 Welcome, this unit introduces the phonetic machinery for the classification of consonants, which is necessary for the understanding of more advanced concepts of phonetics and phonology. And furthermore, we will practice a lot. In the virtual session we will define the parameters according to which consonants can be classified phonetically. We will look at the phonetic notation used for consonants and we will exemplify all consonants by means of animations and audio examples. The question sheet may help you with its hyperlinks and video links. The mastery worksheet is a simple test about the classification of consonants. After the virtual session, you should not find it difficult at all. And the practical is truly practical. It involves several ear training exercises and tasks with consonantal symbols. So, all in all quite challenging. But if you invest a reasonable amount of time, you'll be fine.
