 Welcome. The starting point for any auditory analysis of speech is the study of the human hearing system, that is the anatomy and physiology of the ear and the brain. We will look at these in this unit. In the virtual session where you can use the question sheet as default guidance, we will look at the anatomy and the physiology of the human hearing mechanism from the outer ear to the inner ear and we'll also consider the links into the brain. We need these details to understand how the speech signal is processed. The mastery worksheet is an input task where you have to identify and name specific positions in the human auditory system. Refer to the virtual session if you can't remember while doing this worksheet. And the practical is just a repetition of it all, not more and not less. So all in all a relatively basic unit, but important to understand human perception as a whole.
