Speech and hearing disorders can have a huge impact on somebody's social life and can also affect them in their career, causing them many financial difficulties. This is where Clinical Phonetics comes into use. In order to help people with their speech and hearing, we need to be able to understand how things work normally. Thus, knowing how speech sounds are produced (Articulatory Phonetics) and how they are perceived (Auditory Phonetics). By knowing what is right, we can recognise what is going wrong and can finally help the person with their speech or hearing disorder!
