Acoustic Phonetics

Reading: C&Y pp. 206-232, 236-253, 275-292.

Tasks:

Find definitions (and graphical illustrations) of the following concepts on the web and in your textbook:

1. Time domain:
   1. period
   2. waveform
   3. oscillogramme
   4. amplitude
   5. energy
   6. intensity
2. Frequency domain:
   1. frequency
   2. pitch
   3. fundamental frequency
   4. harmonic, overtone
   5. formant
   6. spectrum
   7. spectrogramme
   8. fourier analysis
   9. fourier series
3. The relation between frequency and period
4. Signal processing:
   1. sampling rate (Hz)
   2. sampling theorem (Nyquist theorem)
   3. resolution (bits)

Hints:

1. Look for examples of English speech, analysed according to these concepts.
2. Look for formant diagrammes.
3. Check for definitions of noise (German: Geräusch) vers. resonant sound (German: Klang).

In the last section of the class brief reports on these topics will be provided by selected desks.

At the end of the class I will give an overview of the essential aspects of Fourier series.
