Question: Computer Assignment: (a) In the speech files available for this book (see Preface), you will find a file that contains 16-bit integer samples of the vowel /0/, sampled at an 8-kHz sampling rate. Extract 512 samples of this speech sound and plot the time waveform. Next, apply an FFf to the segment and plot the magnitude spectrum.
(i) What features characterize the time waveform?
(ii) From the magnitude spectrum, estimate the fundamental frequency. Is this a male or female speaker?
(iii) From the same magnitude spectrum, estimate the formant locations. How do your measurements compare to typical values for the vowel?
(b) In the same set of computer files, you will find some vowel files whose phonemes are not labeled. For one or more of these files, repeat the steps of part (a), and determine which vowel the file(s) likely represent(s).
