for the sentence “We were away a yearago.” Compute the spectrogram, perform VAD, extract formants and pitch. Overlay the formant and pitch curves on the spectrogram
