 Hello! Three central mechanisms are responsible for the production of speech, the lungs, the larynx and the vocal tract. They will be discussed in this unit. In the virtual session with its question sheet as default guidance, you will be informed about respiration, phonation and articulation. Make sure that you get to know the articulators. You will need this knowledge to pass the worksheet and to cope with the data in the practical. The mastery worksheet is an input task where you have to identify and name specific positions in the vocal tract. After the virtual session, you should not find this task difficult at all. Similarly, the practical. Again, it's mainly about articulation but also involves a question about the specific properties of human speech in general. All in all, a fairly technical unit, but it is important to understand these basics for further studies in phonetics.
