 Welcome to one of the most fundamental offers on the Virtual Linguistics Campus. The repository VLC 102 Speech Science, a collection of e-learning units all about speech, production, physics and perception. To make the content as accessible as possible, VLC 102 is full of interactive multimedia. Here are some examples. We use interactive diagrams and images. We have integrated sound samples wherever suitable. The intonation of a language can be described as its melody. We have many interactive charts that not only describe but also show the articulation. At a, a, a. We use sound and visual illustrations in many ways. And the highlight are our interactive sound charts with articulatory animations. A, a, a. Or with spectrographic information. E, e. Join us on the Virtual Linguistics Campus and make use of the VLC 102 options that provide you with the background knowledge that is necessary for further studies in linguistics. The whole course is basic. There are no further prerequisites for VLC 102 Enrollment. But let's now see how you can use VLC 102. If you have an account on the OER VLC website, which is of course free. Accessing the repository is simple. Just log in with your personal data. And you will find the repository on your personalized dashboard or in your course overview. A click on the bottom of the VLC 102 tiles leads you to the repository start site. Where you have access to all modules starting with the content description and the preliminary section with advice and help on how to use the units. And here is how we organize the content of VLC 102 for you. After an overview of speech in the speech chain. Part one looks at the anatomy and physiology of speech, especially at Airstream mechanisms and phonation. Part two deals with the basic units of speech that is with consonants and vowels. And with those elements that operate beyond these segments. Part three is dedicated to acoustic phonetics and introduces you to sound waves and the techniques of analyzing them. The final part looks at speech perception. The human hearing mechanism first and then the ideas about how we actually perceive speech. VLC 102 is thus arranged alongside the three P's production, physics, perception. Or if you wish, along the three A's articulatory, acoustic and auditory phonetics. By the way, the final unit serves as a transition from phonetics to phonology where the letter constitutes an additional VLC repository. This list of units is being updated and quality assured on a regular basis. And our teaching and learning concept, well, studying online on the VLC simply means go through each unit at your own pace whenever you want to. Take off an activity you have worked through and make use of as many VLC options as possible. And if you don't know what to do first, usually how to proceed options at the beginning of each content section. And as most of you know, each unit should be finished with a mastery test where you can earn your personal topic related VLC batch. And at the end, if your score is 70% or higher, you will be awarded the Statement of Accomplishment certificate. Maybe you prefer using your mobile device? Well, if so, feel free to download the Moodle app, login and study where and whenever you want. Well, that's it. The rest is up to you. Thanks for your attention and see you on the Virtual Linguistics Campus.
