(a) Design a system for the creation of frequency-time landscapes of speech (see Illustration 72.

(b) Divide the signal up into increasingly small, overlapping windowed blocks and observe the changes in the frequency-time landscape.

(c) Represent the frequency-time landscape as a bed of nails pattern by selecting the bar representation of the signal (see Illustration 70).

(d) Represent the frequency-time landscape as a sonogram (see Illustration 73). Set the colour scale in such a way that the areas of different amplitudes are represented in an optimal way.

(e) Do some research (e.g. on the Internet) to find out what sonograms are used for in science and technology.

(f) How can vowels and consonants be distinguished in sonograms?
