Lecture Summary (12/07/2006)

The topic of this session was "Phonetics: realising sounds".

First of all Mr Gibbon presented once more his famous model of signs and their position and relations in the conceptual and the real world. He told us that phonology is part of the conceptual world whereas phonetics deals with the utterances themselves and by consequence is part of the real world.

After that we looked at the different aspects of speech: production, transmission and perception. This led to the different domains of phonetics: articulatory phonetics (production), acoustic phonetics (transmission) and auditory phonetics (reception). The three domains of phonetics are also called phonetic cycle.

Mr Gibbon started of course with the articulatory branch. He showed us some pictures displaying the midsaggal section of the head. The articulatory organs are the lungs and the vocal chords in the larynx. Another very important aspect are the articulatory positions: uvula (with back of tongue), pharynx (with velum (nasals)), velum (soft palate) (contact with tongue: velars), palate (hard palate) (with tongue), alveolar ridge, upper teeth (with tongue; with lower lip) and upper lip (with lower lip). In this context we took a closer look at the midsaggital section and the saggital section.

Then we dealt with the description of sounds which contains of two levels. On the one hand there is the general pronunciation representation in the lexicon. The phonemic transcription gives just enough detail to distinguish words. On the other hand if you need detailed representation of speech pronunciation you have to use phonetic transcription based on articulatory phonetics.
